    Bottom end gone

    Done a compression check today because my ZLET through up a fault code of a misfire on cylinder 4 and found out that the compression was extremely low (6-7 bar).

    I'm starting the rebuild soon but just wanted to know if the block usually get badly scored on this engine therefore needing a re-bore with oversized pistons?

    If it doesn't it ill save me a lot of money just replacing the rings.

    Thanks, any input is appreciated

    you running any map by any chance? read on thorney other day about number 4 failing due to an un named company hand held re-map tool.....

    VXR block with accralites and arrow rods is the way forward
    No longer GSi power
    Dirty Derv Decked Vec is the way forward for me!

    It does have a map actually, but I dont see how that could sha9 only 1 cylinder.

    Just going to rebuild the ZLET as its cheap to do and its as strong as the ZLEH.

    Does anyone know if Vauxhall recommend changing the sump gasket or can it be reused with sealant?

    I know of at least 2 other people who've had the same problem with the re-maps from an un-nmed company's hand-held tool...oh, and both have been with cylinder 4.

    I found what I was looking for on the website, interesting read but looking at their tuning packages for the Corsa I see no mention of upgraded injectors.
