Mr. SCOTT. I have an 2002 Saturn. I did an engine swap. It ran dandy for a day. I heard and awful knock. I assumed a rod. I am changing to a new engine and found a loose flywheel behind the pressure plate. Is this a possible culprit for the knock? Thanks. I know you do not charge, but do you have a preferred charity that we could throw a couple bucks to?

Yes, that would make knocking. Give money to the spca
