[AT] Track loader update

[Spencer Yost]

In addition to these messages, I had a phone call and private messages 
indicating stop leak might be a good thing to try.  But before I do 
that, I did want to post a few tidbits:

1 - Water came out of the neck sort of slowly and I got more foam than 
bubbles.   It was nothing violent.

2 - Don't think hot spots or anything are to blame, as the foam/bubbles 
appeared just as soon as I ran on diesel

3 - Tonight, after 24 hours of cooling, the coolant level is about 2 
inches from the neck.   This probably translates to a quart or so - 
about the same amount that came out of the radiator.   I don't think I 
am leaking much, if any, water back into the combustion chambers.  When 
I start if back up after these rains, I'll first take out the sparks 
plugs and see if any spray or mist comes out of the spark plugs holes, 
just to be sure.

4 - Oil is clear and the level of the oil is about the same. 

5 - The coolant would shrink back down into the radiator at full 
throttle, and would only bubble out at half throttle or less.   I 
thought that was interesting, as I had never seen that.  Usually It gets 
worse with more throttle.

6 - More smoke than I like from a stack, and whitish gray in color 
(water??).

7 - While not really "rough" running, it sounded a bit like it was 
missing (not bad like a gas engine with a bad spark plug, but a 
pulsating sound like one bad injector will make a diesel engine sound.  
This was unscientific and was based on sound only.  Does back up my 
compression test on gas where #1 cylinder was 45 psi while the others 
were 60 psi.

Just a few more facts to ponder.   Thanks again for everyone's input,

Spencer
