[Farmall] Super A engine trouble...

[E. John Puckett]

Did he run compression check on all cylinders?  From what you have 
posted, I would suspect bad or stuck rings on the one cylinder.  A valve 
would cause the low compression, but not the oil fouling, unless the 
guide was badly worn.  At this time he is right, a tear down and 
inspection is needed.  If compression on all cylinders is good, you do 
not have to do a full overhaul, but if the engine is generally worn and 
you use it quite a bit, that is probably the best way to go.

I have a worst-case scenario of a $2500 rebuild or a valve, or a head gasket problem (the engine does seep a little oil from the head gasket area).
