Hi all, Astra 2.2 Bertone Coupé, Z22SE. I have heard the cam chains and tensioners are hard to get hold of now, is this the case?
What sort of cost is replacement chains etc? 101k miles, engine still runs smooth, car does around 1000 miles a year at most, oil kept an eye on and topped up when needed, never has used a lot of oil.
The chain sets are still available, You can get them on ebay still.
You want to get genuine GM if possible . NeoBros is a seller that supplies the kits that you need , as well as other sellers, Just type in z22se timing chain kits in the search engine, I was looking myself a few weeks ago.
If you are getting a rattle on the chain side then possibly the chain is stretched or the tensioner is not functioning as it should.
