    Clean the engine front cover using a 3M Roloc Bristle Disk (2-in white, part number 07528) in a suitable tool turning at the recommended speed of 15,000 rpm.

    • Thoroughly wash the engine front cover to remove any foreign material, including any abrasive particles created during the cleaning process.
  1. NOTICE: Place clean, lint-free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages or the oil pan, may cause engine failure.

    NOTICE: Do not use wire brushes, power abrasive discs or 3M Roloc Bristle Disk (2-in white part number 07528) to clean the sealing surfaces of engine block, cylinder heads, and oil pan. These tools can cause contamination that will cause premature engine failure. Remove all traces of the gasket.
