Default Re: New guy with questions.

While you have the knock going strong. Short out one spark plug at a time, you may find one cylinder that when shorted the knock stops, if so mostlikely a rod knock. It's not real hard to pull the pan and check all the rods and mains are a bit harder to do, however it's doable. While you have it knocking press in the clutch, if it stops you may have a bad main thrust bearing problem. The knock getting better when you retard the spark indicates a rod bearing or a main bearing. If you plan on doing the checks , let us know what you find. Good luck, PS there's lots of real good guys on this site, a few skirts also.
