Oil Pump Question?

[MADDOG11]

I was just wondering if anyone has any idea of how many/if any oil pumps have failed/what is the chance of failure in our vehicles?

none that I've heard of...but you would never know that it failed. If it fails, you spin a bearing...then the pump eats the bearing schrapnel and hides it's own failure.

If you spin a bearing the pump will suffer badly.

If and only if you are reving it so high that the oil filter goes into bypass. Otherwise, the filter will catch all debris. I have one brand new Ford 3.0 oil pump left if anyone needs a new one.

dibs on the oil pump. PM price and contact info.

Thanks Tom !!!

Wouldn't that be the likely case? And I'm also guessing that the copper becomes granular, clogs the filter and it bypasses.

Sorry, someone else asked first. I'll get back with you after I hear from him.

I kind of doubt it. You'd have to spin 2 or 3 bearings to get enough material to clog a filter. But strange things happen. The bypass is not like a lightswitch either open or closed. It's a blow-off like valve that gradually open and closes. Probably starts to bypass some oil at 3500 rpms and is bypassing 60 % of the oil flow at 7000.

Damn! I've been looking for a NEW 3.0 oil pump. I got Pay Pal...

My oil pump was fine after spinning a bearing. There was some material on the gears, however, it comes off with a finger nail. Gary M. and I measured the clearances and it is still a good pump.

Understood. It makes good sence.
Thank you.

Then why did you replace it?

J/K...givin you a hard time...new is always better than "good used"
