Oil Pressure never comes up

[graf703]

I'm installing a used 2g engine to replace my blown repo one. At idle the oil pressure light blinks intermittently when I rev it up just slightly it stays on. It turns off as the revs drop back down. This is the first time we've started the engine since installing it. I know most people have problems with the idle thing but everyone elses goes away when they rev it. We swapped the pressure sender from the old engine and still have the same results.

My understanding of this is first the pressure relief valve should be checked. Second the oil pump and third the bearing clearance. Any other suggestions or tips or insights?

I was having "low oil pressure" woes and took the oil filter housing off of the motor and cleaned it out thoroughly and all is well.

I had a 90Tsi Fwd and oil pressure was always low, but it always ran great. When I posted about low pressure, some people said that there car does just what yours does: blinks when idling. Best thing to do is get an aftermarket gauge and plug it in place of the stock sensor and check the pressure. I forget what it is ? 60psi at idle?

25 psi at an 800 rpm idle. At least thats what I get and it climbs to over 100 psi depending on rpms.
