O.K I have only a few hours of run time on my rebuild. When i start it oil psi is 60 -70 , then after warm up it drops to 10-15 psi. I've changed the sending unit and the oil , no change. So after a lot of searches I beleive it is my o-ring in the frount cover. Has anyone here had to fix this and is it possible to do without removeing the motor ? Also at what point of running low oil psi is it very bad on my motor , thanks.

 

You can pull the front cover with the engine in the car, it's just a pain in the ***. However, normally a failed o-ring would result in generally low oil pressure all the way around. Have you verified this with a mechanical gauge?

 

I'd double check with a mechanical gauge before bothering to do much else. You said you've changed the sending unit, but there could be some issues in the gauge or wiring.

I will be checking it in the morning with a mechanical gauge. I also have a Atkins bypass pellet and a shimmed oil regulater.
So what is such a pain in the *** about pulling the cover while in the car, is it one of those knuckle buster good times job ?

 

What is this "shimmed oil regulator" you're talking about???

The PITA with the front cover still on the car seems to be the front bolt for most people (and the verification of the thrust bearings' position).

The shimmed oil regulater is some thing that Atkins showed me. They flatten the oil regulater and put 2 little washers in between the oil pressure control valve plunger and the spring. They say it will take your oil psi up to 110 when tached

 

Hmmm...When you shimmed the regulator, did you drill out the pin? And if so, what did you repalce it with? If you used a split pin and didn't weld up the hole, oil pressure will bleed out through the pin.
