I completed one cylinder replacing the valve seals and decided to put the valve cover back on after torqueing down the rocker arms on my 4.2L engine. I wanted to see if I could tell a difference in this cylinder spark plug wise after the change.
Anyway, I'm now hearing a clacking noise when the engine is running. I remembered what someone said about replacing the right components back in the right place so I took the valve cover back off and changed the rocker arms around. This seemed to make the sound better but it's still not sounding good.
Any ideas on this?
Thank you,
Bill
