Actually those intake gaskets do occasionally see oil. The oil tank is vented to the intake system and sometimes oil can be spit into the intake quite easily- slight overfill of oil tank or just simply oil vapor.

Not saying I recommend oiling the gaskets. Just saying that they do by nature tend to get oil on them and are intended to be oil resistant.

I like Jamie's idea of silicone paste. Makes for clean removal in the future and lessens the need to use nasty stuff like MEK. That stuff is effective but mucho bad for your health!
