I don't think it is. I've done/checked all the valve lash twice so far this year (while I was in there type stuff.)
I checked the intake valve yesterday, and it had that typical movement at TDC, and was opening/closing as it should.
However........I started thinking about the exhaust valve this morning. Is it possible that maybe the rocker shaft has backed out just enough to allow the rocker to fall into a pocket not hitting anything? And the rocker shaft is now sitting in just the right position to not allow any oil leak? So now, the exhaust valve is not opening. During the exhaust stoke, the burnt charge is just being re-compressed. During the intake stroke, there is a recycling thing that is going on. A mixture/struggle of combustion product trying to leave while fresh air is trying to make its way into the cylinder. And would the result be a cold exhaust header?
Is this possible?
