What happens if you....

[NgoFcukinWay]

put a li'l more motor oil than you need into an engine?

a friend of mine put about half a quart to a full quart extra into his car, and after a bit of driving, smoke started to seep out from under the hood?

 

[boost fiend]

having 1 extra quart in your engine isnt a bad thing. lots of people do it. there might be a leak somewhere.

Hubby over filled my engine a long time ago by about 1 qt. I was out later in the day doing some spirited driving and I also noticed smoke coming from under the hood. I immediately pulled over, but before I even opened the hood I knew what it was. Oil was pouring from the cam seals. The high pressure blew them both out.

It could have been a coincidence, that the seals were old and needed to be changed anyway, but I always make sure my oil is never overfilled now.

was told in autotech that is the oil level is to high that the crank could churn the oil up into foam which would then get sucked into the oil pickup and could then cause something like rodknock because of the air mixed into the oil.

i dont think one qt. over will do this. wanna have some fun? do a search for "15qts" you'll find a thread by Pioneer who took a bunch of pics of a motor that was filled with 15 qts of oil, all messed up.

Some interesting stories. I'll keep the oil thing in mind. As for my friend, I found where his "leak" and smoke was coming from when he popped his hood. He forgot to put the oil cap back on, so some of the smoke came from there. Thanks for the helps though guys. I'll keep this thread going if any other problem comes up over this "1 qt over" deal.

There is no real correlation between Volume Vs Pressure Tanya so it had to be coincidence.

7M can easily get away with +1qt as it doesn't bring the Oil level anywhere near the crank while running.

i run 1 to 1 and a half extra now and no problems here...

it must be the color j/p

 

[GrimJack]

I always run one quart over.

Last time I rebuilt the engine, I deliberately didn't put the dipstick tube all the way back into the block, so the guys at the oil change places are always confused when it takes an extra litre over what the manual says to get it to the full mark.

From my understandings, and I may be wrong, 7Ms oil pressure is lower than the 5Ms (which makes no sense to me) and I also believe my pump was shimmed at some point. Either way, I keep her at factory specs, but can totally understand running 1 over in a 7M, although I think shimming the pump would be a better solution IMO (but then I'm a turbo dummy so don't listen to me)

Tanya: My point is even shimmed and in a high pressure system adding more volume to the pan wouldn't increase pressure so yours had to be one of those freak Toyota coincidences!

Shimmed pump in a 7M and stock level you run the risk of pumping the Pan dry if you're into it for a long time!

and IJ takes the win!

remeber, as soon as you start the engine, the oil starts moving from the oil pan to the top of the engine (and to the turbo if your gte). so, being 1 qt over really wont matter to much.

eh but thats not really the point. that point is that in the 7m SPECIFICALLY, there is enough room for an extra quart without having the oil level getting too close to the crank.

this is not true for every motor however, it depends entirely on the engine.

Agreed!

I used to drive a 572 Cu In bigblock blower motored 1978 Pro-Street Monte Carlo.

I had an extended oil pan like this one:

and relocated dual 2 qt capacity filters that looked something like this (except it wasn't a bypass system, just standard filters):

As a goof I took it to an oil change shop once just to see the guys freak when they found out it took TWELVE quarts of oil to fill the system. '

Manditory on topic comment: Yes the 7M can easily support an extra quart without getting into the crank.

Mike: LOL I run a GrpA Magnesium pan a 3 qt accumulator and a remote filter so it holds around about the same as your BBC!
(Don't think I'd trust a lube place to change the oil though )
