Thank you.


Unless your engine is puking oil out of the cam chest breather/air cleaner or the main seals when starting up, you don't have a problem worth worrying about. Some amount of oil in the crankcase after sitting for a time is inevitable. Drainback from the heads and cam chest alone could be many ounces. Even with a quart or so in the crankcase, the scavenge side of the pump will rapidly clear it (back to the oil tank) likely by the time the engine starts.




Yes, I have both main front pinion seal leaking and camchest puke and this is the reason I am asking the questions. Making the oil tank breathe helped but not totally stopped it.
