Re: [AMC-list] Oil Pressure II

Jim,
 Sounds like the only problem you have is your oil pump end clearance was set to 
the loose side. You really dont have an issue unless your running the engine 
hard and up past 5000 RPMs. DO you have a blueprint from your engine build? What 
were the pump clearances? If it really bothers you you can swap in a thinner oil 
pump gasket Bultear sells a .007" gasket. Stock gasket is usually .009 to .012

Subject: [AMC-list] Oil Pressure II


Thanks to everyone for the input.  Here is a little more information.  When I 
initially start the car I get 40lb of oil pressure.  As the oil get warm the 
pressure falls.  After 10 minutes at idle of 700 rpm the pressure is at 9-10 
lbs.  I have a mechanical gauge with copper line.  If the pressure relief valve 
was br stuck, wouldn't the pressure remain the same?  


I have about 80 miles on the rebuild.  I removed and cut the oil filter (with 
the appropriate tool so no shavings would be in the filter from the cutting).  I 
checked the inside of the filter and could see NO metal shavings.
Anyway, if it still sounds like it could be the pressure relief, how do I check 
to see if it is bad?  I hope that is the problem because if it is bearing 
clearance I've got a big problem.  Any ideas?  Past experience?  Any information 
is appreciated.


Thanks,
Jim
