After revving my '54 235 higher than intended, it now has a knock. The noise sounds like something hitting thin metal , like the oil pan. It still runs on all 6 cylinders and still has good oil pressure. I have no dust cover over the flywheel/clutch, so the oil pan , side cover, timing cover and valve cover are the thin metal parts on the engine. I will remove it for teardown and repair this week.Thanks.
