SA 250 Perkins question

[JFwelder]

Hey everyone... New to the forum. I searched around but couldn't locate anything for my question. I just bought a 1988 sa250 with the 3 cylinder Perkins motor in it. It ran and welded great except I knew it had blow by. It was getting back pressure and coming out of the dipstick port and breather tube. I was told it probably needed new rings. So I bought new pistons and rings. Broke the top end down and pulled the old pistons. Two cylinder sleeves have pretty decent scars in them where a piece of the old ring ground into it and the piston. I had planned to have the motor done and the machine in my truck already so I could go back out and make some money.

So my question is if I don't pull the block and have it re sleeved or bored out enough to get rid of the indentions and just hone them and slap in the new pistons and rings what will be the result? Will it change the amount of blow by? Not blow by at all? Or work good for a while and then fail?

If it will last me a year then eating the 300.00 for the new pistons/rings getting ruined isn't that big of a deal to me.bc the sleeves are already bad anyway. If it won't then I'm throwing the money away for no real gain. So I'm torn on what to do and this is the first time I've ever taken an engine apart so not sure what to do at this point with time being an issue. I know that it should be re sleeved yes... But can I get away with it like it is is what I want to know.

Any help or advice would be greatly appreciated.
