Pressure Cleaning Media Engines

Hastings Manufacturing Company has published bulletins in the past on glass beads and other pressure blasted cleaning media that is not completely removed before the engine is reassembled.

When engine parts such as heads, intake manifolds, blocks, etc., are pressure blasted with glass beads, steel shot, or various metallic oxides, this material is blasted through all the internal passages of the part. If not thoroughly removed by some reliable cleaning process, the cleaning media will be ingested into the engine’s intake or oiling system or both. When this happens, the engine is generally destroyed.
