Z22SE Timing Chain
The timing chains on the early z22se's were fine, the problem was with the oil jet that supplies the chain with oil would become clogged and stop working efficiently. This inefficiency causes the chain to heat up quicker and stretch, eventually snapping and potentially causing a lot of damage to the internals of your engine block. Replacing the chain is actually a fairly easy job to do, as long as you have patience, common sense and use the TIS Manual (here) you should be able to change it in a day.
There are a couple of things you can do to see if you have the later oil jets fitted;
1. Check the year of
manufacture, anything before 2003 probably has the early oil jet
The chains have been known to snap on engines as young as 19,000 miles, so if you hear a ticking get it looked at!
