Reply to "Exhaust Smoke"

Hello guys,
I was trying to kill three birds with one stone by installing a new intake manifold. The way my engine has been smoking, I figured I had some how blown out another intake gasket. Not wanting to pull the intake just to replace gaskets again, I decided to buy the Blue Thunder intake. I also had an oil leak at the front of the engine, apparently where the intake and the block meet. Maybe I didn't use enough silicone last time. By purchasing the new intake, I am hoping that maybe I can find some of that horsepower I have been looking for. So, today I removed the Performer intake fully expecting to find bad gaskets. Surprisingly to me, the gaskets look pretty good, not perfect, the blue part of the Fel-Pro gasket has small cracks in a couple of places, but I'm thinking about re-using them? What I did find was oil. It looks like all the intake ports on the heads are oily. The back side of the valves look bad, caked with oil residue? It looks like the intake manifold is oily inside, which now makes me wonder if it is the fuel pump that is causing me the smoke/oil problem? If I do in fact have oil in the intake manifold, is there any way for it to get there other than thru a bad fuel pump?
