LOL... youre complaining about sealing surfaces needing to be impeccably clean of oil? That is a prerequisite for ANY gasket...or did you think that even your favorite honda silicone was going to stick to grease? And as for the clean room comment, thats what I use to seal Porsche engine blocks, and you better believe everything is spotless.

Thats actually really good silicone, I'm not sure why you dont like it. I usually clean the surfaces with a Mirlon scuff pad ( the red one is very fine and doesnt leave any scratches ) and then take rubbing alcohol or brake cleaner, soak a rag with it, and go along the sealing surface until its oil free.

And please dont lay that silicone on too thick, just a bead maybe 1.5mm thick is plenty. Remember that the excess ends up in the oil pump feed strainer....

As for regular stuff? I use Permatex's "the right stuff"
