[QUOTE=alfaitalia;17515989 A cam chain should last the life of the engine. But I when it snaps ...I guess it DID last the life of the engine!! [/QUOTE]
Kind of like in the early 2000's with ZF's and their 'sealed for life' transmissions.
Car manufacturers might as well say the engine oil is 'sealed for life' and when the car comes to a grinding halt and seizes up, well there is their life.
Usually cam-chains are ok. It's just when they are rattle a lot at start up, and beyond start-up that you need to start factoring in a replacement. If you have frequent oil changes it will increase chain and general engine life. It Depends how much you use the car as well. If it is only once a week for 100 kms you could probably get by with a one year oil change. If you use it every day, but only 10kms a day 6 months could be beneficial.
The 3.2 is based off a GM unit that was made in Australia. I had a quick look online and some of the cars (Holden commodores) running that engine for sale in my country have had cam-chain replacements from about 150,000kms to 190,000kms.
