My 200 I6 is hitting on 4 cyls, I have spark and all that. It sounds like an intake valve or two listening to the exhaust. Is it common on these things to throw rocker arms? If so, can I just pop them back in?
There has to be a reason that the rockers are coming off - if that is what happened. Check your firing order first and then your plugs. It is possible that your plugs are simply fouling out. I had this problem on my 250 six and went to the older (hotter) plugs and the problem went away.
Thanks for the help Paul, but I'm 100% positive its a rocker or a valve. If it's as simple as popping a rocker back in I'll do that, but I'm trashing the six as soon as I get around to it. I really just wanted to know if this is common on the 200 I6.
It is not a common issue as far as I am aware. Flat cam lobes would cause it but that isn't common with the sixes either. Since the rockers are on a shaft it is not a stud pulling out. It might be a couple of bent push rods but even that isn't common.
Burnt exhaust valves are not unusual on the sixes though.If it were an intake valve it would be popping through the carb...If it were burnt that is.
