Hi All,
Just took cylinder head off Cb350f due to 2 maybe 3 new spark plug threads nead a re thread, and had a few problems removing it, this is why.
The PO had used a silicone gasket maker on top of the cylinder head gasket and it “super glued” the cylinder head on....any now the reason why they did this become apparent when I managed to get it off.
The face where the gasket sits is damaged and I’m presuming the silicone was put over these areas to provent a leak, in fact I had no leaks at all. The damage does look a lot worse on the photos though.
Is this cylinder head repairable ?
Looking at the valves the engine has been running rich so needs a good decoke, the exhaust valves have a mark in the middle of all of them, ( see photo) what is this due to or is that how they are meant to be.
And finally if it’s saveable does anyone no where I can get the work done, West Midlands, Warwickshire area but don’t mind travelling or posting out.
Hope I’ve explained everything ok.
