Hi. I recently diagnosed an oil leak in the 94 LT1...what a suprise. Anyway, my mechanic said that it is coming from somewhere in the back of my engine. Now, other than the rear main seal...what other gaskets or how many other gaskets are in the rear of the engine?? I am going to try to find fel-pro gaskets and have him change them all out at once. Please help....

 

the intake manifold leak. It's fairly common. remove the intake replace the intake gaskets and lay some thick *** bead's of rtv on the back of the block there is a large gap..

 

That or even the valve cover gasket.
I had oil leaking down the back because it wasn't installed correctly.

 

same here intake manofold leak

 

Ditto

 

i got intake and valve cover leaks.. valve cover gaskets are like 20 bucks i think intake gaskets were another 20 then rtv is like 3-4. my mechanic wanted like 200 bucks to fix the intake leak so i just sucked it up and did it myself it wasnt that bad once i took the fuel rail off.
