Well did more checking and the last time I ran it the lifters werent clattering but the pressure was at zeron on the mechanical gauge and the line to the gauge was starting to become clear. So I figure it had just enough to keep the lifters from clattering but that was it.

Ran about 30 on fast idle cold and as it warmed up it dropped off quickly. The most I could get it up to was around 40-45 at about half throttle or maybe a little more warmed up. let the pedal go and it dropped down to zero once again.

I think I've got bigger issues as its smoking pretty good now even out the smog pump tube thats broken off, ruling out condensation. That and the frame is broke ahead of the steering box.
