Well, the 350 in the pig is running great, but I have noticed over the past few weeks that the oil pressure has been getting lower and lower, until now it sits at 0 at idle. It previously sat around 25 PSI at idle. It still comes up when driving, and it also has great pressure when it is cold. Otherwise truck runs great and has good compression.
One last thing, if I let it idle for a while, a distinct tick can be heard from the top end. I was thinking it might be a lifter rattling because of lack of oil pressure, but since I am chevy stupid I don't know. It never made a noise before the pressure started dropping.
I am suspecting the Oil pump, and have ordered a new High pressure pump(I hope I don't start blowing seals)
Does anyone else have any other ideas of things that would cause this?
thanks,
Dan
