How to assess condition of oil pump

[Ho Hum 74]

Hi guys,

I'm re-building my 1974 2.7 and thought I might have had low oil pressure. I'm not sure if it was the pump or leaking bearing or if the guage was incorrect. I removed the pump and it is the 'upgraded' 1976 type. Who can I send the pump to who can calibrate it and tell me if it is good or not?

Thanks

hmm.. I'd expect EBS could but nothing jumps out at me as to where you could send it.

I sent mine to Steve Weiner when I rebuilt an SC engine that had an ostensible 90,000 miles on it. He took a look at it, said it was just fine, and he was absolutely right. With the rebuilt engine warm, I get like four bars of oil pressure at 3,000 rpm.

Thanks guys,

How do I get hold of Steve Weiner?

Can't Saul @ PP do that for you locally?

Edit: You might want to post in the Rebuild Forum. It maybe something you can assess yourself with the correct information that those guys can direct you to. I could swear I read some clearance measurements for the pumps somewhere.

Probably but I don't use Sol. It's just something about his bedside manner that irks me.

It's fine. I can tell from here.

Seriously, even experienced wrenches can often count the oil pump failures they've heard about on one hand. I certainly can. (I'm not a professional mechanic) I believe JW commonly inspects and reuses oil pumps. Depends on mileage, but a pump with a quarter million miles already on it, very possibly may still be good enough to reinstall, at rebuild time.

Well my oil pressure was lowish. I agree, when I look inside it, the blades look good, no significant scoring or cavitation etc.
