    Yes it is the timing chain and yes it does require 2 chains, an upper and lower chain. I bought the timing chain kit and an extra chain $200. Labor will cost a lot of money. I was quoted as high as $460 but found a shop to do for $280.

    it is not an upper and lower it is the camshaft timing chain and a ballcance shaft chain. i just had a car with this problem a few weeks ago. it calls for about 5.2 hours on mitchell and was not that bad of a change. most likely you have a busted upper guide but dont be fooled into thinking you can chnge only that, if its broke you have a stretched chain.good luck
