What you need to do is take it apart down to the bare block and take it to a machine shop and have them hot tank it.

Do what I do, load her up with a pocket full of quarters and go to the car wash and get the wand out and go to town.

Should have said, load her up, take a pocket full of quarters, and go to town and wash the water jacket out.

I dont know how large the water jacket is on your engine, but when I went to clean out my Detroit Diesel 6V53T, I was armed with a screwdriver, a spray bottle (clorox bottle) full of diesel, and a 3000psi power washer. It is amazing how much scale and rust buildup comes flying out of the drain holes. The cylinder liners are removable on my engine, so I could get in there with a flat head screwdriver and really get to town on the rust. If you cannot borrow a power washer from a neighbor, or rent one, I would find out first what your engine block is made of aluminum or iron, and then look at different radiator cleaners and scale removal chemicals. Alternatively, hot tanking the engine works well, but can be hard to find a place around that has one.

Good luck,
Chris

If you do the hot tank method, expect to replace cam bearings. I usally go to the car wash with long screw driver and some stiff wire. I have seen some engines so packed with lime, I had to use a long drill to get that stuff out.
