I have a new to me 1986 Seville. It has a Mercruiser 3.7 170 installed. The engine ran when I purchased it but it obviously needs some TLC. I know these engine have a bad history but I would rather try to address what I have than put something else in. Having said that when I pulled the exhaust off as part of pulling the whole engine I found a crack in the manifold INSIDE. I have attached a photo of it. The crack doesn't seem to extend to the outer part of the riser. My question is does this crack cause issues? Does it need to be repaired/replaced? Any thoughts are appreciated. Thanks in advance.
