my 2.2 has a bit of a rattle to it..... Im almost 100% sure its either the chain or the tensioner........ it has 235 kms on it, would this be normal? or what?
would I be better to wait and do the 2.4 swap? or just do the timing chain....
I would buy a GM Tensioner (I have had bad exp with aftermarket ones) and a new chain. You may need new sprockets but I doubt it.
I did a write up on how to change it like a year ago. I'm sure if you search the archives you can find it.
