So a week or so back I was able to get my truck out of the garage, fired up, coolant system bled, and took it around the block a couple of times. After a couple laps around the block it started to run warm, about 235° F. It would never get any hotter but I figured something had to be wrong. At idle it would never overheat and the fan would kick on/off and keep it around 190° F. I did a block test on it and sure enough, combustion gas in the coolant. Wanting to be able to put it back together over the Thanksgiving holiday, I took part of today off, got the heads pulled, and was able to make to Noland’s cylinder head shop in KC before closing. They’ll manga flux them, check them out, and surface them. Hopefully I will be able to pick them up next Wednesday.
