ok, ticket was bought.


So here is my problem with this-

This noise was here BEFORE the cam was replaced, and is there after-

Cam was broke in correctly, so, unless they sold me a flat (number one exhaust lobe ONLY mind you) that is just not adding up in my head.

Not entirely sure where the junk in the lifter came from since the lifter was new, that would be another mystery to me.

When this started, to get the noise to go completely away all we had to do was place a 5/8 socket ON the adjuster nut and it would vanish. Not a butt-hair of adjustment, just placing the socket on the nut would eliminate all the knockknock.

The noise is still there but almost gone once it warms up - not sure what the next move is but I am open to suggestion...

as the engine picks up in rpm, driving down the road - knock is gone

Not knocking the advice, but i can't understand how that can be the issue when the noise was there with a brand new cam-
