Flushing a engine block that has been sitting.

[earntaz]

I hate to tell you this -- but with that much time sitting, your only alternative may be tearing the engine down and "hot-tanking" the block/heads. Even dumping cooling system cleaner in the engine may not work. The water jackets in the lower portion of the block are probably filled with solid material. Some cleaners will flat attack anything that is aluminum or white cast material and will be easily destroyed -- including the radiator and heater core. Just my .02 cents worth -- but maybe someone out there has a better idea.

Good LUCK
