Hi Doublem1,
Without seeing and hearing this compressor,my first guess is that you have a bad connecting rod. The compressor on this unit needs to sit on a level surface.If it sits at an angle and just happens to be a little low on oil it will starve one of the two connecting rods of oil.You will need to take the head and cylinder of and look for the problem. Do not run the compressor as a bad connecting rod could come loose and be driven through the wall of the pump.Hope this helps.good luck.
