Hey Jim, fraid to say so, but you're definitely blowing oil when cold under start up. I have the same FBF pistons and when cold they're slightly undersized. Having oil blow through the pistons like that is actually good for the engine and several popular motors do it, including my Audi TT. Maybe you just havenae noticed it because your pipes are not using the high mounts, talking to micha at MI, every FBF kit he's done has blown oil slightly when cold.
