Do you even understand how silly the concept is ? that if you run too much lubrication thru a open bearing that your going to somehow blow it out ? like there is some sort of magical seal in the bearing and too much fuel inside the engine is going to create so much hydraulic pressure that it blows the seal out of the bearing ?

on engines that I block the bypass they leak out the bearing like crazy, yet no dirt ever gets in.......in fact as long as its leaking I know there is enough fuel to seal the engine and it wont be sucking in dirt...sucking in dirt comes from the ring seal running dry and being unable to maintain its seal..........100% opposite of what you guys are telling people ! your telling people being rich kills bearings when in fact its being lean that kills the bearing..being lean is what causes a engine to suck dirt thru the nose
