Are the lifters rattling? If not your getting oil to the top you just have a problem with your supply line. If they are rattling you may have forgotten to install (or they blew out) the lifter oil galley end plugs. They are behind the cam gear and look like a little freeze plug. I like to tap these out and install pipe plugs in them.

When you checked the pressure did you check it at the turbo or did you connect to the fitting at the back of the block. I'm wanting to know if the gauge was deadheaded (straight line from block to gauge) or in a flowing system (oil going through turbo).

the turbo has oil but dont read anything and we get oil presure at the bottom of the motor but not at the turbo, and we checked with a manual gauge the engine has no rattles and it has lots of power but no oil pressure. we checked the valves in the cooler also and there not stuck nether so please help we use the truck to pull our dragster to the track and race season starts this weekend.

Try disconnecting the supply line at the block and connect the gauge there, you can clamp vice grips on the turbine nut to hold the turbo from spinning. See if you have any pressure that way.

Just an update on this problem. After a few phonecalls and pulling the engine they found the lifter oil galley plugs in the front of the block were missing.:damnit
