oil pump

[ah1988ford]

hey as u guys know im rebuilding the 6.9l. I have to pump that was in the motor I never saw to motor run I bought it full of water. so the oil pump looks good but I don't know if it is functional plus I ruined the gasket for the pickup tube should I just get a new one? if so suggestions on brand

I don't believe these pumps go bad, but full of water? Eh I would but that's just cause i over worry some things. When u spin it does it sound terrible like sand/rust in it? When I rebuilt my 6.9 I went with Federal Mogul cause I didn't like how sloppy the mahl rebuit one felt. Probably nothing wrong with it but I'm picky even though the Federal Mogul costed twice as much.

I think you can check the clearances. I want to say Russell knows more.

As far as the oil system goes, isn't there a way to adjust the amount of bypass at the filter head somehow? A spring or something? Or am I confusing forums?

the water was lower than the pump it was not rusty, what happed was there was oil in the motor still so when the water got in it made the oil float up and it submerged the crank and oil pump. when I cracked it by hand oil was coming out, im just being overly cautious because I don't want to pull my motor back out, "do it right do it once"

"do it right do it once"

I had same thought process wen doing mine as to why I replaced it.

Take it off, submerge it in a can of oil and spin it by hand a bunch. As long as it's nice and smooth at that point, use it. I'm sure it's better than the aftermarket junk you would replace it with. Low oil pressure in these is a sticky bypass valve in the oil cooler.

Ain't that the truth. I went with my old stock oil pump when I rebuilt my engine cuz I thought the aftermarket ones probably weren't as good, but then again, i had 3 spare pumps to choose from.

There is a bypass, and it does have a spring. By why would you adjust it?
I suppose you could make it tighter for less bypass. By it shouldn't really bypass that much in the first place.

Just something I read on here and was curious.

 

[79jasper]

I don't recall.
I may remember slight talk about trying to raise the oil pressure.

That was probably it. Just got a **** eating idea to clense the oil better. Possibly will be parasitic to pressure but I can get off topic real easy so maby best to hold off till another thread arizes

Take the cover off the pump, if its not scarred up reuse it. All the new aftermarket ones have terrible clearances.
blue loctite the cover bolts upon reassembly.

And if your pump is bad get another stock one don’t buy aftermarket.

I wasn't aware they had aftermarket oil pumps for this engine.
