Oil leaking from rocker cover

[Elwood]

Thanks, but not the case. I checked the PCV and it is fine. I cleaned it anyway. There was a definite vacuum at the oil fill opening in the rocker cover....

[Elwood]

THANKS Ken. You were right, again....

[Elwood]

SOLVED!!!! The simplest possible solution solved the issue, a new gasket in the filler cap did the trick.

[Elwood]

Thank you. I have those, the old ones had deteriorated but I put new ones on with no change. I appreciate the suggestion....

Dick, I replaced the old sealing washers for the hold down nuts with new ones but that did not help. I took off the PCV valve and confirmed it was neither...

Brad, in this world of SUVs, Minivans, and distracted drivers, our little cars need all the help they can get....

Mine was rebuilt in 2016. Compression is great, I'm going to borrow a leak down tester next. When I drive around town, nothing comes out. It's only after...

Bruce, I've had this one since the mid 80's, and it didn't leak anything until last month....

[Elwood]

Does this tell you what you need to know Bruce?...

[Elwood]

Thanks Ken. That's the plan....

My engine recently started leaking oil from the top of the aluminum rocker cover. It seems to be coming out of the vent hole in the cap, or the cap gasket....
