I am replacing a timing chain on a 2.2 liter Sonoma 2wd. The timing mark on the crankshaft sprocket looks like a little drill mark. I think this is supposed to line up to the tab on the tensioner. The mark on the cam sprocket is the one Im not clear on. What does the mark look like and does it line up on the top tab on the tensioner? The Haynes is not very clear on this. Wish I had a good pic. This is something that is already apart and I was told when these marks were lined up that the engine would not start but would backfire through the TB. Im wondering if the timing chain setup is wrong or if a valve got bent when it jumped time. Any help is much appreciated.
