Valve Train Noise

[Randy Hagins]

I recently had my motor rebuilt (206/206 cam, new lifters, 92 lb springs, HP/HV timing cover/oil pump, 30 over pistons) and my oil pressure at idle is 10 PSI and about 20 PSI at 2000 rpm. After I get the car up to 18 pounds of boost(oil pressure does go up to 50 PSI) and let off I have what sounds like lifter noise or valve train noise on the passenger side (after car runs a few minutes of normal driving the noise does stop). I took the pass side valve cover off and let the car run, I saw oil pushing out of the push rods, could I possibly have a bad lifter or any other suggestions about what the noise may be??
Thanks!!

What was pre-load set at, any idea? If you have a stethoscope (or a piece of hose to your ear) can you isolate it to a specific area?
