i have an 88 turbo II and I have an oil leak (clean oil) and i have narrowed it down to the area near the oil drain plug hole but it looks like its comming from above but im not sure were. it only drips a little, a small drop or 2 after it has been significantly warmed up (driving for a while). any ideas of what could be the source? thanks.

 

Try checking out your rear oil cooler line. Sounds like it might be coming from there.

 

Completely degrease the engine, then start it up and let it idle. Carefully look around the suspected area to find the leak. Oil leaks often start ABOVE the area where you think it's leaking, so keep that in mind. Once you have found the leak, fix it.
