What do I do about low Oil pressure? It was down to 15psi so I added 2 quarts and it went up to 30psi for like 20 minutes and it was back down to 15PSI. Wednesday night I had 60PSI and after filling up at 76 I notice that the PSI as down to 30 and then when I got home 15PSI. How can I fix this?

either you've got a bad gauge, bad sending unit or bad oil pump.

yes you need to find out what is causing the low oil psi is is a gage sending unit or is it the pump or bearings?

It kinda sounds like when the oil warms up you loose pressure. Either change your oil or yur eng is gettin a lil loose. Mine does the same thing so I run 50 weight and have like 70psi then after warm up it drops to 30 and when hot it damn near goes away.

Well changed the oil and it was fine when it warms up and is idle it goes down to 15 but when i start giving it gas the pressure goes up to 30+ depending. Seems fine now drove it around for awhile. I think I have a loose alternator wire cause sometimes she doesnt have enough power to turn over the engine and I have to jump it or do a compression start. The oil that was in there was really black and kindof sludgy. So I put in 7 quarts of Castrol GTX 10w-40 in there.

When Crunch Built this Motor He built it to idel at 2K so you dont like the oil pressure rpm it up... I had it ideling at 1400 .... Besides mat you only need about 7-8lbs at idel as long as when you gun it it goes up your good to go... This Truck has HI VOLUME LOW PRESSURE MELLING PUMP... NOT HI PRESSURE HI VOLUME..... Its oil pressure has done it since the day it was made....It kida freaked me out too until crunch set me strait on it.....
