[AT] Int. 184 overhaul - a mystery

[charlie hill]

Well it sounds like you are committed at this point.  Good luck with it. 
It'll be sweet when it's finished.

Thanks, Charlie. The problem was that the engine would start and run
reasonably well for about 15 minutes, then it would start to pump oil
fumes out the breather and get quite hot. After about half an hour, it
would just quit and would not re-start until it cooled down. Based on
past experience with Farmall Cubs, I assumed that the rings were worn,
causing the fumes, but I don't know what caused the engine to quit.
After I got all hood off, I found that the alternator/fan belt was
loose, so that *might* have been causing the poor cooling. (I had
converted to a Pertronix ignition module and brand new NAPA coil with
internal resistor, so I don't *think* the coil is bad.) As for oil
pressure, it has only an "idiot light" off the back of the oil filter
housing, and that would go out after a few seconds of running and not go
back on until the engine quit. So I was rather surprised to find the
spring in the sump. I have not yet determined if there is a spring in
the oil pressure control valve. The head had a little bit of carbon, and
the plugs looked fine (no fouling, no burning) when I removed them. The
bores are smooth but dark. I will find out more when I ream the top
ridge, pop the pistons out, look at the rings, and run the bore gauge
down the bores.
