Title: Update on my oil pressure problem
Post by: Alan on April 12, 2009, 07:51:22 AM
My new pump won't be delivered until tomorrow so being restless and wanting to know what was causing my low pressure,  I took my old pump apart and checked it out for wear. It looked ok so I pulled the new pump and put the old one back in, changed the oil and filter and started it up. The pressure was 40 lbs at cold idle, so I drove around for a while to warm it up. I ended up with 20 lbs at idle and 35 lbs when I'm driving and thats with a 42 year old pump. That verifies that the problem was the pump. The rebuilder said to send him the bill for the new pump and he'll reimburse me for it.  The new HV pump should give me even better pressure.
 
I have to say, I'm glad I don't have a GM car. Changing the oil pump would mean dropping the pan.  Changing a Mopar is a breeze.(http://www.moparfins.com/forum/smileys/smiley4.gif)

I can't believe he didn't put a new pump on a new engine.  Anywhere else that's SOP

It came with a new pump but it turned out to be defective. I put the old one back on to see if I still had low pressure. The pressure was good so I knew that that the new pump was bad.
