I am doing a top-end rebuild on a Toyota 2GR-FE engine that includes resealing the timing cover, camshaft housings and upper oil pan. All of these surfaces are a “polished aluminum” that are as shiny and smooth as a mirror. There is no cross-hatching from the factory.
What is the best way to fully remove all of the old rtv? I generally use lots of plastic razor blades followed by a small piece of red scotchbrite (by hand) to remove any remnants. However, I think the scotchbrite will dull the finish here.
Here are the results from using only plastic razor blades:
As you can see, there is still some rtv embedded on the surface. It almost looks like staining at this point.
What is the best way to finish cleaning this?
