Is Engine Case Shot, Case Assessment Options

[Costa05]

Wanting opinion from the engine builders here. Is this case shot now with this metal gouges on the barrel mount? Piston was completely rusted solid in the barrel so had to cut the rod to get it off. Woops!!@$@*

For the ID of the hole, I'd work the metal slightly with a small hammer then run a bearing knife , single edge or similar around the ID to clean up any loose metal. I would not try to remove metal in an attempt make it smooth again, all you need is for the barrel not to catch.

For the sealing surface face I'd tap down any high spots, scrape off any loose metal and leave it at that.

The goal is to reform metal not remove it.

You would only be carefully removing the high spots,I didn't say to hog the area out with a file ??? (IMG:style_emoticons/default/rolleyes.gif) (IMG:style_emoticons/default/rolleyes.gif) .
McMark recently did the same sort of thing on a damaged piston...he knows what he is doing.

I said to tap down high spots to reform then remove loose metal by scraping. ( IE flakes )

You only said to remove metal. " No,that area could be cleaned up with a small half round file. "
