When the engine was in the machine shop, I had it tanked and then pressure cleaned. If there is something going on in the block, it might be that I built the engine in 1993. It was then stored with the other parts. I spent the next 18 years in the military. Continued working on the truck but never got all the parts in one place until this spring. I have had problems with other parts that I reworked, the radiator was taken to a shop to be reworked, when I installed it, it leaked, I took it back to the shop some 10 years later and they fixed it at no charge. Then I installed the fuel tank that was repaired at the same shop, the fuel turned red from the slosh seal they put into the tank. Then like the like radiator it leaked also, again they repaired my spare tank at no charge.
You see I think problems find me.
