Cracked Liner

[Peetypug 5]

today i thought i would have a crack at stripping my bottom end (1st time i've ever done one and defo the last)

all was going well until i dropped a piston and liner

on initial inspection it looked ok so i set it to one side

i pulled the other 2 out and went to check them all properly

thats when i saw the bloody hairline crack in one (yep the one i dropped)

do i have to replace all 4 or can i get away with just the one

how much are they?

is there anything else appart from the bearings that i have to have replaced or checked over before i rebuild it?

any help will be greatfully recieved

id always replace them as a set just to be sure, you may also need to put new rings in to bed into the new liners but if your rings are good its often worth the risk of trying them out first. I have a set of mint liners in the garage but postage would be an issue in case of them getting bashed about. They could maybe do with quick polish though to remove surface rust on the bores, they have been stood for a year.

Also not sure if they have to be matched? I seem to recall my pistons being marked with a 'B', dont know if this matters with liners.

[Peetypug 5]

the reason for stripping the whole engine is to replace anything that could be worn (rings, bearings)

just pis*ed off with myself for dropping one as they are imaculate otherwise

gona take everything to an engineering place to get everything checked, skimmed and the new/used liners honed

how much would you want for them?

Gutted. I feel for you, I've done things very similar

 

You should be able to get away with just replacing the cracked liner Pete. The main thing is to have a matched liner and piston. Pug/Cit sell them individually but as a matched liner and piston set. There seems, on the face of it, no problem in doing it this way.

 

I really hope this has a happy resolution.

Id be open to offers as I no longer have any wet lined engines. But reading above not sure if that means you needing matched piston? I thought it was just rings matched to the liner.

[jim21070 2]

That's right Pete,

 

Strictly speaking, you need a matched liner and piston. They are, as far as I can determine, matched up at production time and spend their lives together.

 

That is how PSA supply them as spare parts. I was hoping to tell you how much a new liner/piston set would be but they're NFP

 

However, having said that, a good liner and a selection of pistons could be matched using typical figures to work out piston to liner clearances and you'd be OK I think.

IIRC, the liner and piston will be stamped A,B or C, As long they are matched, all is well.

Think i learned this from haynes

So should be pretty easy finding a decent used liner with all the discarded 8v's lying around these days....

[Peetypug 5]

so for example, if my pistons are stamped A, all i need to do is find a liner stamped A?

or a matched piston and liner stamped A?

or how about a different bottom end?

i may have access to a 70.000 mile engine (if i can get it off my mate)

just checked my pistons

they are all marked with a B

but i cant see any markings of any kind on my liners

[Peetypug 5]

been to 4 scrap yards in the area with no luck

which other peugeots/s*itroens use the same pistons/liners

i know the 405 sri and i think the Bx gti

any others anybody? please help

[Richie-Van-GTi 71 2 Cars]

mine are definatley B's if you want to give them a try. Can weigh them today to check for postage if you want.

[Peetypug 5]

how much do you want for them?

im gona ring a few breakers and get a price for a piton and liner as well

[Richie-Van-GTi 71 2 Cars]

make me an offer, as I said. they are pretty useless to me now

[brianthemagical 1]

i used the pistons of one engine and liners of another, not sure why, but they were both 'b' and have done 1800 trouble free miles since the rebuild.
