cam installed (problems)
my question the oil pressure gauge wont go past 40 and when i let off the gas it goes back down to zero.
a) your oil pressure sensor is bad
b) one (or more) of your bearing is screwed, therefore causing loss of pressure
c) something is blocking the flow of the oil near the pump possibly
Make sure none of those are true.
Could be the oil pump O-ring....if it gets pinched in there you lose pressure like a ****...
For your sake I hope it not because thats a lot of work for a stupid cheap O-ring

As far as I know, it should be making some racket under the hood if it is the o-ring, so if its nice and quiet then you should be able to exclude that scenario, though...
ttt...
If its quiet then it could be the sensor, but if you didnt have that problem before with the guage, then I dont see why it would be the sensor....but stranger things have happened...
But if the sensor is cheap, heck why not try it?
