SV-LAP Sonic Cleaning of Housings Sonic cleaning is the best method we have found for cleaning the lapping compound from housings, including clearing the water and oil passages, although they need a LOT cleaning by hand before you assemble the engine. Price is per side housing - three required per engine. This is very cheap insurance for a new engine, and mandatory if there is any reason to believe there is trash in the cooler. Many new engines have been ruined from the metal filings remaining in the cooler from a previous engine failure. Keeps the rotor from contacting the side housings.
