We missed doing this before rebuilding this engine.
I'm assuming that unless these surfaces are smooth, I'll have leaks, leading to problems.
The engine is on a stand, so getting to the work area is easy.
My thought is this:
Stuff an oily rag tightly into the port hole. With a wire brush or stone wheel, polish the flat surface that joins the copper gasket, hoping that the oily rag will catch any bits of grit.
If anyone has done this before, let me know what size stone wheel I should use, and possibly what grit.
I have had a lot of luck using JB Weld in that area, I goop it on and wait 48 hours and then filed it smooth running the file along the block, When I got done with the file work I then covered the file with 400 grit paper to smooth out any ridges I may have missed with the file . Has worked for me. Just a thought.
I have seen much worse seal and work fine, especially if you can get the glands to line up and fit into the manifold. However, a quick dressing with a file wouldn't hurt.
I would use the individual copper crush rings. http://www.mtfca.com/discus/messages/257047/318698.html?1351426017
I like the oily rag idea. Those ports look very much like the ones on my 1915. I cleaned them with a little wire brush in a Dremel-style grinder. I just cleaned, and didn't grind. That's all. I installed the steel rings and copper gaskets with high temp RTV. It sealed fine. No problem.
I don't think it looks too bad. To really do anything substantially helpful, you'd have to take a cut off the block face.
What I'm concerned with is the freeze plug looking like it's not been crushed tight.
Jerry, I wondered about that freeze plug, too. I've not installed a freeze plug, nor have I seen it done.
Is there a youtube showing how it's done?
I'd grab a 1/2 inch bolt and a hammer and flatten it some but that's me. :-)
