My 258 is leaking oil where the dipstick holder enters the block, and also around the base of the distributor. I fixed the leaky valve cover and now I can see these leaks. They have probably been leaking for a while. I am considering an O-ring for the distributor. Anyone know the base diameter? Not sure what to do on the dipstick, it is really loose where it enters the block. On other 258s I have had to use a hammer to get them out. I am sure others have these same leaks give me some ideas.

Later,
Tom
