Do Cylinder Sleeves Really Slip?

Yes , they do slip. I have one in my garage that has. The #7 cylinder , for what ever reason, sleeve slipped down just far enough to allow the piston rings to expand over the top of the sleeve and on the down stroke of the piston it broke the top of the piston off in 3 places, spewed alluminum chunks back into the intake tract...fouling 3 other plugs. Amazingly enough though...the engine still ran ( obviously REALLY rough )and I made it home 10 miles / started it the next day and drove it to my shop 15 miles from home to yank out the engine. It had 175000 mi. on it at the time and had never been overheated in the 60000 miles since I owned it. Someday soon I'll try to get some pics of the carnage for all to see.

xceller8. the article is saying that there is the ridge that prevents the liner from slipping starting in post 2000 models. was yours a post 2000 model or are you talking about your 98?
i'm with you oysterhead. i'm not seeking the answers for myself as much as us as a forum coming up with the correct conclusion on this. i'm wondering if the confusion is in the fact that LR seems to have made a slight change in the block design post 2000, adding a ridge at the bottom of the aluminum cylinder preventing sleeve slippage. this would help people not to consider a slipped sleeve when trying to diagnose a tick or a miss or exhaust in their coolant, ect.

So all this talk about '04s slipping a sleeve is rubbish. It's really a crack behind the piston sleeve...but did I miss something or is the article a little inconclusive about the cause of the crack? Just poor design when relative to the head bolt it sounded like.
Sad thing is, the flanged sleeves he recommends cost like 4k to install and it's hardly worth it at that point. Better off buying a new block with tapered liners it seems.

Slipped liners
My thought is to replace the motor if the block is damaged and possibly go the route that Bbolin did using the Turner Engineering motor. If it ever comes to this I would rather replace it using a source that has bettered the design and are more familiar w/it.
I don't want to think about installing a used block and having the potential situation repeat itself in the future. Reading about the Turner motor does not sound bad with the design and improved MPG w/the gas flowed head. Of course I have not had to deal w/this situation yet as my Disco falls in the bad Vin# range sitting w/47K miles on it.

I think what normally happens is you have exhaust in your coolant and most mechanics would say it's a head gasket problem. so you go ahead and get that done. if your smart you pressure test your heads and have them machined. if all tests good there the next conclusion would be pull the block and pressure test it.
one the block is out, you have choices. replace the engine, just replace the block or install some top hat sleeves.
