Flathead-6 Valve Adjustment
Hey guys, can anyone supply me a step-by-step procedure for adjusting the valves on a Chris Craft 95-HP "K"motor? I've got a valve that sticks open when the operating temp rises above 140F (momentary peak when powering-down to idle), causing the engine to idle very radically (usually dies). Help!....
Re: Flathead-6 Valve Adjustment
I don't know the procedure, but am concerned that adjustment will not fix a sticking valve. Is it possible that there is a bigger problem?
I think I would add some marvel oil to my fuel and maybe even my crank case oil, along with doing the valve adjustment.
Are you using oil with ZDDP?
I am curious to see what others suggest.

Re: Flathead-6 Valve Adjustment
I have to agree w/ Troy. This could indicate a problem. Has this motor been sitting for a while?. These K's are notorious for the valves sticking after storage. The MM oil may help loosen things up.
Boats are to be made of wood, otherwise, God would have grown fiberglass trees.

How do you know it's a stuck valve?
