Leaky Intake

I have a 350 with an aluminim Edelbrock intake manifold. It leaks a little bit of oil around some of the intake bolts. Anyone know how to correct this? All of the proper gaskets and materials were used when we installed it on the motor. And we've rechecked all the bolts to make sure they are still in tight and with the right torque.

gm says put liquid teflon paste or equivalent on intake bolts

I'm new to this but I"ll see if it works....
Putting a little permatex on the manifold bolts works well (I like the brush on type myself).
You might want to check your PCV valve also, you could be building excess crankcase pressure if it"s plugged.
