Re: Knocking Sound Comes, Then Goes
Many thanks to everyone for their inputs on this. WHN, I did exactly what you suggested about two weeks ago, new 20-50 and STP, but it's had no effect, so didn't get lucky on that one. Dropped the pan this afternoon, and no traces of metal debris in the oil, and nothing visually apparent, as well. Will address the center main possibility tomorrow and see what I find. Are we talking about removing the center main cap and peeling a thickness of shim away, then re-torquing the cap to 70-80 ft lbs? Thanks again!
