582 cylinder sleeve crack

I paid a visit to the machine shop and surprisingly the owner put up little resistance and offered to fix it for free by sleeving the offending cylinder. Here's my question: if a cylinder has a water leak in the cylinder wall the leak must go through to the water jacket; how, exactly, does a sleeve help with crack control in this case? Should I be concerned with the sleeve or should I take the angle that everyone would be saved a lot of potential headache by starting with another block?

Perhaps this time actually keeping his eyes open while Magnafluxing so cracks are seen. Knightgang Lieutenant. Joined Oct 6, Messages 1, Re: Sleeving a cylinder with a cracked wall? Stev, you said it was a block supplied by you. I am not taking his side here because I feel your pain and feel that he should have found the crack before building the engine.

However, if he had found the crack prior, you would still need to find a good block to have built. I would try to find another block and puch to have him build it using the parts from the existing block without charge. Short of that, you will have to accept the sleeving. I am not sure how that will solve the water issue unless he welds the sleeve top and bottom.

Then he will have to rebore to smooth out the bottom of the cylinder I suppose it can work. I have heard of several engines in cars being sleeved, but not sure of the reasons. Good luck Joined Sep 9, Messages 3, Nothing wrong with a sleeve if it's done right, an interferance fit and additional sealer something like locktite assures against leakage, trashed cylinders get sleeved everyday.

If the crack gets is into the deck then I guess the head gasket seals it I'm not sure now that you mention it? Bondo Moderator Staff member.

I have seen rare vintage blocks with cylinders blown out and chunks missing being restored with sleeves, it's the internal webbing that strengthens the block not the cylinder. They cut the cylinder leaving a step at the bottom as a stop for the sleeve, the top exess is then machined to the deck.

I hairline crack can go undetected easily if nothing was suspect and block wasn't magnifluxed, you would think they should have magnifluxed it.

Quick Shop. Length Quantity. The new engine will also have an LRE custom solid roller camshaft, Diamond pistons and a Callies crankshaft and Callies connecting rods.

The shop is also still utilizing a PTC converter, a TH transmission and the Madman suspension from the prior build, but will be building a new, custom set of headers. Tech Center.

Jan 12, Looks a lot like digiphobia to me. When I see numbers it always freaks me out more than just looking a analog dials that don't exactly line up. I bet that difference wouldn't be a needles width on old school analog gage. I see a bigger spread at the lower EGT's which is prolly due to carb imbalance at idle. At higher throttle and EGT you seem to be within about 50 degrees. Sync the carbs at idle and then make sure the slides disappear out of sight at exactly the same place at full throttle and that will be about as good as you are going to do.

Posted 20 Apr You could maybe put a thin washer under the one needle snapring keeper to make that side run just a bit richer. But I agree with Chris, 50 degrees isn't that much.

Maybe even reverse the probes the see if the reading stays the same. No guarantee the probes read exactly the same either. Posted 16 Oct I agree with Chris. I have been watching my EGT's real close lately do to high readings. The EGT's run different in some areas and pretty close in others.

I would not think one thing about a 50 degree difference because mine shows that much variant consistently. There are so many possible variations between all the different systems. If you want them exact I would try Jimchuk's trick and add a thin washer under the needle snap ring. Do this to the carb that feeds fuel to the cylinder that is producing the higher EGT reading.

I would start with a thin AN washer or make one out of shim material or thin aluminum plate like 0. Just make sure the washer is the same outer circumference as the needle snap ring. You don't want the needle setting crooked and catching on the edge of the Jet Needle after you go full throttle.
