stripped the zvh down 2 day 2 find number 1 has a bent rod & number 4 looks like this!



has accralite 12076 writted on bottom of crown also 1156xc 86

been on the accralite website & cant find any matching numbers 2 this & have emailed them.

any1 know if this is standard or not?

dont know if its worth me rebuilding this lump or just 2 buy another 1

 

I would say, if your piston looks like that, the bore cant be much good either.

so a over size bore and 4 new over sized piston would be needed.

As for the number on there, no idea TBH, have a look on burtons website, they sell them pistons on there.

 

bore actually doesnt look that bad, might see about buying 1 new piston & geting all bores homed out & oversize rings fitted

 

you can only take a bore out so far before they are out of tolerance for the pistons.

And tbh...........while you've got your wallet out, you want to be considering spending some cash where its really needed, thats some serious lean running you've been having.

Pointless buying a new piston only to go and melt it again, and if you fancy your chances this time round you will be sorely dissapointed.
