The level of anxiety i go through when overfilling my engine just a little over the max level, thinking it's gonna explode any moment, this guy is a hero

@greymillan5697 28 күн бұрын

Engine companys always have and extra space for this cases. The max level its below the real max till start to make foam at oil. Try to keep between those levels but it you fill it too much, doesnt matter. If its toooooo much, a syringe of the biggers ones and a flexible pipe that fits the tip of the syringe and you got it, without draining with the drain plug.

Just remember this is a very simple , old school engine. Newer engines have more going on in them with smaller tolerances, so it would be still inadvisable to overfill any modern engine

@SkorpyoTFC 28 күн бұрын

For those who are looking for a problem and not seeing it, the problem is the foaming. As the oil level rises, the oil foams more violently, and this introduces air pockets to bearing surfaces inside the engine. On top of that, aerating the oil pump lowers functional oil pressure by introducing compressible air into otherwise non-compressible fluid, and makes it harder for the pump to maintain a prime while operating.

@butterflywoodworks2374 28 күн бұрын

With no windage tray in the pan I was wondering if foaming was going to be an issue.

@cmawhz 11 күн бұрын

few points to keep in mind here. first of all that oil pan is molded from the outside making it bigger than the original. this is an old lada engine, nowhere near the tolerances of modern stuff. it is only running for a few minutes in these conditions. it is not moving around like a vehicle going up/downhill. and they are filling it up even after it is beyond critical levels for normal operation. in my career i have seen a few vehicles towed into the shop due to double filled oil. one because the lube tech drained the transmission on a subaru thinking it was the engine and didn't check the dipstick after filling the engine with more oil. that car made it about a mile before it started bucking like a horse and pouring smoke and oil out of the exhaust. another one was because a chevy trax owner thought the oil life % on the instrument cluster measured the oil level, and put 4 more quarts into the engine when it reached 5% and dinged at them. that one was just pouring a bunch of smoke and oil out of the exhaust. besides that i have seen some vehicles shoot the dipstick out, spray oil onto the exhaust manifold, and clogging the catalytic converters just from being a quart or two over.

@fredrickdavenport1611 28 күн бұрын

2 things happen. 1. power is reduced due to the crank hitting the oil and picking it up. This is the reason race engines use dry sump systems or windage trays and scrapers. 2. The foaming action of the oil is increased not allowing air to dissipate out of the oil causing cavitation around the oil pump pick up tube, thus reducing oil pressure because of air in the system which reduces the film of oil on the bearings and causing extern wear. Garage 54 is what hot-rodding in the US use to be! Great and fun channel.

Wonder what would happen if engine totally drained again then refilled to normal level, would engine be fine again...? (after also replacing blown gaskets and such, of course). I wonder...

@EShirako 25 күн бұрын

@@gregpohl412 If the engine doesn't get too badly-beaten and the main gaskets don't rupture something, and if the piston rings don't get damaged from playing oil-wall-pump or whatever...yeah, when you return it to normal oil levels, any excess should find its way out of the system over time and it should GENERALLY be okay. Turbos could suffer terribly from foamed oil, as could the motor if it gets pushed to high loads/high RPM with the overfilled oil, but by and large if you don't run it for too long and don't have it explode out of something, it SHOULD mostly be okay. It might sneak into the pistons though, maybe they might need cleaned out, or the spark plugs might want to be washed/replaced, dunno. Mostly it should be fine if it didn't get pushed TOO hard before it was corrected. Put in FIVE times the oil, or fill it to where the pistons can't keep oil out and you could 'hydro-lock' the engine with the excess oil, and THAT would be terri-bad for the motor. They don't like 'stopping when one piston runs into the wall called "Oil can't be compressed" and stops the motor mid-rotation. It's like stopping it by dropping a bolt into the piston. CLONK, just using oil as the bolt.

A buddy of mine had a Trailblazer with a 5.3 V8 engine. Those engines are notorious for the O-ring going bad at the top of the pick-up tube. It happens to be at the front of the engine, so during acceleration or on an incline, oil pressure would drop, since oil moves backward in those situations. We put a scanner on there that told us the realtime oil pressure in psi, then we jacked the front of the car up until pressure started to drop. We added an additional quart of oil to get the pressure back to normal, then we jacked it up some more until it dropped again. We added a second extra quart, then jacked it up again, and this time it was high enough that we didn't think the car would ever get on an incline that steep. We added the third extra quart to get the pressure back to normal. After that, we simply added the 3 additional quarts at every oil change. That was a long term test of about 70k miles for a total of 230k on the vehicle when he finally sold it. As long as that O-ring was submerged, it couldn't draw any air and the pressure stayed normal. That was only 3 quarts over full, and it was a bigger engine so I never expected any adverse effects. We could have dropped the front axle, pulled the pan and replaced that O-ring, but to add 3 quarts and get the exact same result just made sense. Apologies to all the OCD mechanics out there scoffing at the "rigged" fix, lol.

I got unlucky then. Brand new car engine seized due to overfill. I didn't find the need to check since I it was a brand new car. Damage was done after 9k when I saw smoke pouring out behind going up a hill and afterwards saw that it was massively overfilled. Thankfully warranty kicked in since it wasn't my fault. They said with the newer engines everything is tighter so it killed it.

It truly depend on the engine design, oil pan capacity and the method of storing the oil (dry sump). Some engine have higher tolerance above the "max" mark while other engines may have a tolerance of less than 1L It is also good to note this engine was not moving like in a car. While braking or accelerating the oil get slushed around, at x2 the maximum the oil could have easily found it's way in the breather. It is best not to put in too much above the maximum.

A&P mechanic here. You’ll almost never find a dry sump land vehicle that doesn’t have the Ferrari Lamborghini Mercedes AMG ect logo on it. Most cars can’t even corner hard enough to starve the pump so most cars are wet sump. Now in aviation, for piston type aircraft, dry sump is the norm. So really you aren’t going to even need the wet sump dry sump variable because most people can’t afford a car that needs to have a dry sump in the first place.

I picked it up cheap probably because the previous owner thought it was a leaker. The oil coated the firewall and had blown all over the undercarriage pretty much rustproofing the whole underside. I put in the correct dipstick, my father and I put on newer heads that could handle unleaded gas and an RV cam that gave more bottom end torque. It always ran great even when over filled with oil.
