Since I am asking questions about the whole BEB thing, why not the use of Permatex vs custom gasket? I can't find any threads on why Toyota used Permatex as a gasket? Is there any good reason I wouldn't want to cut out a piece of cork or gasket material instead? I hate the idea of Permatex squeezing out into the oil pan and making its way into a 1/16" oil passage. I know I am going to be careful and not use too much, but it is kind of inevitable it will squeeze in there a little. I just scraped out a ton that was on the inside from the factory. I know once it cures it really won't be an issue, but I would still feel better with a gasket.
