I had it happen on the highway also, that one took out the crank. RTV in the relief valve, no it wasn't mine.
Ok so I will ask you too. When I primed the pump after buttoning everything back up and got a 58 lb. reading on the guage, you're saying that I can't trust that reading and it could still be the pump? I don't understand, Craig.I had it happen on the highway also, that one took out the crank. RTV in the relief valve, no it wasn't mine.
Yep, checked the gear on the distributor as well as the intermediate shaft. 20 lbs. when it's hot is perfectly acceptable, but not when it's dead cold. I really appreciate all of your input, just looking for something that I've overlooked. Still haven't checked the valve train. I keep thinking it's an obstruction and maybe it will pass...like a kidney stone right? HAHA! Thanks, Craig.Maybe the relief valve wasn`t stuck at that moment when you primed it. Dunno. It may not be the pump, just as suggestion because I `m just trying to think what else it could be. If it was running bad and the oil pressure really dropped off then I would suggest maybe a lifter popped out but you say it`s runs fine. Btw, 20lbs at idle is not bad if it goes up to 40lbs or so like you said.
Yes it is the pinned gear. Running pressure before the problem with a cold engine was around 62 lbs. CraigIf it is a Mopar performance oil pump drive gear it should be pinned. A stock one can spin as it is only pressed on. Also, when I primed my 340 it read like 70lbs with a drill. Actual running pressures were much lower.
Don't know the actual weight oil that I drained out (it's the oil that was in it when I purchased the car) It's heavier than what I put back in. Replaced it with 10w30 Mobile 1 synthetic. Not going to race the car with this oil, thought that the obstruction may pass easier with the lighter weight oil. I'm at the point of trying anything even though it may sound goofy. CraigBTW, what oil are you using?
