Just had the head of the metro for the 1st time,It still has honing marks in the bores and no ridge at all up the top*surprised*,the car has been 106K but only on normal 3-7 psi boost.I've been running it at fixed 8 for the last 500.
Block is believed to be the origanal 1989 so linered.

Wonder how long they take to wear out*oh well*

Dunno mate but my 16valver block of choice has liners, though, low milege. If its good bad, don't know but I can still use standard size pistons which no one wants these days*wink*

The linered block is a WFM numbered one,I have a non linered turbo block I stripped that had an approx .003" ridge at the top.
so take it the liners that rover fitted are well hard spec

I don't have the same experiance at all. The A blocks I've dismantled with known milage has got exactly the same wear as the A+ ones. I do not think that the material has changed much. Infact, Vizard states that the A+ block are made of inferior material than the A ones due to cost reduction.
Rods are inferior on A+ engines as well.

80ies were the cost reducing decade, and just bacause some bearing or journal became bigger on the A+ does not mean it's better, just cheaper.

Not talking about A and A+,The block I have is A+ from the time they(alegedly) had casting problems and instead of chucking the blocks,rover decided to rebore them and fit liners

what can you rebore the linered blocks to?

same as std? or would a 1380+ be out of the question?

+.040" I think although I have read that they don't like boring them as they are hard

Near Daventry, midlands

most places will turn your linered block away as they are much harder to rebore, +40 is also a bit sketchy as it leaves a very thin liner.

I also have a linered turbo block here which is similarly unworn, cept the pistons have det marks and one of the liners is scored. Have to admit, its tempting to swap out my planned daily engine rebuild and use the linered block

I've seen the future and tbh its Pie

As far as I know, you can take linered block to 1380, but you need to remove the liners first :)

No, I don't hate A+ stuff, the valves are excellent *wink*

My views on A+ stuff are based purely on experience. Might be a coincidence, might not...

Linered blocks not the way to go.

If you look at steel liners under the microscope, they are pretty smooth, whereas cast iron is little bally things. Cast Iron creates a better oil film than steel. This is better for standard rings.

Uprate your rings to super duper chrome jobbies and I expect it all lasts forever. I had this conversation with an old engineer/mini racer who said there was a catch. It may have caused it to run hotter or something. There was a catch and it was better to stay iron over steel.

Anyone back it up/dismiss it?

Are the liners steel? The ones I've fitted recently have been iron.

The only backside on liners is that if they don't have a proper collar on top, this might cause some headgasket issues on the A-series. Seen it a couple of times.

Downside? Vegard.

I have had no problems with the liners I fitted to the 16v. I did however have them fitted such that they sit on the original bores at the very bottom, that way, they wont move up, nor down. Infact you would be hard pushed to determine whether liners were fitted

I've got one A block with liners with a heavy ridge, out of a Riley, smoked like a pig.

I run a supercharger and I don't care the TB is on the wrong side.

I have an A+ block which is linered and needs boring to +40 to clean it up to be of any use. Minisport refused to bore it to 1360 because they said it was already beyond that if the liners were removed so I,m now confused by the earlier assertion that a linered block can go to 1380.I have never heard of steel liners, either.
