[double ugly]

I've decided to pull the intake manifold and replace the gaskets along with the valve cover gaskets. This will take a lot less time than removing the interior to get the tranny etc. out to check the galley plugs. (many people have told me that it is fairly rare for them to leak the quantity required to cause my problem). I've already wasted the money to have the rear main replaced so I've decided this is the next step. The gaskets are cork not a silicone smear but it seems like a logical next step. I did notice that the left and right sides at the rear of the intake gasket are a translusent grey/black. This may indicate a leak. I'm really surprised that the black light didn't show any thing there though. Again thanks for all your advice as the saga continues.
