12V Cummins Must-Have Upgrades
this is Corey Willis with PPI and you're listening to the diesel pot gasps I'm Adam battenburg from diesel world hi this is Dan owner of Danziger performance I'm Kristin Roth of beating diesel I'm Brayden police and you're listening to the diesel podcast what is going on diesel nation we're excited to

have

you guys with us today on the diesel podcast today's episode is gonna be about the 12-valve

Cummins

engine and specifically in the second gen trucks we've had a lot of questions from people who

have

either just picked them up or thinking about getting a 2nd gen 12 valve as far as what are some

must

-

have

upgrades

that they should do or maintenance items there things are gonna

have

to address depending on the mileage or how they're gonna use the truck maybe it's gonna be a daily driver they're gonna use it to tow a trailer or you know go farther and make it into a street truck or race truck and joining us today is Garrett he is the founder and owner of pure diesel power and he's gonna be answering these questions and he's out of 12 out pulling truck and pure diesel power has played a vital role in the diesel industry for a really long time and so we're gonna be chatting with him today asking him these questions and also more about pure diesel power as far as what they do and you know trucks that they work on and the kind of questions that they get from a lot of diesel owners whether they've you know under truck for a...
12v cummins must have upgrades
really long time or it's just one that they picked up alright let's get to the podcast with Garrett and chatting about the second gen 12-valve

Cummins

platform Garrett welcome to the diesel podcast I'm excited to chat with you today it's been a long time coming and we were able to to connect and there's a ton of second gen 12f questions that I

have

for you so we're excited to

have

you on the show today yeah thank you how pretty having me out we've had a lot of new listeners over well this year and even in the you know last year and a lot of times our first time diesel owners and well most diesel enthusiasts

have

heard of pure diesel power and

have

probably met you different shows and events you know throughout the years I wanted to start by having you explain a bit about your company what you guys do where you're located and you look what's your kind of bread-and-butter is there appear to be some power sure so basically I started it in 2006 basically with a self foreign apartment and I was was a you know fairly active in the diesel thing he knows a bit an enthusiast since my early early years and basically grew from there we had a couple different locations finally moved into a you know was it old building supply store kind of like my nards or home depot and we've got a 28,000 square foot facility now the showroom is large we got a lot of room for you know walk-in customers I've got about 8,000 square foot shop pretty good crew here...
12v cummins must have upgrades
we've grown a lot over the years the bread and butter I guess would be is we do a lot of a lot of parts sales ship all over the world we stock a lot of random different things that you know together then we also do some dropship stuff we the majority of the business is just you know selling parts and shipping all over the world but we do do these amount of shop work mainly repairs and some performance and one of the things that and I think a pure diesel power and the website and the things people would always tell me is if they're looking for a commons part chances are you guys probably

have

it whether it's you know a

Cummins

gasket or just tons of different things like fur that repair that maintenance side if you want an OEM part where you want aftermarket you guys

have

a ton of that and that's why when I was thinking you know what what kind of second gen questions what kind of guest can I

have

onto a sedan that's why you popped in my head you know right away is in you know keeping those those trucks running which like I said with a lot of new diesel owners they're these trucks or you know getting in the hands of a whole new a whole new generation of diesel owners and I wanted to ask you you know as far as the second gen stuff and specifically 12-valve is that it was that which you started on you as far as being an enthusiast it was that yes something that you know is your first truck or did you get into it a little bit later with the common rail...
12v cummins must have upgrades
stuffer as far as owning a diesel and in the performance side where'd you start out well I actually was a little bit misstated when I was younger I had a Ford 73 and I wizened up and picked up a 98 12 out of Texas and yeah pretty much I pulled it shortly after that and pretty much was all downhill from there you know what started out at you know 250 horse it was slightly modified when I got it and you know when I got out of the sport as far as truck pulling it was right around 1,300 horse thanks yeah they're they're fun trucks I

have

never had one I've talked about in my podcast before that that's probably that's something I want one day and I don't I don't know if it's a simplicity or the reliability or just that body style which I was a kid when you know they came out and that it was so different than the forger the GM's at that time and they've always had that kind of a soft spot in my heart and you know I wanted to I wanted to ask you but you basically just kind of go through some questions that would be on different listeners and when they're looking at a 12o maybe they find one they just bring it home what are some things that you've seen that are gonna be maintenance issues or probable repairs or things I should just look at like we know the transmissions whether it's a manual with the clutch or the 47 rh or 47 re that that's probably going to be an issue but once we look at the engine what are some things...
that a new owner should be aware of and and take a look at well the biggest Achilles heel to the

Cummins

12 valve would probably be the killer Dalton or at ADP I guess if you ever go to purchase a truck from somebody used if the owner well either way I would definitely ask the owner if the KDP has been tabbed if he gives you a dumb look and I would probably highly suggest reading up and and seeing what's all involved basically there's a dowel pin and the and the cover that can buy it with vibrate loose over time and generally it's higher miles but it's more of a more of a when it's going to happen not if it's going to happen type thing you drive it long enough it's probably going to fall out and wreak havoc it falls into the gears either cracks the timing case or I are seen in severe cases you know braking cam gears crank gear stuff like that and so it's best to definitely address that because it's you know a lot of money to fix if either one happens so that would be something I would definitely look into and get it get it apart and tab it's not that big of a job and both these trucks that high miles

have

a linking front crank steel anyway so you can kind of do two birds with one stone you can replace that crank seal and tap the killer dolphin is it something that somebody could do at home or would it be better to take to a shop or it just kind of depends on how comfortable you know somebody may be and working on their own truck I'd...
say if you've got decent mechanical abilities and you know do a little bit of reading it's not that big of a job it's it's just tedious you've got to take the fan off and the fan shroud some people do take that off as well but it's not that bad of a job to do at home if you're questioning it I mean I thought of a 1 to 10 scale I probably say it's probably a 4 as far as difficulty it's not bad at all that way if I think of the rest of the engine yeah obviously you know the turbo could be an issue if it's the factory one and if the truck has higher mileage but outside of that would it be mostly just maintenance or wearable items like boots and clamps and you know kind of things like that that you may need to replace yeah you know cooler boots seem to be real common on these one thing and I don't know if things just shift over time but if you if you take a look on the indoor fenders on the lower intercooler boots they tend to rub and they'll rub holes in the intercooler boot or you know rather where gets a weak spot then it blows out in that spot so I can leave you on the side of the road especially if you're towing a trailer or something like that another item I would probably look at if you get any mileage 12-hours the you know performance wise is overflow valve basically maintains pressure in the injection pump to keep at an auto rate you know the stock one has a spring and it those Springs get weak and they also break so...
that would be a cheap maintenance thing to do to keep the performance where it's supposed to be on the fuel side what do you see there as far as you fuel from the tank to the pee bump and then even into the even into the injectors I do see some issues of the factory lift pump they're not but they are way more reliable than you know the newer you know pumps they put on like the VP trucks you know they

have

a lot of fuel sending unit the issues you know as far as far as reading the right level of fuel but overall the fuel systems really stood out there are some trucks say it's usually about a 97 through 99 yeah obviously the twelve valves only 97-98 the fuel housing canister is it's more of a cartridge style filter and those fuel housings tend to crack we do offer a billet version of that that allows of you to spin on filter and we can also integrate the fuel heater and you know still use the 94 to 96 style fuel filter that's been a very popular upgrade with people on those trucks with the injectors what do you guys in there I don't see injector wise they're they're pretty stout it's a you know a fully mechanical injector very few failures obviously is miles I mean there's definitely you know some performance game to be had you know by replacing you record you know 12,000 miles but as we've seen trucks in here with the wall over that on stock injectors so it's not a weak point reel too bad there you know you do see you know the...
return line sometimes you

have

leak leaks around the mandrel bolts and stuff like that but not too bad there you know we do sell a lot of like contagious diesel and dynamite diesel injectors for these trucks you know even even you're just replacing a stock set of injectors you could do like a 5 by 10 or 5 by 11 injector and gain some power and fuel economy and you know still

have

a real streetable beef and truck and then the I know what some of the exhaust brake kits and just in general especially when modify we get into some valve train work I wanted to ask you about that as far as valve springs and what what you guys recommend for upgrading them and when you need to upgrade them Noelle spring wise the all the stock cylinder heads

have

a little heavier spring on the exhaust side than the intake the very popular operators they call it a 60-pound valve spring which is that it's not actually a 60-pound seat pressures 60 pounds heavier than stock we sell a lot of those from there a decent spring but you know if you want to go high-performance I would definitely recommend a set of safe Hamilton's or contagious diesel and Springs that

have

better retainers and keepers a lot of people like to put in a 4000 rpm governor spring kit where they run really well but the problem is you run if you run over 30 for 3500 rpm can a lot you're gonna

have

keep you're gonna

have

a valve postural keeper and drop a valve and that's gonna make fun expensive repair we got any...
question as far as well or as far as what kind of spring kit to go with and you had mentioned you know the operating RPMs is there as far as what which set to go with is there is there a rule or recommendation or certain set of questions you guys will ask a customer when they call in or if they stop by the shop as to as to which set to go with well the most common Springs are 3000 4000 and 5000 rpm if you're wanting a truck to throw in a set of governor springs and basically billet florid all day long and probably not cause any damage as far as valve trainer I would definitely stick with a 3,000 if you are wanting to crank higher than that you know I would definitely say the 4000 or 5000 is a good option but 5000 definitely more you know drag strip and sled pulling and oh there are a lot of people who street them but you know they do they are pretty responsive it can be kind of touchy throttle wise the for thousands I've seen a lot of guys run those on the street but you definitely

have

to keep in mind the valve train issues if you do decide to use that rpm so it depends on what kind of person some people you know they put a 4000 rpm kitten with the intention of doing valve springs and retainers and keepers later so kind of depends on their upgrade path if they plan on just leaving it mainly stock and you know what save our p.m. then I'd then I would say stick with a three thousand I think that as far as modifying the trucks and getting a bit more power form see...
not necessarily like a race truck but you know you tow a trailer you want to

have

a bit more power what is a sweet spot as far as

upgrades

that you would recommend for somebody that daily drives this truck they want it to last they don't necessarily want to you know pull the pull the engine and rebuild it or don't you

have

any plans to do you know a full billet shaft 47 or a year or something like that what would be a list of

upgrades

you tell them to look into so you're talking like baby the 400 450 horsepower range yeah see like four 450 maybe even 500 but just kind of making that ultimate towing 12-valve set up I see that what's the ultimate towing I would probably say you know if you're wanting to say the stock turbo and tow I would probably wouldn't go anything bigger than like a 90 horse injector or a lot of people call them like a 5 by 12 but there's a lot more potential there horsepower wise if you'd put a bigger turbo on real popular towing turbo is like a 6368 turbo there are some hybrid like 64 64 or 64 67 stock turbos you know they're based on like the whole set HX 35 frame anything above about 500 horse you're gonna

have

issues with head gaskets more than likely and then anything over about 40 and 50 horse on the sock mp40 500 like a five-speed transmission you're gonna

have

issues with the input shaft if you beyond them and then you know beyond that you know it's about 600 horse and the 4500 just gonna wreck fifth...
gear pretty consistently transmission wise you know billet input shaft I would definitely recommend it anything over save you know 450 to 500 horse because they they tend to break those especially if you get a triple disc inverter in there where you're getting a lot more power to the ground yeah the I think you too with the added power it's also fun and especially if you're towing you know you're gonna be it's gonna be pulling more weight and you're gonna

have

that power on tap and it's just it's better to spend the money on that input shaft and the build or in the package that you know somebody orders then not doing that and then being stranded on the side of the road and having to be towed and then pull the transmission and

have

n't rebuilt or send it back and that can be it can be costly and frustrating to deal with yeah absolutely it can make for a bad day you're you're definitely better off to upgrade it before you break it you know especially if it's a daily driver and although you know a lot of people are buying these trucks and they want to daily drive them well you go beyond them and you're not set up for that kind of power you're gonna break parts and might be without your daily driver for a couple weeks and not a lot of people can do that very easily with 12 of enquiries that you guys you get there either on the phone or in the shop what are most people looking to do with them are they doing this daily driver...
towing setup or is it more of a project kind of drag truck or race truck and and that's what they want that's the platform I'd say a good majority would be just people that want a more fun you know more playful Street truck now there are still people looking for big horsepower but it's easily dwindling down over the years you know people are moving towards towards newer platforms but they're absolutely nothing wrong with the 12-hour platform is just the variable timing and whatnot is a lot nicer for making power so you know people kind of go on to that that platform but I'd say majority is you know somebody's got a truck and you know a farm truck and whatnot and they want to part the tow a lot better and you know you can get them up to like set on the starter both Ford horses doable I would definitely recommend an exhaust temperature engage so you can watch that this week make sure you make it safe power and then you know as you go intercooler it's potentially even if they're not rubbin holes with the fender you know you probably want to get those replaced just because the stock ones are not that good as far as higher power and higher boost as far as the suspension is that kind of like most other dodge generations we're going into it we know at some point we're gonna

have

to upgrade steering components and in different parts of the suspension yeah steering is a mysterious elf is fairly subpar the main issue is going to be the the...
track bar the track bar it's got a ball joint type end on the end of it and on the frame side we sell a selling stock a lot of track bar retrofit kits which basically allows you to retrofit over to a third gen style track bar and that way you've just got bushings on both ends and the steering itself I mean you know you get decent decent quality and you know parts from same at the higher end steering parts they they do pretty well but the track bar is the biggest thing to look at it can cause death wobble especially there's a also an issue with the the arm that runs from the Tippmann arm to the axle side of the steering the pitman arm shaft or the staff that holds pitman arm actually side loads when you xx steers so they offer a they called a steering box brace or a DSS there's several different connotations for it but basically puts a brace on the pitman arm so to the side load that also will keep your just it'll keep your steering feel a lot better it helps eliminate a lot of wander and then also you know you don't take out tipping arm or the seal come out of the steering box you don't take out the seals so that helps a lot the steering box themselves you know a lot of these trucks are higher miles so we replace a lot of them will say a red head box or Bergesen box that'll really help with overall handling and you know tighten up steering one of the things we were chatting about before the podcast when we were talking about your company and...
and the things that you guys do there was the the staff and the people that you

have

there whether someone's calling or stopping by the shop dropping off their truck and I wanted to ask you about that as far as putting together the team that you

have

when somebody contacts you guys how do they who helps them are there are there specialists in different you range trucks if somebody walks in as like hey my trucks having a problem how do how do they get you know through or to the service department and and you know with the space that you guys having all the products that you guys stock I'm sure you know is also a logistical you know challenging something you guys stay on top of really well but I wanted to ask you about the people that make up a pure diesel power so we've got a shipping department you know we gotta leave that does all the job ships and handles you know ship you know receiving as well we've got a tech department we've got three strong techs you know one one gentleman is more of a Chevy guy one's more of a Dodge guy and then one's more of a kind of a catch-all he he's got all knowledge of all three under his belt we've got a service department with a service writer and a mechanic at currently and we've got customer service department as well since there's some guys and gals in that department if you do call we do

have

a you know a phone menu where you can talk to either customer service tech or our service department I...
was just thinking so when people hear you on the podcast when I can't want to talk to Garrett they're gonna really get in touch with you it's pretty difficult I spent a lot of my day helping with the shop diagnostic said you know and I'm just day-to-day you know you know decisions and you know advertising stuff like that so it's fairly difficult to get a hold of me a lot of people reach on the purities app our Facebook page as well and so I kind of monitor those and help as needed but it's hard to get me but I mean it's a definite out of a out of the equation I will I do talk to the customers occasionally and I definitely love talking my people it's you know it's what makes this a great occupation and it's a great industry to be in I think one of the things gonna be so tough or challenging for a business and a shop is like as an enthusiast somebody's gonna

have

or somebody who owns a truck is that's what their interest is going to be and there's so many different obviously you generational you know engines and different model changes and then different brands and you never know who's gonna call or you know or stop by the shop it could be that you know ninety four twelve valve that you know wants to build a drag truck or it could be you know lb7 Duramax that the guy just wants to be able to tow a little better or could be a you know a 2015 truck and I think it's it's definitely something you guys are known for the...
service that you guys

have

and that it's extremely commendable to be able to put together you know a team of people that can handle any kind of inquiry or any kind of build or any kind of maintenance that someone's gonna need whether they call you or they stop by the shop we definitely pride ourselves and you know somebody's got a difficult question that it's kind of a head-scratcher we do our best to do you know research and house if possible you know talk to staff we've got a lot of different people under the roof that

have

a lot of different experience with different vehicles sometimes we may say hey you know let's let me

have

your name and number and let me do some research on this we'll give you a shot back we do a lot of diagnose diagnosing over the phone it's you know it's something I pried out us and able to be be able to do the other thing is you know we try to

have

top-notch customer service with you know if you order something we try to get you information within it within a day whether you know there's a delays with the item or hey we're honest item but we do

have

this item that we could potentially send instead you know based on your approval so I yeah it's definitely a you know it's definitely it's this undertaking but like I said I'd do it for my customers and said really enjoy it

have

things really been challenging the last three or four months from the logistical standpoint with you know like...
shipments and getting products and all that kind of stuff with you know the pandemic and just everything that's been going on yeah we've seen some a lot of shortages we've seen a lot of shipping delays you know certain product lines you know they're six weeks out plus or just an MTA you see yeah just a lot of people a lot of people are you know more on edge more you know because you can tell people are frustrated they've been locked in their homes or you know and out of work so we you know people see me more on edge so you you're dealing with a little more agitated customer sometimes if something does go wrong but as far as the back to the you know the Cova tough as far as staffing wives we've got a lot of people working from home you know they've got you know health concerns with the with the situation so things a little more difficult you know it's not it's a lot harder to work with everybody not on the same roof you can't just go talk to somebody

have

to call them and the city's away from their desk well then it's you know it's may be playing its game of phone tag but oh and all you know you know sales

have

been really well I don't know if people are just fixing their trucks are working on them constantly if they're stuck at home but you know no complaints there we're just doing our best to take care of the volume with the staff staffing changes currently there was just a ton of changes just like you...
mentioned in the way that people do business or the way we can do business just we went from you know being able to call we get our tracking that afternoon maybe that believes the next morning and everything we're all used to that and then it just changed all of a sudden we're you know I've ordered things not about truck parts or anything but they're just like stuck in this UPS like in transit loop for a week or two and it's there's like nothing you can do but it's just been a massive change in and I think the way that you guys

have

have

handled it and still take care of customers during like something incredibly unprecedented like this it is awesome and you know when it's done people are gonna remember that I remember how they were retreated now you guys helped them well yeah I definitely appreciate that we're we're doing our best with the tools we

have

so it's it's definitely been a challenge but I appreciate the you know the input there we're doing trying to keep everybody everybody happy to everybody go in and so that people can build their trucks or Fixer trucks absolutely it was fantastic catching up with you knocking out some questions some of our listeners had about twelve

Cummins

trucks and and like said they've always had a sweet spot in my heart and hearing the answers that that she gave you know it's like I know what to expect if I get one and it doesn't seem you know undaunted to be able to make it...
do you know what I want so we appreciate your time like I said we we know that you're busy and just chatting with us and catching up tell us about pure diesel power and what you guys do yeah absolutely thanks again for having me I really appreciate it and everything goes well and the world goes back to normal here sometime don't forget diesel fans if there's any questions you

have

about your 12 valve truck or really any other truck or you're in Wisconsin and you're close to pure diesel power needs some maintenance done want to drop your truck off just go to pure diesel power calm you can check out all the products that they offer if you

have

questions you can give a call and chat in with one of the crew and they'll be more than happy to help you till next time keep the shiny side up
