3 Things That Will Make Your Engine Last 400,000 Miles

Now that you have oil leaks in

your

car, they can come from many places, it can be difficult to know where they are coming from because as my dad always said, don't assume it's just one leak, you could have a lot of leaks the old fashioned way. was cleaning the whole

engine

, transmission, drying a real pain in the butt and then seeing where the leaves come from, well today

things

are much simpler, you can filter UV rays, it's made for motor oil, a UV light , see bright UV rays and yellow sunglasses, so I can see where the tint is coming from in this case.

I can see

engine

oils coming from here, but when I go under the car I can see that the bottom of the engine has a lot of oil, not in the transmission but just in the engine. We'll turn the engine off, we need it open, it's our best guess, they were worried there was a leak so they put it on real tight, pour it in, put the hood back on. I'm driving about 15 to 20 minutes, okay, now it's driven. It

will

circulate all the oil so we can determine where the leak is coming from, like I said it could be coming from many places, don't just think of one, that's why the die is better, you have to worry about cleaning the old stuff. because the tint

will

shine where it leaks from and you will be able to see any oil leaks so luckily these fit over my lenses so I was able to get the yellow looking weird but let's start looking around you can often see some oil seepage. around the valve cover gasket on an engine has over 200,000

miles

on it, that's not where the oil drips to the bottom, it's just a leak, doesn't show any dye coming out yet, so that's just one thing minor, so we'll lift it up in there and look under the engine, now we have all that and Jacks man and as we walk we can see that it's wet now, you don't really notice much, but when you put the dye on, okay, green spots come out.

Up here, what's up here, well, it's a front engine main seal and when we look at the back of the engine, there's something else. There are also leaks from the rear of the engine. Now the front end is bad enough because you have to remove the front end of the engine and remove the timing belt, you would have to change the front main seal while you're at it, you can also change the oil pump to land the camshaft seal , which is quite expensive, but the rear main seal leak is between the engine and the transmission and you have to remove the transmission from the engine and that costs a lot of money.

I'm going to try this lube shield seal repair. Lube Saver

make

s some pretty good products I've been Trying this because at205 is a little hard to find and this seems to be something similar. I think it could be exactly the same because look it looks like water that's exactly what the at205 reseal looks like so I think this has the same thing in it so what you're doing is some of the engine oil oh Bob no Not only the time in the hotels is work, but I really think it's the same as the resale AT205 because the main hallmarks are the power steering, automatic manual transmissions and differentials, and that's exactly what I use. resealed at205 which I can't get here in Rhode Island no one sells it you have to wait a few hours of running you drive it you have to do it all at once you can drive it over time and it basically even guarantees that it says if it still leaks like crazy after two or three hours of fixing it mechanically.

Well, this doesn't leak like crazy. It hasn't even dripped on the ground here yet, eventually it will, but instead of taking out the engine or transmission, take out the entire front end. separate engine if this is fixed hey, you saved a lot of money. I realize that any car that has over 200,000

miles

on it, the seals will wear out a bit due to the engine turning them properly, let's say this works and it stops leaking. what you have to do is every time you change the engine oil and filter you add another bottle because when you change the oil and filter you also get rid of this additive which to me looks like the same polymer that at205 has, so It has the same address, so I guess it's the same, it even looks the same, right, you have a problem like this that isn't particularly important.

I've seen these

things

really stop them from spilling, but with a small trickle. This way, they had a pretty good idea that this would actually slow him down or stop him completely. Dark Horse, in a perfect world you would take out the engine or transmission, replace the front main seal, oil pump camshaft seals on top of the engine, but let's face it, it's an old car with more than 200,000 miles, you're going to spend over a thousand dollars doing that kind of work if this stops it and you only have to pay 14 bucks every time you change an extra oil to pour this stuff into what the heck, especially in terms of a Toyota They

make

pretty good seals, they usually don't crack or break, they just wear down a bit and since these seals are an oil seal that has a spring inside it, the spring holds. the seal, so if the seal is not completely soft and flexible it will leak, but if this makes the rubber more flexible, the spring holding it in place will help retain it, which is why this works for seals, not oil seals , because a gasket like the one on an engine is bolted in place, it's just there and if it's worn out, it cracks and then starts leaking oil, let's say you had a side oil leak and it's a gasket, not an oil seal , just a gasket you can try to tighten but sometimes they shrink and tighten and don't leak or sometimes you tighten the leak even more if they are cracked and that breaks them completely, they leak, no sealant is going to fix that no You can put a sealant, for example. that will stop valve cover leaks because it is just a valve cover gasket, it is not an oil seal, but in this case it is the oil seals that are leaking, so why these seals oil leaks?

Unfortunately, there are only two reasons: one is if you buy a poorly made car and it has poorly made seals, they leak because they weren't made correctly and after so many hundreds, thousands or millions of rotations they just wear out and start leaking, but in the In the case of Toyotas, the main reason oil seals leak is because people don't change the oil enough, that's why you want to change the engine oil every 5,000 miles or fly once a year because the rlcs are made of rubber, right. I mean, GM tried some Teflon seals, but they didn't work.

They leak like a sieve and they all replaced them with normal rubber ones. Then you got the oil dirty, what is dirt? Dirt is friction like sandpaper, if it's dirty enough it's bad enough that that friction and dirt wears down the metal pistons in

your

engine which of course takes a really long time to wear them out, they're made of rubber and so What will happen to rubber when it has friction, it will wear much more than metal, so although you may think it's just an oil seal. It only costs 22 dollars, yes, but if you have to take out the engine or transmission to replace the seal, that 22 dollars will add up to a thousand or more in many places, it's a lot of work that you can avoid in the first place by simply changing oil regularly.

I say no, it's an old vehicle. I don't need to change the oil line if it leaks to burn oil. I'm just adding it. I still changed it. What do you think a 17 year old motorcycle is like? still works like a hood doesn't leak oil look at the shine no oil leaks no oil leaks on the floor my wife would get mad after i did a good floor and she is 17 because the oil has been changed regularly. Be careful, it goes very fast because it has been cared for and most importantly, if you do nothing in a vehicle other than put air in the tires when they are low, change the oil every 5,000 miles or so with full synthetic oil. that's a better oil, lubricates better, stays cleaner and of course if you live in northern climates it flows better so instead of having a car when I was young they had pure white oil, 10 wheels, 20 pesos , 30 pesos, 40 where it only weighed one peso. and if you had the summer white oil 40 in winter, you would raise the edge oh oh and it started.

Synthetic oils flow very well and I will be starting in the winter so there are many reasons why you would want to do this. they will

last

longer and you want to spend money fixing things it costs a fortune it would never have broken except you didn't change the oil enough just remember this its simple oil is cheap engines are expensive even changing a twenty rear engine dollars means The oil seal is expensive because you have to take out the engine or transmission to do the job. Why would you want to take the risk instead of just changing the oil?

The strangest thing is that of course it is more important to do it in an old car because the new car is new and the seals are new and of course they are going to seal better, but in an old car everything is old, you actually need to take better care of it. an older car than a newer one, so just Keep changing the oil every 5,000 miles, something cheap, do it yourself, if you can't find a place that does it for a reasonable price, you won't get ripped off, but as it stands today, everyone scams everyone, so even the oil change gaskets.

If you go to them they will try to sell you 50 things while they change your oil and they will sell you some bulk oil that is in a container that they buy cheap and I know a guy that has a discount oil business. You buy your oil filters for 99 cents a piece, right? Hey, do you know what 99 quality oil filters you want? So if you do it yourself, trust me, you'll save a lot of money in the long run and you won't have to worry about people trying to sell you a bunch of junk that you don't really need.

Now the drain plug will take two thousand miles to do its job. job, but we're only talking to the husband who owns this guy," she tells him. You need to keep adding a ton of oil. No tunnel oil leaks. There are only leaks. This is the infamous 2.4 liter Toyota engine that burns out because the piston rings are worn. All I have to do is take out a spark plug and remove the cap. turn off take out a spark plug first remove the coil take it off and we will check a spark plug we can see it burns a lot the ignition end is oily it burns a lot so it is burning will live with that my grandson has. a Camry same engine Burns oil, carries oil in the trunk and adds it every time you fill it, check it and then add whatever needs to be added, it's easy to do, but you're not going to rebuild an engine, an old car like this is not It is worth replacing the spark plug, replacing the coil, screwing it into place and replacing the beauty cover.

It's not very pretty anymore, but it's here, so we might as well put it back in and realize we'll just add a lot of oil to it, you live with it and don't rebuild the engine, but it can still run for a long time. I have to solve it. That stupid check engine light comes on. The owner of the Chevy took it to several places. They were told several stories: He went to an auto parts store that was selling the wrong part, so let's break it down the right way and figure out what the hell is going on here, so we'll bring out the big guns and not waste time on this. it will tell us everything we need to know and more and here we are going to start setting it up now you noticed when the check engine light came on your fuel consumption got worse so there is a reason to look into it there are hundreds of things that could be You never guess to use a scan tool and in this case I am using the top of the line scan tool because I am going to find everything that is wrong with this car and find out if someone was telling the truth or if everyone was stupid. we will do a smart diagnosis, it's like betting on a 2007 Chevy Colorado.

There it is, we will go to the diagnosis and do a full system scan, here we go, check that everything doesn't take too long and doesn't go through everything. the different systems check the report now we are doing the smart scan it will find what is good and what is bad and as it is color coded obviously red is bad green is good okay so we will start with the PCM it has a code. P0449 Evaporation Permit Evaporation Control Solenoid Ben, sir, that is a code for the EVAP system, something is happening with the vent solid it could be a badge vent solenoid, it could be wiring, but that won't actually do For the vehicle to malfunction at all, it's just an anti-pollution thing, so let's look at the other six codes here.

Well the electronic brake control module knew the ABS was malfunctioning and it has a code for the left front wheel speed sensor, right front wheel speed sensor, left front anti-lock brake. system channel on release too long it is taking too long to release the right front end as if the brake system was taking too long to release it lost thecommunication with the computer and lost communication with the body control module and the dash integration module, well we know the ABS didn't work and now we know it would probably cost a small fortune to get it working, I just realize You notice that the ABS is not working properly.

Drive normally. I only have one car that has abs. Not everyone else, so for me it wouldn't be like that. Well, now come the big boys, let's analyze the live data stream and try to figure out what's happening, why your gas mileage went down. We are seeing that the air fuel ratio of 14.7 to 1 is perfect and what is 14.70 to 1. so it is working fine, we know that it is not the engine coolant temperature that is the correct temperature. I knew I had an EVAP problem. It's probably a bad evaporative vent valve because the car is idling and when the car is idling it's not. supposedVent here says that the evaporator vent solenoid is commanding the vent, so it's only supposed to vent when the car is stopped, it goes to the charcoal canister, removes the hydrocarbons, and in theory the pure air at least comes out by the vent at the top, but now it is venting. when it's running, which it should never do, or there's an electronic problem commanding it when it shouldn't or the valve itself has gone bad, but that won't really make the thing malfunction, so let's keep looking now, for some reason , long-term.

The long term fuel trim is 7.81, so it adds 7.8 percent long term fuel, so for some reason the computer thinks the lean running vehicle doesn't have enough fuel, so it adds 7.8 percent fuel and that's enough to give you poor gas mileage. look at some more information now, here's another strange thing: the short term fuel trim while it's running, it's actually subtracting three percent point seven eight percent, so it's actually running rich at idle but at low and high speeds, let's speed it up a little and see how I accelerate. goes up and now it's adding fuel it's now zero but it's adding fuel and then subtracting fuel the short term fuel term shows what's happening right now the long term over time so long term it thinks it's running lean and it's adding fuel but its term is subtracting fuel, this is kind of a classic sign that the fuel injectors are a little dirty because it may seem crazy but a dirty fuel injector is supposed to form an inverted cone with a perfect shape to spray and atomize the fuel, let's say they are dirty, you might think that they are dirty they give less fuel, so you know it won't get rich when idling, but no, because if it's dirty, instead of spraying a good spray, the globs have too much fuel so it runs it rich because the Globs don't leak and it's running a little too rich so when I revved it it actually went the other way many times a dirty fuel injector will run just as well okay, let's take a look at this. our data we see if it ever fails now we're going to 80 88 cycles of misfire data.

I'll look at the history, the best ones are up to a certain amount, this is the total history and the total history shows two on cylinder number two, all others are zero, some reason cylinder number two has a history of two misfires, he's been in this since new, he's never changed the spark plugs, that's the Numero Uno thing, making a small amount of misfires. I've seen them where they have hundreds, this was just two, it's not much, but if they all wear out over time, they will wear out. It becomes cumulative and can start to give you worse gas mileage, especially when the gap starts to stretch, so I'll move all this p

last

ic crap out of the way and press my toe.

Now that we have some space, we'll check the spark plug guard. turn off the ignition coil and take out a spark plug, oh ok I have a spark plug to look at, worn plugs so you have new plugs and here's a warning, modern plugs are all coated you don't have to put any anti-grab on them if you do, they won't be right, so place them like this, glue them in now, you can use the torque wrench if you want, tie the fingers together, then put a ratchet on it, this is on and then move forward a little bit. that's perfect and I'll put the ignition coil back in and we'll do the other four, always change them all, don't be full.

I've only changed one already, unless you have a junky old engine where one cylinder is so worn it eats them. then you can change only one at a time, never forget to tighten the clamps because if you don't tighten them you will have an air leak, the mass air flow sensor measures the air coming in, if there are leaks, unmeasured air will come in. your car will run like shit, simple thing for Chuck, just make sure you have them tuned right, so let's look at it right now, people who know me well, no, I'm not a big GM fan, but this inline five engine in reality it is.

An excellent engine. I had a customer in Houston with over 350,000 miles on it and he burned a quart of oil about every 1200 miles, but that's not bad, this particular one still doesn't burn any oil, so they are not extremely powerful engines. but they could tow enough weight and can last a very long time. Let's test it on the road. Now you can see that the five-cylinder engine is running. They are engines with smooth idle. It's one of the reasons they made six cylinders and then I had some experimental fives for various companies and they all run pretty well now Audi made five cylinder engines for years that were famous for their smooth power bands.

There is nothing wrong with a five-cylinder engine. They were just never that popular. Now this truck has positive results. Rear-wheel drive and it's got that five-cylinder engine, let's see what it does on our little track here in a second, when this car gets out of the way, well, we'll have to go now, it's got decent thrust, it's a very good truck, so now you know in this case he needed spark plugs, people will try to sell you a lot of things, people told them all kinds of crazy things, they said you needed oxygen sensors, blah blah blah, he didn't need any of which now he doesn't cared about the ABS, three of the sensors have problems, ah, who will bother to fix it?

It stops well enough. Check engine lights are on because you have a leak in the evaporator. If it works well enough now and gets good enough gas mods, it will. leave the guide also scan tool a little information there are a lot of things you can fix on your car now you don't need a fancy one like mine that makes it a lot easier to cover all the bases even if you didn't have a scan tool, you never changed the spark plugs and they are the original spark plugs from a car that is 15 years old, so what the heck change the spark plugs?

It's not difficult, we have a Toyota Highland, it's running poorly and the woman. Whoever owns it is wondering if the work he's been paying for has been done yet, so let's check all that out. The first thing we're going to check is there's a bunch of lights on some of them, we don't care, but as we go to the back, you can hear that it's not working, hear the knocking, it's definitely failing, you see the light check engine flashes when it flashes, it means there is something relatively serious wrong, so I always start with a quick look, it is definitely shaking, no.

I don't have any vacuum lickers or anything, sometimes these hoses fall off but you can see they are still there. Don't take out the old computer now that you've had it for about eight years. You can see it has 258,000 miles on it, so we'll pull out the plug and plug it into the OBD socket and start analyzing. Has some wear. You can see that she is not a smoker, but the previous owner was the one who gave her the car. Drive a lot. That's how it is. I have all the mileage, but here we go, a misfire was detected on cylinder number one, so it's cylinder number one misfire, so we'll remove the beauty cover, which is silly anyway, in this case it's screwed on so we have to unscrew it, we really went all out with this so take off the beauty cover.

What we are going to do is change coil number one with another coil. Now, of course, you'll know it stinks because cylinder number one is hiding underneath. so we have to go in there and take it out, we're going to change the number one with the front here on the front there and see if the mess moves, so we'll do the easy thing first and take this coil. turn it off and remove it many times they stick so you move them hello now what we are going to do is change this coil so if the misfire moves from here to here we will know that it is a bad coil and we just have to replace the coil now there would be There was a lot of cursing and swearing to get it out, but the ladies were behind me, so I stopped that and now what we're going to do is put in a coil. from the front and back and the one that says it fails in the front if the failure moves well not only does it need a coil I just have to put it back because then the bad one is going to be in the front it will be real easy to change if that is the problem, here's a tip to get to the back and take it out.

There is a 10 milliliter bolt that you can't reach, but with one of these flex head wrenches you can reach it. The front ones are very easy. getting there doesn't matter, but the one in the back there is no room so you need one of these to turn it back on I have the ignition coil this is the one we think is bad that was at number one let's move it here what's happening and we'll plug it in the connector which is what holds it and now the first thing we are going to do is turn on the key, turn on the key and we will erase the code, now we have to do.

That's because it has the start code, we will make a race layer that will erase the codes, if we don't erase it, the code will still be there and will confuse it. You can see we threw it away, the codes were gone, so I'll start it now, you can see the check engine isn't on yet, but we're going to have to drive it and hopefully it'll come back and we'll see if it's gotten that far off the number. one that moves well, everything is getting ready to drive, but the check engine light came on flashing and went off and cylinder six pl306 number six failed, well we moved from one to six, so now the six is ​​confused, so we know it's just that the ignition coil doesn't shake anymore.

This again is of no use, but we're going to put it in anyway. Don't shave it for an old car with all this mileage. No, she. I wanted to check the tire so I'll get a tire gauge I'll check them let's check the tire pressure which is 28 check this one which is the same so far both were the same it's the same and the last one which is the same. Now that I look at them, they're not too old, that's not Roddy dry, that's not dry rotting, this one's not running dry and maybe there's this and I have a lot of junk now she drives a reasonable amount to church, like that who said he drives 12-14,000 miles a year, so that preserves everything too. it goes because you're using it all the time if you don't drive much it dry rots they will slide off the round spots because they sit there all the time but she drives us enough that there is absolutely nothing wrong with it tires A lot of people as they get older don't drive much and then the tires, although they look good, when you get closer you'll see cracks in them, they'll leak air and then you'll have to replace them, but they're still in good shape. in good condition, drives as many miles, they are not strangely worn, they still have the same amount of pressure so you don't have to worry because it is an older car, of course the tire pressure monitoring system no longer works.

It costs too much money to fix those things, but there is one more thing we can turn off. You can see that the magnets gained light, so let's turn it off, which is easy to do. Yeah, press the odometer reset and then turn the key on and you can see now it's ah, she said she's got a little bit of an oil leak so I'm going to check down here and we can see a little bit of seepage there, which is typical on these. things, it's not that bad because it hasn't even hit the ground yet, what is that, it's typical on these, you'll often have a small leak at the engine front main seal, you'll get close to 300,000 miles, you'll have a small leak here and there you're not going to tear up the engine to replace a main seal, that would be very difficult, it's not even leaking on the floor, but everyone does that and I looked the other way, the rear main seal has a small leak. a little bit and you live on that oil, it's cheap to take out an engine to change the seal costs a fortune so don't worry, like I said it's not even a magnet for the ground, they will typically look like this engine. and my last,you put your hand in there, yeah, so it's got a little bit of oil in it, but I mean, they all leak a little bit and it's going to hurt anything, it might be all old, it might have gotten here working poorly but it's working pretty well. just for a small ignition coil, did you ever think you had a bad one? you had a misfire change them just like I did it fixes it we're glad it wasn't the one in the back in the middle because that You have to pull the entire intake manifold to get to at least we were lucky it didn't Outside of that because it's a job to remove the back of the top of the engine in this case, there was enough room to get to number one. and change it and as you can see it may be old but I've seen it with 500,000 miles on it in Texas it still runs good after all these years and it was a simple fix so if you don't want to miss another one of my videos on new car repair remember to ring that doorbell
