Oh, I thought you were referring to aviation silicone or something.
I can honestly say that with the engines that I've torn down and freshened up, I've never found any RTV anywhere in them, or in the filter after a dyno run. I use it pretty sparingly though, not in big globs, but in thin coats. I use it on freeze plugs,
oil pan end gaskets, around water jackets on heads/intakes, etc.
I also like using "The Right Stuff" to make up intake manifold end gaskets. That's about the only place I use it though as if you use it on
oil pans, you about destroy the pan trying to get it back off....
