Thinking out loud—wouldn’t that cause your throttle body and idle control valve to quickly become covered in crankcase nastiness?For now I am running it to atmosphere just because I would like to see if nothing else got damaged from the incident. I would like to try to put it back into the system in between maf and the throttle body. I think it would work. But so far so good going on 2 weeks now with no oil spray.
Water from the weep hole would mean the pump shaft seal is bad. Maybe try the BMW-branded pump?On a side note ever since I rebuilt the engine I’ve had water pump issues. I used original one when I first rebuilt it had no issues, but it scared me to run it because of how old it was, got a graf, coolant came out of the weap hole, warranted it, and same thing. Got a Stewart water pump and same thing. I’ve bled the system properly, like with the key on and jacked up the drivers side and let the bubbles come out and everything. Any ideas?
Defective new parts happen but 3 failed seals from new pumps seems very strange.I just don’t get how I would have that much bad luck with water pumps. Could not bleeding it 100% cause that?
