I picked up the car in my sig last night. Noticed that when the engine gets to temp and its hot out in traffic, the oil pressure is between 20 and 25 psi on factory gage. It goes up to around 40psi at 3500.

My previous 98 with stock internals was 40 psi at idle ant 65 under throttle. Since the engine has been opened up, should I be concerned or is this sufficient oil pressure? I emailed the P/O, I don't know if he kept the stock oil pump or upgraded when he cammed it.

Yeah thats a little low. Might wana check the o-ring on the oil pump. That seems to be most everyones problems.

I got ahold of the previous owner, said it has stock oil pump and LS1 timing chain. I went ahead and ordered the ls6 pump and ls2 chain. No point going through all that work to just do an inspection on an outdated part anyway.

My stock 99 gets the same as your old 98 did and it has 99k miles. Don't get on your car until the new oil pump is in.
