Well I heard clapping the other day so I knew one of my rockers came out of adjustment, not just the regular light ticking of TFS rockers, but I knew something was wrong. Took it all apart and saw the rocker had come loose, no big deal right, well I readjusted everything and then just last night same thing happened only louder this time, I take everything apart again and the SAME rocker came loose. Number 5 cylinder exhaust. I tightened it down and turned the motor over via the starter and everything looks fine. Im not sure if oil is supposed to be coming out of where the spring is though, is that normal? Anyone know what would be causing the rocker to come loose twice in a row? Thanks everyone!

Are the rocker tips coming off the valve heads? If so it could be an incorrect length pushrod. Pull the pushrod in question and see if the push rod is bent. I would suspect pusrod before bent valve.

Seems wierd to bend a valve when nothing is wrong. bending valves in my experience happens when your timing chain falls of because you forgot to loc-tight the bolt that holds the gear on.
