Super C Chipped Block - Is It Ok?

Hey Everyone,
I am right in the middle of my first tractor engine rebuild. Pulled a completely frozen and abandoned 53 Super C from a farm, and finally managed to get all of the pistons out, and all of the sleeves out except for 1. Engine is still in frame.
After I moderately cleaned things up, I noticed this chip in the lower portion of one of the sleeve bores, just above where the lower gasket sits (see pics). The gasket popped out and is actually not damaged at all, don't know if that means anything.
Before I ask the question, it should be noted that rebuilding this tractor is purely for fun and it will not be used for actual work. Just want to eventually start her up and drive around...
So, is this a lost cause or is it worth installing new sleeves and pistons and rolling the dice with this chip? Is there any way to repair this, with a jb weld type product after I place the new sleeves in?
Thanks in advance for any responses!

I think it will be fine as is. There is down pressure on the Oring, and down pressure on the ring when installing the sleeve. Jim
 
It allmost looks like the metal never got to that spot. I would run it as is. Lube the Orung with A smere of dish washing liquid to assist sleeve
insertion. Jim
 
dont see any problem there either. just make sure the o ring sealing surface is good and clean with scotch brite and lube o rings with dish soap or brake fluid. absolutely don't use oil on them. u can always check the job for leaks once the sleeves are installed. fill block with antifreeze, close to sleeve tops. and let sit over night with cardboard under engine. I say antifreeze because it is more prone to leak than straight water.
 
Hello nice guy, welcome to YT! I agree that this would probably not cause you any issues.
However, if it would make you feel better you could fill in the defect with JB weld or the like. Clean
the area real good with a rotary wire brush probably want to get that cast primer/sealer off of the
area. Clean it up with a shot of carb cleaner or acetone. Cut a piece of milk jug to fit in the o-ring
groove, wedge it in there with match sticks. But before you stick it in there rub it with candle wax
so the epoxy won?t stick to it. I would over lap it around the edge of the defect 3/16 - 1/4? about a
1/16? thick on the overlap part. After it is set a little touch up in the groove with a cut off wheel or
Dremel and you?ll be set. Good Luck! Rick
 
If it must be filled. Just grease the old 0-ring then do your J B weld deal, and pull the old o-ring out when set. Polish the edge to fit the sleeve and go. I don't believe there is anything to to really worry about there. Since it is such a small place. As already said there will be pressure down on it and, you could fill almost full of antifreeze and let set to see if it does leak.
 
Thank you everyone for your replies and input! Once I have purchased the new sleeves and pistons I will post with an update on whether or not she leaks. The more I think about the jb weld idea, the less I like it. Seems like when I install the sleeve any pressure on that little piece could be enough to chip it off, or at the very least have a piece that is susceptible to coming off and floating around the water jacket/cooling system after everything is back together. That being said, I really appreciate the milk jugg idea for a mold - that will be my backup plan.
Thanks again!
 
I would install that sleeve first so I could put some sort of sealant on the area from the adjacent sleeve hole. Maybe that white stuff that you're supposed to put on head bolts that protrude into the water jacket?

Hey Barnyard, thanks for your input! Would you be at all worried about that sealant coming loose and flying around the coolant system?
 
I think it will be fine as-is. If I am not mistaken, the Super C sleeve have a bottom shoulder on them. The o-ring is clamped between this shoulder and the block. The sleeve is inserted from above, and held in place by downward pressure from the head. The o-ring is sandwiched between the sleeve shoulder and the lower lip in the block. If the chip was in that lower lip (visible just behind or below the chip), I would be concerned.
