Farmall H cylinder head

Posted by SCK on August 31, 2005 at 16:52:27 from (208.20.44.78):

My Dad has a '40 Farmall H. I restored it 2 yrs ago. In Sept '04 it started to run rough and we found the no.1 exhaust valve stuck open. I took the head to alocal repair shop whose owner is an avid farmall guru and had it repaired. He told me that the valves had gotten rusty. I checked the head gasket over and couldn't find any signs of leaking. So I took the engine down the rest of the way and had the block checked for cracks and leaks just as I had done the year before when I originally restored it. Last week I went over to my Dad's and he told me it was running rough again. He also told me that he changed the plugs and wires and it didn't help. Out of curiousity I pulled the valve cover and found the no.1 exhaust valve stuck open again. I'm going to pull the head again but am lost on why we are having this problem. I could understand it if the tractor sat for long periods of time not running, but this tractor gets run frequently.
Any ideas or comments would be greatly appreciated.
Thank you.
