where is the oil pressure relief spring located?
Discussion
my oil light has come on and oil gauge shows zero pressure, the oil level is fine. Where is the oil pressure relief spring located on a 4.2 cerbera please? any pictures would be a big help. I want to replace it and see if this is the problem to gauge and light, thanks for any advice.
Hi,
From memory' I believe it is accessed underneath the car on the drivers side,
We replaced mine about 6 years ago, the retaining bolt was well stuck in place, so much so we were concerned about cracking the surrounding case, so I sprayed releasing fluid every couple of night for a week before we had a final go, thankfully it worked the spring was shot though....
Good luck,
Steve.G.

Are you the chap on Facebook with zero oil pressure?
If so I fear the relief Spring is not your issue, I would expect a reduced oil pressure from a broken spring or stuck piston in the relief valve not a total loss.
It sounds like the pump may not be turning which would initially point to a failure in the auxiliary shaft probably a failed woodruff key.

...and mine was the drive gear shearing off the nose of the pumps' driveshaft inside the timing cover. The three pumps share a common drive.
Was your PAS working last time it ran? Did it overheat? My first check would be a quick visual to see if the PAS pump is turning with the engine, turn the crank over 'by hand' if you don't want to start the engine. If it is turning, then that eliminates the drive side of things to all pumps. If it's not, it could be just the last part of the drive to the PAS pump, but it could also be driving none.

The rocking the engine and making sure the PAS pump turns would be my next thing to try so at least you know the pump is turning.Was your PAS working last time it ran? Did it overheat?
