Getting all the ports and cavities of newly machined engine blocks or manifolds can be difficult and time consuming. With today’s tighter cleaning specifications, meeting cleanliness requirements is a challenge for manufacturers. We designed this engine block rotating washer to use solvent-free, aqueous technology to remove oil, grease, paint, carbon, and gasket material and clean engine blocks from the inside out, including all hard-to-reach bores and passages.

Challenges of Cleaning Engine Blocks
Engine blocks are among the most critical components in any internal combustion engine, and impeccable cleanliness upon manufacture or repair is necessary to keep them running optimally for years. Our engine block washers are engineered to deliver exceptional parts washer performance, with as little waste as possible in terms of time, energy, or personnel involvement.
With this parts washer the engine block is rotated back and forth during the cleaning process, and the washer stops at certain locations to allow a spray lance to go down into specific ports for a more thorough cleaning of the block.
By continuously turning the engine block during the cleaning cycle, every nook and cranny is exposed to high-pressure jets and cleaning agents, and the engine block is cleaned to specification and ready for assembly and immediate use.
