wheeling the 2004 dodge today and i start to hear a tapping noise, oil pressure never dropped below 40 psi oil not discolored or smelling of anything. exhaust has a loping noise sound like top end we removed the valve cover found all rockers had proper play except number 6 exhaust had sizable play , turned engine over with cover off push rod and rocker move the same on all cyclinders just # 6 exhaust has alot of play between the rocker and the valve spring bridge, pushrod seems to be straight lifter seems to be ok no metal in the oil, valve springs seem to be stuck down just a little valves are not touching the piston, any ideas

 

anyone have a idea what to do

 

funny any real help

 

Sounds like you dropped a valve. Pull off all of the rockers and check the valves out.

 

rockers ok springs ok # 6 cyc under tension just a little on exhaust side

could i have dropped a valve seat

 

Do you have stock valve springs still?

It could be a valve seat. Are all valves on #6 sitting at the same height without the rockers on?

 

hard to tell they look close
stock spings 106k miles

# 6 inner exhaust lower than the rest pulling the head now, hoping the pistons are ok if not haisley is getting a call or maybe it 12valve time
