Default Scratch on deck of ls2 block repair





I'm wondering what I can do about fixing it. Is there anything?

Thank you for any help.

Man that couldnt hardly be in a worse spot! The only way to fix it I see is to have it welded and then decked!

I know the spot is terrible. How much would a repair like that run? Any guess?

The scratch doesn't even grab your nail on the sleeve itself so I doubt that it would need re-sleeving.

Yeah I've heard of the jb weld thing but I'm not big on jb weld personally. Is there any type of solder type material? I know it sounds crazy but I just thought there would be something like that out there.

Also how does the copper help?

I don't know how much they would have to take off the deck to get rid of the scratch. I wish there was a way for me to measure it.

As a last resort, the JB weld may work. I don't know if the heat will exceed it's limitations, but a small fill, scrape off the excess and hope for the best. Does the O-ring on the MLS gasket sit right on the damage or outside of it?

By the looks of it, I don't think a mill will even take it out unless you mill a lot. The picture makes it look pretty deep.

i think the jb weld would melt. had a buddy that used it to seal the are where the igniter went into a potato gun and it melted and dripped on his hand the first time he shot it!

Take it to a reputable engine machine shop and they will tell you the right way to fix it and how much it will cost. I doubt they'll use JB Weld.

Thanks, unfortunately I don't know of one in the immediate area and I wouldn't be able to get to one any time soon so I'll keep hoping someone here will be able to give me some more helpful advice. I don't plan on using jb weld.

I just saw the new pics. Looking at the last pic that is taken directly over top of the nick, I wouldn't worry about it. You have enough surface on both sides to seal if the deck surface and head are flat. If combustion gases or coolant make there way to the nick they would eventually make there way to the other end.

" If combustion gases or coolant make there way to the nick they would eventually make there way to the other end."

I'm trying to understand this part. Can you elaborate at all?
