Maybe I will trailer the F-100 out and take it to the Gateway strip.

...question from a dummy?
Hey guys, got a stupid question? I have a pretty fresh rebuilt 390 (about 3000 miles on it) and I am starting to see an oil spot in front of the engine where the intake and cylinder heads meet. It's not a runing kind of leak, just a residual type of situation. For all those 'engine-heads' that have rebuilt 1000 engines, should I just clean it off and keep on trucking? Or should I even be worried about it?
Hey, I have to ask these questions, I am a newbie seeking guidance. Thanks. Doc.
P.S. I guess I should give some more information about the engine that would provide for a better look at the situation.
10:1 compression, forged pistons.

I agree with fordman Doc. Unless it is getting pretty annoying I would give it an occasional wipe every now and then. The cork gaskets were probably used with the intake. They for a reason unknown to me leak like crazy. I tried several times to get mine to quit but I finally did it right (like edelbrock tells us to) and used a bead of blue RTV instead. No more leak.

Thanks guys, I won't worry about it then. The machinist did use to cork gasket that came with the gasket set. He suggeste I use Permatek on the headers though. Man, they stay tight for a while, then tah, tah, tah, you know the sound I am talking about if you have leaking headers. Thanks again, Rat, when are we going to meet up dude? I would like to salivate over your truck, haha.

i have some oil residue with rtv stuff but i not to bad. I have about 4000 miles on my rebuild. I was told that if you have your air cleaner on and punch on your fe when its cold you can blow the cork gaskets right out. But thats what i heard!
