I believe the reference to o-rings was talking about flanged liners. So if you've got an o-ring at the bottom to hold any possible coolant back, and a flange at the top to seal against the headgasket, sealing back coolant and keeping combustion gasses in the cylinder, I don't see how an o-ring would be an issue. I'd certainly rather have liners that at least have it as an option.

I'm assuming that when people pin the liners with bolts they use the correct size. To say they might hit the piston as they are too long..... Well.
Yes, the weld will shrink. My bigger concern would be the depth of penetration into the liner. The 'pin' that is created with the slug of weld, is only as good as the point it fixes to the liner. I don't know what the shear forces are between the block and the liner as it moves but it must be considerable.
I've never felt confident using a screw thread in a shear force situation, which is why I brought up threads. The valleys of the threads act as points of weakness where micro cracks can appear and the bolt fails in that allplication.
I would be happier to see a smooth pin which is a great tolerance fit in a hole.
That would be the best of both worlds in my (not a real engineer) eyes.

just with out thread exactly, so when this plug weld cools it is not going to shrink, of course it is. and seeing as it is not fused to the hole (aluminium) that was drilled in the block, it will loosen.
hey why not use brass self tapping screws, screw them right thru the block,
don't worry about the length the piston skirt will brake it off on the down stroke.
fill up you torches and sharpen those drill bit, the cure is here

Just stop dude. Guys like you and armyrover are the reason I don't post here anymore. I'm out here helping people and doing writeups and economical fixes and giving people USEFULL advice, and you guys just act like ******. **** off.

imo this looks like a great idea for keeping a customer in thier car, if you tell them i can try to fix it for 1500 or you need an engine for 5k ( give or take) which probly means they will junk the truck then that 1500 looks like a viable option to me, if it works for a year or ten it is borrowed time anyhow, plus welding overhead sucks lol

King hyperbole here cant fathom easy fixes. 7k posts and still clueless. Talking about sleeving a block and don't know where the o-ring is in relation to the combustion chamber. Says getting your motor top hatted is "1500 out the door".

Looks like a viable fix option for me. Hell, I was at a land rover shop the other day and they charged a customer $1100 to change wires, plugs,coils and injector seals.
$1500 to salvage my slipped liner motor would sound amazing if I was that customer.

the only reason the combustion gases happen inside the bore is if you have a block with flagged liner.
Stock liners are not flanged, the head gasket dont even cover them,so therefore when you have a crack behind the sleeve (like most) the gases go into your cooling system pressurizing it.
that fact that all the sleeve were ticking in the engine says there was a problem at one time or you believe every rover ticks

The Darton liners with O-Rings are top hatted (go back and re-read the original comment). Top hatted liners definitely seal against the HG, and the O ring (that won't be seeing combustion gases) is designed to retain hot coolant, so again, what are you talking about?
And a moving, ticking sleeve does not automatically mean a compromise with the block wall. There are literally hundreds of instances where the sleeve moved with no compromise of the wall between the sleeve and water jacket. I thought this was all common knowledge?

as tom said IF you told everyone that this could get you a little longer fine.
It is not the CURE and if it doesnt work when the next big CURE comes around you wont be able to do it because your block will be trash.
Hey I gave the guy his props for trying, but "I" dont think tis is it.
And there is no magical O-ring below where he is plugging. Works over
