My Yota has a slow oil leak. Any ideas as to the cause? How do I find where? Thanks.

 

Where is the oil puddling? Valve cover gaskets, rear main seal, are good bets. Everyone probably needs a bit more information to help.

 

oil filter ?

 

engine? and location of where you see the oil? pics are helpful.

 

degrease the hell out of it and see were it leaks

 

x 2.
Run your engine up to operating temp, and soak it down in degreaser and let it sit about 10-15 mins and hose it off, and see where you see oil first over the next couple of days.

 

Cool thanks I'll try that.

 

if your truck is so equipped with one, check your oil cooler...looks to me like that seems to be a pretty frequent area where we get leaks. this all depending on if your engine is a 3vze or not, that i was just assuming.

 

Mine were valve cover gaskets, leaking down the back of the engine

 

My oil leaks were from the two most hated parts... Timing cover gasket, and oil pan gasket. Definitely a PITA.

 

my leak was underneath and i degreased everything and found out the oil drain plug has a slight leak and blowing back, guess my next oil change i will install a new one
