Mating Surface Prep
Fully Prepped Mating Surface
Here's a close-up of the engine block deck surface after the final cleaning process. After cleaning with scraper and rag, use a wire detailing brush (powered brushes and cleaning pads are too aggressive as I mentioned earlier) to scour the surface until all left over corrosion, gasket material, and sealant are loosened. Once loosened, use a clean rag with cleaner to wipe it completely free of contaminants. Although time consuming, this process ensures a proper seal once you go to reassemble your engine.
