I`ve seen valves much worse than this.
My concern is the visible ring-shaped marks.
Probably left by the gasket around the perimeter of the sealing surfaces.
What else do I see? I can see some pitting and probably some wear marks that might have been caused by a broken or disintegrating glowplug tip IDK.
The chambers dont seem to be loose and are sort of `flat` and level with the surface of the cylinder head.
Again, thoughts and ideas, suggestions are very welcome.
Have you seen much worse? Have you reused something like this?
Would you and is it even worth the try?
Those marks tell some stories.
On cyl one near the valves area, I can feel the circular marks` depth by my fingernail. Not very deep but I can feel it, it is not only visible but is really there.
The burnt area/pitting of the chamber tells something too...
but that surface looks very bad only in my picture, not horribly bad in real life. They don`t appear to be cracked or worn through but I cant see them from the inside though. I have a 2mm camera so maybe I should.
Thanks for the ideas and checking through lots of pictures!
PS. some of the piston tops show `light kissing marks` from the valves. Not a huge collision but they are present on 1 or 2 pistons. I need to clean the bottom up too.
