My gf's car started having a rough idle and at start up a pretty crazy slapping sound coming from the valve cover. After some research It was determined that its most likely a timing chain issue because of the chain tensioner.
I pulled the valve cover off and found the chain pretty loose, no problem. But then I notice the the red chain link is way off target
As you can see in the pics the green link is off by 1, and the red is off by 2.
I'm hoping this this is just a matter of removing the tensioner, moving the exhaust cam back to the 10o'clock poistion and the green one to the 2o'clock position then installing a new tensioner.
