3 timing chains in less then a year
My brother has an 02 cavalier OHV and we have replaced the timing chain 3 times since june of 2011. I changed it the first time and a shop has done it the other 2 times. Anyone know what might be causing this?

All the gear have been replaced twice. I don't know about the alignment there is no warranty because it is not defective parts. The shop said they could find the casue but it would take $$$$$$ which I don't have. Thanks

When you did the repair did you make sure the alignment was proper?? Do you have a factory service manual for instructions?? I have not done the repair but from what I read alignment is very critical. Have you talked with a dealership about problem? Hopefully someone else with experience of the repair will comment.

the last time I had it done was at the dealer cause the shop I used went out of business. The dealer said they would have to trouble shoot until they found the problem

Re: 3 timing chains in less then a year
Which engine is it, 2.2 or 2.4??? Any odd noises before this happens?? Have you done a compression test once new timing chain is installed??? From what i gather this is a interference engine. Do the valves move freely???

Re: 3 timing chains in less then a year
Is this the Ecotec engine? I believe this is an interference engine....hard to believe the valves aren't bent when this happens....
I believe there was a TSB about this problem, stating that the cam and crank gears had to be replaced, along with a new chain and tensioner, and ALSO the oil nozzle had to be replaced.....I believe it has a larger opening....were ALL these parts replaced, including the nozzle?

it is a 2.2 OHV not the Ecotec. all gears and tensioner was replaced with the chain. I was told that this was a noninterference engine. I will check with the dealer. the oil nozze was not replaced that I am aware of
