Z22SE BOTTOM END.CONROD FAILURE

DaytonaBenz

HI GUY'S NEW TO FORUM,
I HAVE A ASTRA COUPE 2.2 AND THOUGHT IT HAD A TIMING CHAIN PROBLEM,HAD THE ENGINE TAKEN APART AND ITS SMASHED A CONROD TO PIECES,NICE LITTLE HOLE I THE FRONT OF THE BLOCK TOO.
FULL ENGINES ARE QUITE EXPENSIVE SO I BEEN OFFERED A 2.2 VECCY CDX WITH BENT VALVES,ARE THE BOTTOM ENDS THE SAME AS I WANT TO REBUILD THE ENGINE WITH MY HEAD.
WILL CHECK MY HEAD FOR DAMAGE BUT IT LOOKS LIKE MY VALVES ARE FINE PROB CHANGE 2 VALVES MAX,ANY OTHER ADVICE WELCOME

THANX BENZ

Yes they are the same.

As I just posted in another post with a chap with the same issue make sure you pop a set of rings in whilst shes out on the bench.

make sure the pistons are not damaged by the valves, the rings can bind and thus the engine will burn oil

I've just rebuilt an engine which suffered conrod failure with a block from a snapped timing chain engine, so have a few parts if you need any

The speedo is electronic? Check wiring connections. Maybe something not connected? Possible fuse?
