Default Re: Newbie knocking paranoia/ignorance

Welcome to the club! Here are two things you can try:

Exhaust leak-spray some wd-40 around the manifold and if the engine sound changes there you go. Easy peezy to change the gasket.

knock-short out each plug if you can hear the knock sound at an idle. If the sound goes away then you have a bad rod bearing.
