OK, my brother finally pulled the head on his B and found that he has one dry cylinder (#1). No slop in the pistons, all lifters are straight, rockers seem to be in check, valves need to be lapped but look ok for probably never being removed and no debris in the oil or on top of the pistons. The #1 was full of carbon and now realized that he has burned a lot of oil due to stick showing low. All the other cylinders look good. Need some direction please on how much further to go or what to look for that we havent done yet. BTW this is the same truck that was flipped into the river a while back.
 
How about the rings? If it got water ,even a little bit it can smash the rings.
It could be why its burning oil. A crack oil or compression ring causing blowby on #1 cyl.
Did you do a comp test before the head came off?
 
He went to every parts store and just about every mechanic close by and found lots of compression gauges, but none had the glow attachment. So in other words, no compression check. Rings makes sense to me except all the other holes have diesel residue and an oily carbon deposit. #1 has nothing but dry carbon. If there was a lot of blowby, why would this cylinder look like this? I am assuming that it is getting fuel along with oil, seems like it would be extra oily to me. Unless there is a constant fire in the hole due to the oil ie: burning on both strokes.

Ive hear the carbon build up glows like burning coal.Im guessing it would stay hot in that cyl after shut down drying any liquid fuel
Or maybe the injector is bad??
