Hello everyone I've been searching everywhere trying to find some answers about the knocking sound many get from under the valve covers. I had a piece of my timing chain guide missing and had a chain tensioner that got sheared. I've replaced the whole timing assembly so new chain, guides, tensioner, I even replaced all the lifters, rocker arms, passenger side cam phaser(this is the side the knocking is coming from), rod bearings and oil pump with pickup. I found the pieces from the timing assembly in my oil pan and had a lot of pieces in my pick up. Any ideas on why I still have the tapping noise? Im guessing clogged oil passages however I don't know how to go about clearing. Anybody ever have this problem?
