Default chasing oil leak

I need some guidance.

I recently put in a new clutch in my 1985 GT and the reason for failure was oil on the clutch. I assumed at the time that it was cause by 1 of 2 things...either the rear main seal or the oil was coming through the through-threaded holes on the crank. So while i had everything out i replaced the seal and put permatex #2 on the threads. So now about 2 months later i was under the car doing some exhaust work and noticed oil on the bottom of the plate between the bellhousing and the block. I took off the inspection cover on the side of the bellhousing and there is oil all over the place. I think the oil is coming from above the bellhousing somewhere and draining down because the tranny is all oil and I remember seeing some oil near the top-end when i had the tranny out, but dismissed it because the motor was/is pretty old and dirty. So without droping the transmission to investigate does anyone have any ideas on what's going on?... Is it typical of a certain type of leak? Also, oddly the clutch is still grabbing great, but If i don't take care of the oil I assume it will fail again, or maybe its too late for this clutch too.

Sorry for the long post. Thanks for the help.

Maybe the back of your intake manifold or you valve covers are leaking?

maybe it's your valve cover? wash the engine down with simple gren will make it easier to find ..if you still can't find it then try some dye in the oil

I talked to a friend and he mentioned the back of the intake manifold as being a problem area for leaks. Is this a pretty classic place to have problem? I think that must be it but while I have the top end apart i will probly do the rocker cover gaskets too. Any recommendations on what brand or type to use? I usually go with fel-pro.

Thanks for all the help.

P.S. Do you think i can save the oiled clutch? anything i can do short of replacing it?

Look for some rubber gaskets. I've got some on the car I just bought and they're great. I used them on my old car too and they were much more forgiving than cork.

You know where you got them? I can't seem to find any. Fel-pro only had cork ones on their web site and ford racing had cork ones as well. Also, the rocker cover gaskets are perfect so i was wondering if i need to take them off to get the intake off? If i don't it would be great.

don't use cork as if soaks up oil ..either buy a reuseable gasket which needs no pretex of use a metal one with rubber on the outside
