Flywheel Cover Oil Leak?

Rear mains usually drip a little farther back and tend to oil the radius rod ball. The early blocks had no oiler hole from the valve chamber down to the rear cam bearing. Ford came out with a service bulletin to drill a hole down into the journal bore to allow better cam journal oiling. They did this due to excessive wear that was happening back there. All these engines are old now and many times the cam bores have to be align bored to install bushings in there to repair the off center wear that happens. Even the early V8 of mid 1932 had iron on iron journals for the cam. If the journals are restored with a new cam installed, the gasket will make the oil leak there go away until it all wears out again.

I've seen folks drill for screws and install a new thrust bearing back there as a repair but it depends on how bad the old babbitt is worn.
 
i'm having this issue as well.
i thought i was going to have my car mostly fixed up and ready for tour, until this started happening.
looks like another year of giving the insurance company money for almost no reason.

Is there any way to permanently stop this? i'm reading the posts, but theyre not exactly warm and fuzzy outlooks.
 
I have one here rite now the same. For mine I suspect there was too much end play and that movement destroyed the inner face of the Babbitt. Never the less it needs to come out.
 
My Burtz engine developed a leak at the rear cam opening so I bought a piece of carbon fiber gasket material that was rubberized and cut a new gasket. No more leaks! Also had to increase the thickness of the spacer shims at the accelerator ears to .015 because the new gasket was slightly thicker than the brown paper sack original

ell me more about this rubberised carbon fibre gasket material. I've never heard of it but if it works like you say, I'd use it in all of my engines (including my Burtz engine that has no O ring back there).
 
One advantage of positive crankcase ventilation is the negative pressure in the crankcase. That will eliminate or greatly reduce any annoying oil leaks. Of course it does not fix broken seals or other broken or bad parts.
 
Hello, I can say for certain there should be a gasket between engine and bell housing, one of my first Model A adventures back in the 1970,s wasn’t aware of the gasket, had to take engine back out to install it, remember that real well, air is probably still blue in Wesleyville!!!
