All of the white scale will flake off and settle out like sand. Its hard mineral and abrasive. Poorly maintained cooling system. When backyard joe mechanic dumped in the coolant from the first engine swap im sure the whole bucket went in. Even the crunchies in the bottom... This whole thing could have been avoided IF somebody would have put together in their head the following. If garbage comes out of the cooling system when you drain it there is more inside. Look in the top before you dump coolant in. What do the cores and inside look like? Mechanics 101...How could the reman block have 2" of sand in the liner bores? Would that not have been taken care of when the block was remanufactured in Denver? Did someone put sand in the coolant system filling up those cavities at the same time wearing the crap out of the impeller?
I'm a bit confused by this sand...

So apparently the last people to work on the engine(dealer mechanics) did not do a proper bit of trouble shooting or they would have found 90% of the problems. Lacking doing that if they had just done a fair job on test running it after they had assembled it the problems would have reared their head before they gave it back to the owner.Birken, It does explain it very well. The head having no coolant was nuclear hot, which explains the valves that were warped. But the block having coolant in it was much cooler, which is why the pistons did not look that bad.

Just to add to that thought. The district manager said that they probably could have caught the over heat problem during the stall check and running it outside, IF they would have used a cylinder heat shot gun.He admitted that they didn't do that .So apparently the last people to work on the engine(dealer mechanics) did not do a proper bit of trouble shooting or they would have found 90% of the problems.

Just hoping this time they do a proper repair and give it a good long test run to be sure it is ready to start moving dirt!
I'm so happy for Steve! Hopefully the rad won't be over $2000. Even though it's a little more to spend he should have a good running machine in the end.
