    Hey guy my brother has a 6bt out of a 1997 3500 12 valve. We got to looking at it and #6 exhaust valve is not working. Any ideas? bad tappet lifter or cams gone!?!? Need to get this on the road soon!!

    Injectors are good, and have been pressure checked. Valves adjusted Compression test good, all 4 around 400 I still have a miss. Low power, poor fuel economy. If I keep the idle around 760 when i put it in gear it LOPES. What else to check?
