1997 GMC K3500 dually 4L80 4x4
We've been battling overheating issues and found combustion gasses in the cooling system. I also found the left side of the block cracked almost in half so how this old girl ran so good is amazing really. We've only had the truck a few months. Bought her in rough shape. I'll probably bake a list of all the work done so far at some point. We don't have the budget for a new motor right now, but the plan is an optimizer in the next five years or so. We found a used motor out of a wrecked truck that we're gonna put in next week. Got my boys to give me a hand pulling the old iron out yesterday. Got them off the video games.
