There could be various reasons the chain let go early...possible theres an oiling problem there ( Lack of) or hard miles or a bad chain or even a bad tensioner from the factory but for most..shouldnt have any problems for the life of the eng....

Thanks for the help
The dealer told me they wanted 1,500$ for just the labor so i bought the parts for my self. I work on heavy trucks for a living, and have a good mechanical backround. So i would like to try and do this my self. Has anyone found a good manual i could use to help me thru this. I havent had much luck with You Tube.

This is a link for the 2.2l L61 but the timing chain part of the motor should be very similar if not the same. I also sent a PM on your behalf to Chevymgr to see if he can get the specific one for your motor.
From what I remember when doing waterpump campaigns on the first L61's it wasn't all that bad. It was mostly just having to raise and lower the engine to get to all the 10mm bolts holding the front cover on. For the most part it is very much like doing a timing belt. I do remember having to make sure to have the rod/pin in on the tensioner as you install. The waterpump is also driven by the chain so you might want to replace that too while you are in there. It bolts up to the front case from the backside below the exhaust mani but the gear is bolted to the shaft inside the front case. Again this was the first gen L61's when they still had power steering pumps and I have not looked that far into either of my newer L61's nor ever seen a LNF.

Remove the number 1 cylinder spark plug. Refer to Spark Plug Replacement (See: Spark Plug\Service and Repair).
Rotate the crankshaft in the engine rotational direction clockwise, until the number 1 piston is at top dead center (TDC) on the compression stroke.
Remove the camshaft cover. Refer to Camshaft Cover Replacement (See: Valve Cover\Service and Repair).
Remove the engine front cover. Refer to Engine Front Cover Replacement (See: Timing Cover\Service and Repair).
Remove the upper timing chain guide bolts and guide
Note: The timing chain tensioner must be removed to unload chain tension before the timing chain is removed. If it is not, the timing chain will become ****ed and it will be difficult to remove.

Thats $234 per hour !!!!
Dealer labor rates here are approx. $110 per hour.
If those figures are correct ... Chevrolet might be interested in why this High Rate also.
I don't think they would approve of ripping off Chevy Loyal Customers just because they didn't buy an extended warranty.

Something else to think about is replacing what other parts run off the timing chain. IDK about this particular motor, but the water pump probably runs off it too. Since you're already paying the labor - 6.4 hours does sound about right (Cav with 2.4 took that long) You might as well replace the other parts hooked up to the chain. At that mileage they may be on their way out too.
As others have stated $1500 is just too much. A second opinion would be recommended at the very least to get a more realistic price.
Good luck!!
