Title: SEaling Washers - Copper
Post by: Eldrick on June 25, 2024, 09:19:23 AM
I have twelve washers in the cylinder head, I belive they are copper. Two of the twelve have a (rubber) gasket built into them. When I put the engine together again should I replace all twelve washers as they look like compression seals?

You can aneal the copper washers and use again if you haven't got replacements. The 2 with rubber in them, Dowty type washers, it's best to change them.

Make 100% sure they are actually copper washers before trying to aneal them. If they are the originals as fitted by Honda they are steel with a copper coating and will not aneal. Best way to tell is to scratch the surface with a scriber first.

A magnet might help - the copper ones are not magnetic.
