A friend gave me a 361 that he replaced with a 383 because it was suffering from low oil pressure. Pulled it apart and found that silicone was used liberally on it instead of gaskets. Found strings & chunks of various colored silicone sucked up into the oil pickup clogging it up. I am sure it did not happen all at one time, but over the years. Silicone cost him the price of and the labor of replacing an engine. Now that said, a thin layer of silicone on both sides of a gasket can help the sealing process in extreme circumstances.

Eric I've found that silicone is great in the bathroom, around sinks, and for caluking doors and windows on a house. I've found very little use for it in my car. Clean, straight surfaces with good gaskets that are properly torqued have always worked very well for me.
