Same here, about 1/8 of the skirt was missing from the piston in the dropped cylinder and was in the oil pan.
Out curiosity what cylinder did you have the drop on? This engine it was #2.
Below are photos showing how far it dropped and from the inside where it broke apart causing the catastrophe.

Mine was #5 but also a 98 LSE. I think it happened around 165-170k. The liner had dropped about the same amount in mine. The original head gaskets looked good.

Wow so it dropped far enough down, the piston rings grabbed the ledge and crap exploded. Pieces everywhere. Great failure! Pin the liners before this ever happens if your dealing with this and buy more time!

This is really interesting to me. These 2 engines are the only 2 GEMS engines I've ever heard of doing this. I looked at the pictures. I wonder if either one of those had engines replaced during the Bosch years under warranty.
When this thing was making the knock sound was it misfiring?

Mine was a lease return with 30k on it when I got it in 01 so I'm pretty sure it was the original motor. It still ran decent around town but I had trouble getting over 65 and it was real dog. No misfiring and the only code I had was for a downstream 02 sensor that remained after replacing the sensors and the later engine. It would make a random ting ting ting ting ting like there was a bell in the engine (it would usually do it 4-5 times) that would come and go.

This one is out of an LSE as well. Im told it ran fine, never bothered to try. Sent it out for top hats, should be getting it back next week.

That thing looks like it's been sitting outside in the rain. But I thought the GEMS engines didn't do this. How common do you guys think this is? Who's top hatting your block ?

Ive never heard of a GEMS engine doing this until I removed the head of the one in the picture, so Id guess not common. Would be interesting to compare block serial #s. Id bet LSEs were all built at the same time to minimize having to keep chrome crap in inventory, so they’d likely pull engines in a small range of serial #. Someone probably f’d up in the manufacturing process around that time

Thats an interesting theory. I missed that about them all being that goofy trim level. I believe they knew how to tell the good blocks from the bad ones. They say that the LP Range Rovers got the best blocks. Maybe when they saw the chrome they gave the bad blocks to those LSE's.

Funny you mention the manufacturing process. I'm told by someone who toured the assembly plant that the casting of the block would fall out onto a dirt or sand floor and a guy with a massive leather mallet drove the liners into the block before it cooled.

When I first arrived here in '00 one of the first things I learned was at all cost don't let your engine overheat because a slipped liner may well be the result. Not as common in the GEMS but happens. Some will argue its not a slipped liner but that the block develops a crack that, over time, allows the liner to slip. That seems like splitting hairs, and I'd point out, the engine continues to run until the liner drops. Then not so much.

Let me qualify this by saying, although I have turned a wrench on many different kinds of equipment over the years, when you move into the internals of an engine/transmission that's beyond me. Don't necessarily like it. Had to do it because of my job. Never wanted to go there. I only know what I've read over the years on various LR sites, mostly here.

so you took the engine out of a jeep one time and now your an expert.

I'm still trying to figure out how you did that whole act without a net and no ban hammer. What was it...My uncle owns a cock farm but he doesnt keep chickens? Or the shock and amazement when you and Josh found out cock fighting was about roosters.

Well that and.... having spent 30+ years as a golf course superintendent doing repairs, including in the field, of JD, Toro, Jacobsen, and other brands to numerous to name, fairway units, greens tri-plexes, walking greens mowers, sprayers, utility vehicles, blah, blah, blah. For fun try climbing under a fairway unit that has blown a hydraulic hose with fluid everywhere, with the hose woven through every nook and cranny, in 95 degree and 60% humidity weather. Or climbing into a hole where a 4" line (that carries 400+ gpm at 125 psi) that tees into a 3" line one way, and a 2" line the other way, and get it all cut apart and reglued in a time frame that allows for irrigation the following night.

Then why do you say so much stupid shit? Is it because your dehydrated? Well you added some shit there, I would not climb into a hole like that for what they pay you.
