What actually happens when you overfill your motor oil? (w/ transparent oil pan)

Hi, Fells people often wonder

what

would happen if you filled the engine with twice as much oil as it needs or even more. Anyway, we have an engine, so let's find the answer to that very question. Let's do this one more time. Look

what

we have. Got here guys, this engine is a factory original unit. We've cut out a window and moved the exhaust manifold out of the way so we can have a clear view. Now we just need to hit the discharge system so that the So that the oil is nice and clean for better visibility, so we'll replace this normal sump with one made of plastic and we should be golden.

We will start by giving the engine a wash. Look at this. We have everything assembled. The oil pan. is there, now we will be able to see how much oil we have there and have a clear view of the internal processes. We will start by putting the required amount of oil, then we start the engine and see what

happens

to the oil, okay, so the oil is at the maximum level, it reaches here, okay, let's start by simply turning the engine, we will see how the pump performs its functions, how quickly it collects the oil and we will see what.

happens

with the level, come on, so the oil level has started to go down and here we see it returning to the pan, you can know exactly how much the level has gone down, the pump has collected a certain amount of oil, it was transported upstairs to lubricate. the cam and the crankshaft and only once there was a surplus it started to drip down, the level has gone down, but if we wait a bit you can see that it is slowly dripping and will soon return to the baseline.

Well then. We have seen that the oil circulates only with the starter

motor

running. Now let's start the engine. Let's look at how the oil circulates. The oil level has dropped dramatically. The pump is spinning much faster. It is collecting a lot of oil and the ladder is not. find

your

way down quickly enough, yes there is only a little bit of oil left in the pan, there is hardly any, the important thing is that the oil catcher is surrounded by oil, so there is more than enough to suck up and no oil . hot enough, it takes longer to drip, it's still a little thick, that's not much, let's see what happens

when

we turn up the revs, let's see what's happening, the pumping has intensified and although the reducing valve is doing its job. but the oil level has plummeted, we have collected more oil and put it back down, it has started to foam, bubbles have formed, nothing too horrible though and now that we have closed this, the oil level is coming back slowly back to where it was initially. to where it was after we poured it now I suggest we double the amount of oil we'll check the dipstick to see the difference between minimum and maximum and that's exactly come on so look at this we've poured a little bit. new oil twice as much as required and you can definitely see the difference, the oil pan is almost completely full and I suggest we start this by simply cranking the engine using the starter

motor

, let's take a look, yes we are definitely at the limit here.

No, there was no contact even though it is very close, it is with double and let's try to start it, it idles very well, yes, the oil level has decreased, the gap between the oil and the crank has increased for all the people who They worry that something might happen. goes wrong, I mean, yes, the engine is stopped in the same position, it doesn't move at all, but even if you changed the engine, there is more than enough room for the oil to splash in any given direction, because if I can reiterate there There is a ton of space between the crank and the engine oil pool and the oil level continues to drop, so this is pretty interesting, you can see it clearly, can you see the oil jumping like it's trying to find its way in? the motor? block at this point we have established that nothing bad happens

when

the amount of oil in the sump is doubled, but we are not done yet, let's add a little more oil, so this is the situation: we were at the limit and everything we did.

It was at about another 700g and we can clearly see that the crankshaft counterweights are slightly submerged in the oil, also the bolts that secure the main crankshaft caps are greased and there is only one way to know what comes out of all this. We want to give the engine a spin and we see that oil is being sprayed on the block, it is not evacuating, the crankshaft is lifting it and splashing it, yes, it is completely soaked in engine oil, no friend, it's okay, so at a speed of We are so low on the engine.

By witnessing the simple process in which the crankshaft picks up the oil and distributes it throughout the block, there are no adverse effects to report, the picture is more or less the same as when we had double the required amount of oil, somewhere moment the crankshaft expels the oil and no longer comes into contact with it now. I suggest that we

actually

go further and add a little more oil so that the crankshaft is literally covered in engine oil, so let's do that and see what happens from there. No, let's do this. There is a ridiculous situation. amount of oil inside the engine, I mean the bearing caps are submerged at this point, okay, come on, yeah, as you can see the oil is splashing like crazy, it's all due to the crankshaft and connecting rods being They sink much deeper than before they splashed.

There's more oil around, yes, now it's really splashing. Look the crank is literally submerged in the oil and you can see air bubbles developing and some quite large ones. You also have an endless stream of oil splashing around the block. Yes, it's

actually

bubbling. All you can see really, but let's turn up the revs, there's the and so what do we see? There is a lot more foaming and we have more oil splashing on the engine block and you can tell that the crank can no longer expel the oil. it's actually scooping it up, it's scooping up a ton of oil, throwing it out and as a result we can't see anything.

Hey, at least we can see it splash and you'll notice that the engine operation has become a little less stable. at idle go get more oil look at this guys things have gotten interesting you can see the oil goes up to this little window yeah at this point the oil level is crazy there's too much in there for the good of this engine, but let's give the engine a spin without starting it and see what happens, yes the whale level is too high, the engine block fills immediately and you can't see anything. Oh, it started out great, but now you understand. the impression that the entire engine block is full of oil, I mean it is literally filling the entire engine block, you don't see any empty spaces and that's pretty good.

Anyway, we can clearly see that everything is filled with a whale, everything is fine. but let's increase the revolutions, let's be curious to see what happens. It says if we fill this engine with milk instead of engine oil and we have oil coming out of the breather, I mean, the engine is overflowing, you even have it spilling with the engine idling. some gas yeah bro is a full blown geyser so here's what's going on guys the oil level is actually above the center line of the crankshaft which means the entire crank, the stumps and so on, everything is submerged.

I suspect we are looking at a total amount of over 12 lers but we won't stop just yet, let's move on, oh that's just lovely, the engine doesn't care how much oil is in the crankcase, it's running even though it's an ID Does it really work? to keep it running check we have a leak somewhere no it's just I'm looking at this cool Vortex anyway we've stuck the breather tube in a container and now I guess we're trying to make it run like an old diesel. producing a lot of smoke which is not good at all what is the problem we have an oil leak but that is not a surprise because well, instead of crankcase gases there was liquid oil circulating in the ventilation system, we saw some spit from the pipe, but The engine still starts and runs, and that's fantastic, I take my hat off to this thing, and while the engine was running, which didn't last that long, it wasn't more than a minute, maybe I would say, and we have a good leader inside. this jug and there's more in the container, just like I said, there's no crankcase vent right now, it's just engine oil circulating, but let's pour this back in and increase the level even more.

What do we have here? I see that it is better not to touch it, so look guys, at this point you remove the dipstick and immediately oil comes out, no one in their right mind will pour that much oil, but for the sake of the experiment so far we have established that when the oil is At the normal level, everything goes into the engine when it starts twice,

overfill

ing is not a big deal. Three nothing terrible is happening either, but now we are as high as possible and now let's try to start it, it works, that's fine, but we have a leak and given the situation we better give it some gas while we can it's a massive leak, it will be soon yeah this is crazy man I better stop squirting oil oh yeah I'm gonna need a rag get out the flashlight yeah yeah please do it everywhere it's good for rust protection tho It is very good to get the power units out of here and here is the situation: the

transparent

plastic oil pan has abandoned the point is that it is leaking a lot of oil and therefore the oil has found a weak point. with the amount of excess oil we have there, if it happens that you poured in a little bit more oil than required, while in reality there is nothing to worry about, so you saw it all, that's all I have for us to see later.
