2seater Posted June 17, 2022 Share Posted June 17, 2022 I never saw a front cover corrode like that. Intake manifold galvanic corrosion is not uncommon. What did you do to repair? Link to comment Share on other sites More sharing options...
Guest Posted June 17, 2022 Share Posted June 17, 2022 I removed bad material and used a epoxy product as a filler. It's been working for now, I've had good luck with the epoxy but if it fails I will replace. Link to comment Share on other sites More sharing options...

I flushed Coolant and it's was very brown so I'm thinking acidic??, I don't know the exact cause either but for some reason it is almost always where dissimilar metals are in close proximity, and aluminum alloy is generally more reactive. I do the same to repair erosion👍 Link to comment Share on other sites More sharing options...
