Engine Gasket Surface Preparation

Engine Gasket Surface Preparation
To ensure engine gasket sealing, proper surface preparation must be performed, especially with the use of aluminum engine components and multi-layer steel cylinder head gaskets.
Never use the following to clean gasket surfaces:
^ Never use a metal scraper.
^ Never use an abrasive pad or paper to clean cylinder block and head.

^ Never use a high speed power tool or wire brush on any gasket sealing surface (Fig. 1)

NOTE: Multi-Layer Steel (MLS) head gaskets require a scratch free sealing surface.

Only use the following for cleaning gasket surfaces:

^ use only a plastic or wood scraper (Fig. 1)
