buick idle oil pressure

my buick even fire is a late 70s engine with unknown miles. once warm the idle oil pressure is about 10-12 psi. should i worry about it. or rebuild the pump? sometimes if i warm the engine up and re-start i get what sounds like a lifter noise. if i let sit and re-start it goes away.

 

Thats actually much more then the average gets. This thread has popped up more times then knuckle pudding.

 

Mine runs a solid 35lbs. hot. Of coarse less than 500 miles on the rebuild and the high volume oil pump.

 

At this rate it will take me 50 to 60 years to get close to that. R)

 

thanks for responce to question i searched for a half hour or so before post and still wasnt shure of normal psi at idle. I found oil pump rebuild info and may look at the pump if pressure goes lower. or i could drop the oil pan and look at crankshaft bearing clearences? any thoughts on those two ideas.

 

Seriously 10 is good when hot.
I read of jeep with 5 and nothing bad happens.
I put in a new pump and shimmed it and I get 25-30 cold and 9-12 hot.
Your not going to do better than that unless its brand new motor.

A high pressure pump has been know to cause new problems for the dist gear which is where the oilpump gets its power.

As said there is tons of info here on the whole mess.

If you have 10 your good.
I always throw in a can of STP on older motors. FWIW

 

10lb's oil pressure per 1000 rpm's is a safe mumber to go by.
