How I fixed my Land Rover tick (slipped sleeve)
#81
The problem is that the liners need to be chilled and the block heated so that they can be pressed together properly. Plus, the work associated with properly cleaning below the liner to allow it to be properly seated would be somewhat involved, not to mention the fact that the newly machined block would have such a lowered deck height that you would need custom head gaskets to keep the compression down where it need to be and put the intake ports at the right height for the intake to line up. For the effort invloved, I would go with top-hat liners and be sure of the outcome.

Pushing the liner to the register would be quite easy. It's not hard to do with the proper equipment. Depending on the depth of liner movement downward, a .020 mill on the deck is negligible. The link provided to Cometic would provide any gasket thickness within your needs.
Cometic Custom Gaskets
Available thickness: .027", .030", .036", .040", .045", .051", .060", .066", .070", .075",
.080”, .086”, .092”, .098”, .120"
Milling the head for proper intake alignment is old news and been done for all makes and models of engines. I am only offering this as an alternative for others to ponder.
La Sleeve Top Hat Part number Rove 1 $680.00
Machine and bore block / Hone $1300.00
If viable, I would be certain that it would be less than the $1980.00 for just the sleeve installation. I guess you could pin it as well, but that would be a last resort. Those figures are what it costs now for parts and labor.

Thanks Rudawski. Information like this is what keeps me sane when wading through internet bull.
Just bought a disco with this problem. I'd like to know how many miles people have put on after this fix and if there have been any problems.
I will be doing the fix in the next week or so and will report results.

Well I installed the pins this weekend. Should have everything buttoned back up tonight so I can start it. I'll either be celebrating or writing a 'part out' ad. Wish me luck.

Update: Started the truck last night. NO MORE TICK! Idled for about an hour total and drove for ~ 50 miles. Quiet as a mouse. Thanks again Rudawski.

Almost all aluminum blocks have cast iron liners installed. The exception is blocks where specialized treatments are used to make the material within the cylinders hard enough to withstand the friction from the piston rings (such as Nikasil). I think the Acura NSX had a fiber cylinder liner, but cast iron seems to be the cheapest way to go. I don't think steel works well because of it's thermal transfer and expansion properties.
