Ok Guys, Sorry it has bee so long to respond, With all of the work that I have been doing on Droopy, I have neglected stuff at the shop. So this week I had to just leave the truck alone, and get some other stuff done. So with that,..and a Computer Crash this week I have not been able to update or do much with the truck.
On top of that we got 6" of snow today, the first plowable snow of the season for us.
Here's the update on Droopy, Had the head pressure checked and magniflux, no real problems some minor cracks but they are non issues. It passed the pressure check, Had it flattened, Put the head back on and still had the same symptoms. Back at square 1!
We did a hydrocarbon test and it failed miserably, there were consistent bubbles in the glass, like a fish tank bubblier.
Here is a short video:

It slowly turned yellow showing combustion gasses in the antifreeze.
At this point I just need to be able to plow snow, so with the thermostat removed, and cardboard in front of the radiator I figured it would be fine just putting around the car lot for the winter taking care of the plow duties.
Then I decided to throw in a bottle of "K Seal" K-Seal - Permanent Coolant Leak Repair I have used this before with pretty good results. I figured that it would not hurt anything and if it got me through the winter all the better.
I got to the shop this morning pulled Droopy out of the garage, and started plowing. It did GREAT! Love the torque and response of the lil 4 banger! It just chugged along like a tractor. The temp gauge raised off of 130 deg, and the factory gauge moved up as well. I got enough heat out of it to be comfortable in the truck and defrost the windows. After about 30 min of plowing I shut it off and headed to the Auto Auction for the day.
When I got back I finished up plowing with the same good results, I opened the hood, checked the radiator hose and there was NO PRESSURE in the coolant system,...NONE! It has not burped out, the levels were good and I was getting some heat as I was before.
So at this time it appears that the "K Seal" has worked in plugging up my mysterious combustion leak.
Understand that I know this is not a Permanent Fix, but if it gets me through the winter, I will be pleased, Then I can pull the motor and rebuild it this summer.
So I will drive it a little more, do another hydrocarbon test, install a thermostat and see what happens after that.
Thats it for now,..!
