Where do I start looking? I have lost 20 psi of oil pressue in about 20 miles and I now have lots of valve train noise, Roller cam. I have about 2000 miles on the rebuild. Oil pressurer has dropped from 30 psi hot to 10 psi @ 900 rpm. The noise is across the rpm range no lost in power.

Thanks

Pull the VC's to make sure your getting oil to both sides then check for excessive lash or if your rockers are being galled.
This happen to me once. 20 miles on fresh rebuild then suddenly oil pressure loss of 15 lbs from 45-30lbs hot and valvetrain noise(drivers side). I finally pulled the timing cover after replacing all the lifters and found a galley plug had popped out. HTH
