Slipping liner - how long?

[expectthebest]

Is a slipped liner something that can be driven with as long as you don't mind the noise or is there a point where it renders the engine inoperable? Is the knocking really loud or is it just more of an annoyance?

My 03 has 115K miles and has been doing it since 35K miles. It more of an annoyance than anything, plus I can only hear it when idling/windows down. It has not done any damage to mine by driving it.

Mine had the knocking since about 65K, replaced the HG at 115K and totally went south at about 132K. I would suggest driving it till the thing falls apart.

On a side note, my car is an 01 Discovery, I bought it with 46K in 2005, it had the engine replaced at 40K, by the dealer with a factory replacement.

As far as I know you can drive it for a very long time as long as you don't mind the noise. I haven't seen any actually fail because of a slipped liner.

Interesting. I thought the 4.0 engines didn't have the slipped liner issue.

I have heard of numerous 4L engines that have suffered from slipped liners. But the 4.6L is more prone to them. The first link is very interesting, and the second link is for an eBay listing from RPI, the description of the problem in the Land Rover Casting of their blocks is an eye opener.

Yup, a new engine certainly is expensive.

This is also not a cure for loose liners either because the steel liner is designed to expand under high temperature within the aluminum block and its with extreme engine temperature that the top hat effect of such replacement liners will often become detached, ductile or otherwise.
Dont then be fooled, if such a simple fix was appropriate Rover themselves would have used it themselves and saved a fortune from the cost of paying for new Casted blocks on an already redundant production engine</H7>

Wow. What a lot of BS they spout.

RPI were all over top-hat liners before they jumped into bed with MCT (who are making these blocks)... Also worth a note - several of the companies that do the re-liners in the UK have already re-worked the magical 'coscast' blocks with top-hats.

So, is a slipped liner really fixable?

 

[turbodave]

In so far as you remove the offending liner and machine the block before installing a flanged / top-hat liner - yes - totally fixable...

PTSchram has also shared his thoughts on pinning the liners before now as well.

 

[expectthebest]

I'll do a search and see what I can learn from PT.

Ya know, with all these ? about the 03 d2's .It really shows that your unsettled with them. My advise would be to stay away.. You allready know they can be a pain in the ass.
Get a low mile D1 and smile!!!

make sure it's not a cracked flex plate...

My well maintained 98 D1 4.0 with 108K went just over a week with a slight tick before the liner slipped far enough to grenade the engine. What came out of the oil pan can be seen here: http://bahnstorm.com/rover/engine.htm

I put part of the blame for it not lasting very long on it happening on a really cold sub zero morning shortly after startup, but once the problem starts I think, overall, it is a crap shoot on how long it will last if it is a slipped liner. So if you don't mind replacing the whole engine might as well run it till it breaks.

Ok, so I've done some research by searching threads on this site. It appears either new top hat sleaves or pinning the sleeves will work without having to replace the engine. So, what is the cost involved in this?

you pin the liners before they fail and you top-hat the block after they have failed.

In my opinion once the liner has slipped, the engine is done. This is my opinion, the liner slipped because the cylinder wall cracked, and it's letting coolant in between the sleeve and the cylinder wall. If this is the case, top hatting will not allow the coolant to make it's way to the top of the engine, instead it will go down to the crank/oilpan area. Just my opinion.

If the block is cracked, top-hatting will do nothing unless the crack is welded first.

Good Point!!!
