I'm working on a small block chevy and I put an aluminum intake manifold on it. I used Mr. Gasket Ultra-Seal Intake Manifold Gaskets made out of the cellulose nitrile crap. Paper in other words. At any rate, I've got this beast running and it seems to run good without any noticeable leaks. No milkshake oil. No noticeable coolant loss. I torqued it correct following the proper sequence. Re-did it the next day and even checked it since. But as I look at the portion of the gaskets that stick out between the intake manifold and the heads, I can see that they are saturated with oil. NOT LEAKING. No pooling oil......just the gaskets are saturated with oil. This actually happened over a few days and a few trips round the block warming the engine up and letting it cool. I saw the oil creep up the gasket from the base of the intake until it's now covered the entire exposed portion of the gasket. Now this is my question: Is this normal, or should those gaskets remain dry looking? I've never used this type of gasket before.
