ball bearing fall apart in an aftermarket turbo?
Not saying you're wrong because I don't know, but if those are in the egr valve I am buying an egr delete right now.I can't think of anywhere that the ball bearing could get introduced to the heads? did someone sabotage it? the egr valve? does it have a ball bearings or steal balls of some sort inside it? that's the only thing mechanical on that side of the engine in the intake tract that could allow something in there isn't it?
