I cant figure out what cause both intake and exhaust pushrods to bed on the same cylinder. They are really bend and one intermediate rocker was laying on top if the head under the valve cover and the other intermediate rocker was jammed between the valve spring and injector housing / hold down stud. Does anyone know what would cause this? I didnt do a compression test yet but the valves seem to hold when blowing air into the cylinder, the machine runs on three cylinders

If there was liquid in the cylinder, when the piston came up the valves could not open.
It is possible that the connecting rod is damaged as well.
Did you roll the tractor on its side?
Did you pressure wash it and get water down the exhaust.
Head gasket blown allowing coolant into the cylinder.

Ran fine one day and next day had dead miss.. I was hoping it was an injector but saw this when I removed valve cover.. no pressure washing or rollover...I need some kind of adapter to do compression test..mine won't work..it does not have glow plugs ..has grid heater in intake... Thanks
