Well Hans, I'm not sure why wiser men than I haven't chimed in yet, but since they haven't, I'll throw two cents. I can't imagine how you have a main bearing issue with 37 psi. Certainly not bad enough to hear. Perhaps the offending cylinder is "dead", and that's why pulling the plug wire didn't change the sound? Or perhaps the knock is coming from the valve train or a water pump bearing?
