How much would it cost to repair a 4.6 block with a slipped liner?

will it slip back?

V8 Development charge about £850 to fit top hat liners. (You better check with them for the exact cost)

no idea, i've never had it done before which is why i was asking here

I would be looking at just getting the one cylinder treated, don't need uber performance.

Could also be a cracked block behind the liner?

I'm not sure that V8 Dev would do just one cylinder, they might not think that it is the "right way" to go about fixing a block. No harm in asking them though!

Yep the block is fairly likely to be cracked but that does not matter the repair will sort that out.

It makes no "odds" whether it can be slipped back, slipping it back will not fix the problem!

Hi
it will be cracked behind the liner, that is why the liner slips, this company sell top hat liners at a good price http://www.westwoodcylinderliners.co.uk/ and are very helpfull, most good machine shops can replace them for you. You may want to get the block welded, i actually makes no differance as the flange at the top of liner seals the block.

Do you know if more than one is leaking?

Have you had the bolck pressure tested?

I went to Chesman engineering who do V8 devt's work. They would do one liner but the cost was a lot higher than just the total devided by 8 due to the setting up of the block.

In the end I had 3 leaky liners leaking so I had then all top hat linered.

I'm not sure that you could just have one slipped/ leaky liner replaced with a standard liner. Your block would need welding with the posability of craking/ leaking again.

If you haven't yet I would recomend hot pressure testing the block to check you only have one faulty. If there is more than one then it would only be a little more to replace all.

I don't think i'll bother then, it's going in an offroader so it's not going to be revved hard like it would be in a kit car so I don't need that kind of outlay on the engine.

Thanks for all the info though

Just wondering, is there anyway to check if a liner has slipped without the engine running or is it easily visible?

Apparently you can feel a small step between the liner and the surrounding block on the deck surface.

Of course the block could have cracked but the liner has not slipped, a pressure test would show this up.

The only sure fire way to prove a cracked block is as already stated, to pressure test it. There's a few threads on DIY efforts to do that.
