Default Oil leaking from distributor cap

Ive been searching for the oil leak in my car and after hours, finally
found it. I don't know much about distributors but there seems
to be oil-yes oil, leaking from the distributor cap. I took it all off
and cleaned the cap,rotor and o-ring really good and its still leaking.
Like i said,,,"dont know anything about distributors" Is there even
supposed to be any oil in there????


Thanx for all the advice recently guys

Oil can, in fact, leak into a distributor, and no, it's not supposed to be in there. Distributors have a seal between the shaft and housing, and it's likely that the seal has failed on your car. Also, I'll offer the usual suggestion that the leak could also be caused by positive pressure inside the engine... meaning the PCV system is clogged. Do the usual checks for a clogged PCV system (moisture/ condensation on dipstick or oil cap, smoke blowing from dipstick tube with engine running, and replace the PCV system if the checks come up positive. Otherwise, you'll need a new distributor.

FCPGroton sells the kit, and there's a good diagram as the illustration for the kit. You'll also find instructions in the forums. Here's the thing- it's not the easiest job there is to do (not the hardest, either) so make sure your skills and tools are up to the job before you begin. One step which is overlooked a lot is cleaning the port where the oil trap connects to the block. And make sure you change the oil when you're done- run the engine for a few minutes after completion, then do an oil change.

I assume you mean that oil is splashing out of the dipstick, right? You'll only see smoke with a running, completely warm engine, but it SHOULD be there if the PCV is plugged.

Default Definite pcv clog

Okay, replaced the rear cam seal. took me about an hour cause
ive never done it before. sealed right up, no more oil comin out
of the dist. cap. NOW, a good amount of smoke started coming
out of the TAILPIPE? and also coming out of the dipstick. My first
thought is that with no oil leak, there is more pressure in the
engine now right? so now I guess pcv system needs changing.

yup... sounds about right. Fix one leak, pressure builds up... it's like trying to plug a failing dam. So... get that PCV taken care of, because replacing a blown- out rear main seal is a LOT more expensive than the PCV system...
