Now, to continue... what's the next best thing to a leak in the fuel system in -33 C?
Well, of course, a WORSE leak. On the way home from Loon lake, the diesel injection pump itself started a very bad leak. By the time we reached our house, there was diesel all the way down the left hand side frame rail, under the truck, and up the back window.
Well, f**

k @#$$#$!!! Luckily, I am a very fortunate guy, and my friend John B from Radd Cruisers was able to show me how to remove the IP, overhaul it (seal wise) and put it back in. As well, one of my best friends Greg ("Ranger Dave" here on MUD) was able to come up to Kamloops for 3 days and help too.
So, in the relative warmth of my new wood stove heated shop,

we stoked the fire and overhauled the pump. At the same time, we removed the transfer case, and replaced the transmission output shaft seal, which had been leaking atf slowly ever since I bought the truck.

Removing the transfer case from the transmission...
Output shaft on the transmission (the seal around which was leaking into the open space between the two sealed units - trans and xfer)
The transfer case on the bench, with the CDL motor removed. This little bugger ended up being a great deal more work than originally expected, since water had gotten into the armature housing, and had rusted everything up - including the 3 little limit switch prongs that tell the motor when to start/stop. I ended up having to completely re-wire the CDL motor with new wiring.
Put everything back together, remounted the transfer case and cross member, CDL works great now - nice and strong and quick like it should be.
