sorry I missed this thread :oops:
secondhand engines are costing upto £1000 now, they have 50,000 miles on them too and still need a new timing chain kit + oil change before fitting
so my advice would be;
a - if you wish to keep your z22se car for a while then buy a vauxhall recon engine
b - have your engine repaired, but get the piston rings checked for free movement
3 - depending on the value of the car it may be best to sell it as a non runner / break it for spares :shock: cry..
