my problem is the oil leak from the inside of the distributor and came outof the distributor cap. i check the everything on the distributor and the o-ring, everything still finenothing wrong,butit keep leak oil. The caris run good andi don't know what going on it....i though was head gasket wasbadbut not the head gasket and i saw oil came from the distributor cap.anybody can helpme out

 

there is an oil ring on the distributor shaft;
may be that or may be coming from around the area of the dist off of the valve cover (gasket)

 

what he said, buy a new o ring at your local parts store. ask for a "distributor o ring"

 

I just had the same problem and replaced the o ring and now no leak!
