    I want to know if it is possible to resleeve a cylinder on a 4 Cylinder block?

    Because my number one cylinder looks like it has a hair line crack in it but i i'm not sure yet but i'm goin to have it checked to be on the safe side.

    Any info would be gratefully Appreciated

    The "Iron Duke", this I4 engine has an iron block; and, I think the addition of a sleeve is normal repair for this engine (of course, that depends upon the size of the crack you are trying to fix.

    The sleeve needs to go in from the deck (top of block) and is held in place with a grove cut into the top of the bore

    it's just a hair line crack about middle way's in the number 1 cylinder. and I'm worried that is where the water is getting in to my oil at but i'm not sure unless i can find someone to test and see how bad the crack is.

    It's possible to do, I havent heard of a shop that does this type work in a long time, its not economical to do any more most shops just replace the block.
    But I'm sure if you spend a little time searching you'll find a quality shop that can do the job.
    In one of its old versions that engine block was sleeved from the factory to cut down the displacement, dont remember what vehicle it was used on anymore though.

    yeah i been searching the internet and haven't found a shop yet to do it. But I'll keep searching and i might find one if not I'll go to pull a part and pull the best looking block out of a junker.

    Here is some pictures of the crack in the number cylinder. it's just a hair line crack but it's got me puzzled how it got there. i cleaned it best i could with a wire brush on a drill.

    Most shops don't wanna mess with a cracked block any more. It's to labor intensive, meaning expensive, to do. Especially when there clean, rebuildable blocks littering wreaking yards all over the country.

    That's definitely a crack. If I were you, I'd start looking for a junk yard engine and replace that block.
    Good Luck and God Bless

    well every junk yard i called or went to they don't have one. and Trust me i been to pretty close to 150 junk yards in Tennessee and still haven't found one yet. and when i do find one it was either had a busted block or a slung rod. but anyway i found a place in Maryville Tn that does resleeving for 75.00 to a 100.00 and that's bead blasting it clean and everything.
