Do oil pumps go out on our cars?

Im still left wondering why a pressure test didnt uncover this issue....thinking maybe all the crap that the chemical flush knocked loose clogged up the weep hole

Well....................................They've been known to fail with high rpm use.

Couple of choices.

SPMS VQ HR / VHR OIL PUMP

I have thought about upgrading the oil pump, but if it ever breaks down im most likely gonna go with a dry sump setup for track duty so i dont have to worry about oil starvation so much

Impellers were fine on the pump, but coolant side seal has seen it’s better days....https://uploads.tapatalk-cdn.com/201...a1e3f2398f.jpghttps://uploads.tapatalk-cdn.com/201...77495f3f00.jpghttps://uploads.tapatalk-cdn.com/201...db60afadf9.jpghttps://uploads.tapatalk-cdn.com/201...0a9ade6580.jpg

I see nothing wrong with that water pump. It appears you have blown head gaskets. That is what I would change next.

So the fact it was leaking from the weep hole means nothing? Not even the orange sludge buildup and flattened out coolant seal?

The weap hole is on the back of the front cover. I haven't seen a picture of that. That is not the water pump weep hole on the front cover.

Same white chalky residue, plus water and sludge on the rear cover, i showed the front cover to show that the person who worked on it before me had sealed the weep hole

Forgot to mention....thanks for all the advice dread, really helped speed things along when putting this monster back together lol.....also thanks to spooler, phunk and anyone else I forget to mention for putting up with me these past few months. It has been quite the learning experience, but I’m all the better for it :)

Im just glad you found something and handled it. For I while there I was wondering if you weren't just an automotive hypochondriac or running out of things to "fix" around the house!! :rofl2:
