I have a 1992 saturn sl1, and[u:a6957298b0] i have replaced the oil pump [/u:a6957298b0]and checked the oil pressure relieve valve =(I used a pry bar to pop it out),and the valve is good!. I checked the 'o'-rings and they look good. and I put it all back together and it still ticks!.
I took it to a saturn dealer! and they said it was not getting a oil pressure reading!?. and that they would charge me $550.00 to check it out more. by dropping the oil pan and removeing the front cover!!.
after what i told them what i replaced and checked??. So is it likely a pluged oil passage? or would it be a 'o'-ring problem!?. or would it be the
crank shaft seal!?. I also took it out!, used a srcew=driver to remove it, it looked a little worn!?.[/b]

It sounds like the check valve in the oil pump isn't working correctly and is by=passing all the oil it picks up. Me thinks it may need an oil pump. Good luck

The book says to replace the relief valve if it has been removed.

"Whenever the valve is removed, it must be replaced because the puller jaws will damage the valve sealing seat."

Good luck and let us know. :)

Suggested Repair

Replace the oil-pressure relief valve, because it was removed and the sealing seat can be damaged by that removal. If pressure is still absent, replace the oil pump so a faulty check valve is not bypassing oil.

Conversation Summary

The owner of a 1992 Saturn SL1 reports engine ticking and no oil-pressure reading after replacing the oil pump and inspecting the relief valve, O-rings, and crankshaft seal. A dealer confirmed no pressure and quoted further disassembly. Experts say the relief valve must be replaced after removal because the sealing seat can be damaged, and a faulty oil-pump check valve may be bypassing oil, so a new pump may be needed.
