...how?
I have just been told by the guys who were honing my 70k XE block that the lip on the pistons is too great to do anything with and they need a rebore.
I have got some 20XE 86mm vaux/mahle pistons for it, and now i have no use for them because it needs a rebore, and that means the best part of £500 worth of accralite pistons and bits.
Is there anything else i can do? Any other way of working it??

Get another block or one with little wear that just needs a hone.
I would rather lose by a mile because i built my own car, than win by an inch because someone else built it for me.

yea, this is the 3rd block i've had checked over. they are all buggered! I'd have to find one that has done less than 50k or been looked after uber well.
Is a pain in the arse!

I think you should just go the £500 pistons route, least then you know its perfect, also it will be hard to find a good block without going round with a micrometer.

yea i know...
If i get those pistons though, do i need rods too, or can i use standard ones (considering it wont be getting too much abuse). Also, do i need to get the whole thing lightened and balanced?...
then it really starts tottin up!

You need to watch if you get another block as they might be matched assemblies.
Accralite pistons will work fine with standard rods. And the pistons from there should be weight matched pretty good, there will probably be more tolerance in the standard assembly. You don't need to get them balanced.
Where is the lip on the piston? Or do you mean a lip on the cylinder bore?

Cheers for the help guys!

You can get oversize rings if you get a slight rebore.

My one was rebuilt 1000 miles ago, still burns a very small amount of oil when very warm - would that be because of this?
Was a very old tired lump before rebuild

right.....ive just done steW and spONams xe's.
steW's block was on the limit of what you would use again with a hone and re-ring. after that obv rebore.
spONam's 1st block was well and truely fucked number 2 had a lip not even a 88mm overbore would clear.
he found a block that most people would considered as shit hot with practically no wear. this was also just on the limit of being able to hone and re-ring.
ive seen people re-ring blocks that have had more wear in than what ive just done. and get away with it...for a bit anyway.
you used to be able to get ring sets with a 'ridge dodger' top ring. but the company that used to do them as most places got bought out, and stopped making them.
i think i could get some AE pistons for about £50 each. + obv rebore.
mahles are about £100each.
forged aftermarket from £450 up
or maybe even try autosprint pistons at £248 a set.
another way would be to get 0.5mm rings and gap them to suit, but that would take a while to do all 4 sets and cost quite abit and thats if people will say yes to doing it tbh
or you could have the block fitted with liners...but thats about £400 to have done too

hey, sorry ihavent been able to get on since last night.
All good suggestions here, very useful thanks!
I think im gonna go for the 87mm rebore and get new pistons. Those autosprint ones seem a good bet and that will get me the best part of 2.1 then too. Considering rings and clips are the thick of £100, they seem like a good bet! Dont know what make they will be though...
Cant thank everyone enough for all the help!  i thought it was gonna be massively expensive, but i think i may be able to get it sorted.
