Hi from Australia,

I have two 2001/2002 model Z22SE Verts (Holden badged Opel/Vauxhall), with about 120k and 170k on the clock.
I believe Vauxhall recalled them in the UK at some stage and had a <u>modified oil nozzle</u> fitted to overcome timing chain breakage problems. I am told this did not happen with Holden in Australia! Good on you Holden :rage:!!
So I would like to do a minimum fix to hopefully prevent the timing chain jumping a tooth or breaking and so wrecking the engine. Minimum because the cars are not worth a lot of money here ($3000 will get you one), and spending a couple of thousand dollars on that part of the engine is just not viable.

My question is, can I get away just with new upgraded chain tensioners (balance chain and timing chain); Or must do chains and guides as well?
I don't know where the oil nozzle/s is but that too if it is not part of the tensioner.
Part numbers please so I can see that what I buy on Ebay is the correct parts.

Of course one can keep going with sprockets and water pump etc etc but the $$$ add up.
Intend to do the work myself, using the great guide provided on this site.

Thanks

no cheep fix i'm afraid 🙁
z22se cars only sell for around £500-1000 in the uk unless it is a very clean low mileage example.
genuine gm chain kits can be found for around £400 for both chains. there are very cheep aftermarket kits around but they dont last.
new kits come with all the updated parts apart from the new oil pump which was also updated from the early engines with more flow at same pressure. (gm kept this one very quiet!)

As mentioned above - really not worth just fitting new timing and balance chain tensioners as this is false economy, both in cost of parts and labour, because to fit a new balance chain tensioner and oil jet you have to remove the timing/oil pump cover which is half the job. With the distances the cars have covered the chains are due for changing anyway.

Buy and fit new genuine GM chain kits and they will last ! 🙂

Timing Chain Kit - GM part #: 55570337 (includes Z20NET tensioner 12608580 and modified oil jet)
Balance Chain Kit - GM part #: 55563405

Thanks for replies folks. I had to ask in case there was a quick fix. o_O
Looks like $1000 odd bucks for chains etc if I do most of labour (without oil pump #93166701 I think, but EXPENSIVE).

Try getting kits form the usa. I used cloyes chain kits (which is OEM for the chain guides). It will be half the price of the GM kits easilty and quality is reasonable. Have done 45,000km with cloyes kits no issues so far........
