Today I removed the old engine exhaust to exhaust leg gasket and will use a new one. Also opened up the exhaust cooling to check for corrosion and after cleanup the plate has numerous small pinholes that are not deep. I saw one larger area that could be corrosion. The two arrows on the tape in the photo point to it. It is maybe 0.015/0.020 inch into the material. The plate is (looks like) made of aluminum that is 0.093 thick before forming. So I will replace the exhaust cooling plate gaskets and put it together. I plan to use 3m 847 to seal the cooling plate gaskets . Does that seem reasonable?
Thank you.
