The cam chain issue is a bit worrying but once its been done there's nothing to worry about for another 100,000 miles. There's a few chaps on here, Daz and Benny who will gladly do your chain kit replacement if you needed it doing for a fraction of the £600 that Vauxhall charge.
My car has only done about 5.5k in nearly 2 years and i've changed the oil 4 times!!
:shock:
The z22se engine is a good solid reliable engine. 10,000k oil changes are a bit of a long stretch in my book but each to their own.
