I have a 67 mgb with a recently rebuilt engine. I belive I may have
a oil pressure problem and thought I would throw a few questions out
to anyone who may have some experienced similar problems.

1. What should I expect for oil-pressure out of a fresh motor. I am
   seeing 10-15 psi at idle and 50-60 psi at 2000rpm. I am using
   straight 30wt. When the motor is warmed up and the engine is at
   idle the pressure drops to 10psi.

2. There also is about a 30-45 second delay before i see any movement
   on the oil gauge when the engine is first started. This seemed a
   little slow to me.

3. I also noticed that when i am running the engine at 2000+ rpm
   the gauge reading isn`t steady. The gauge reading bounces between
   50-60psi. It seems to bounce with a fairly consistant cycle.
 
4. Do these symtoms sound like a bad oil-pump? I have already
   replaced the pressure-relief valve just in case it was the 
   problem.

Any help would be appreciated. I have called several shops and
haven`t got the same answer from any of them.

Thanks
