My mechanic told me it is a 1.5k job to replace the chains but I'm sure it could be done cheaper.
His experience supported what I had read about the stretched timing chains being an early VE problem. He said he rarely sees the timing chain problem with the VZ. Premature cooling system thermostat failure was common in early VZ Alloytecs.
In any case he told me not to worry about it as if there is a problem with the chains stretching the ECU will throw up an engine warning and the fault code will indicate there is a problem with the camshaft timing. Worst case apparently is the ECU will go into limp home mode.
Probably the quality of the chains is the problem. Made in China???????????
