I think my OPSU is going bad. My oil pressure was always above 40 psi at idle after the heads/cam swap. I was driving around today and my pressure gauge started to fluctuate from 25 psi to 40 psi. It would increase with RPM but it would flutter erratically. I checked my oil level and it looks fine. I have approx 1500 miles on the clock after the swap and I'm using a ported LS6 pump.

Bad OPSU?
Oil Pump going bad?
Clogged Filter?

Any ideas?

I think I will start with the OPSU and a oil change.

Where is the OPSU located? Are there any pictures floating around here?

I tried the Search feature with no luck

Thanks

They sell a "special wrench" at PEP boys for removing this sensor.

yeah but be very careful when removing the manifold or you will take the sensor out like me. It doesnt take but a little touch and you will be a your local dealer purchasing another for about $70. it is on the drivers sind behind the manifold almost were your coolent line connects.

the socket isnt nessesary, but you will be better off getting it. the sending unit is a hex, but the edges are rounded, and you will just save some time and headache getting the proper socket
