The timing chain broke on my 2002 Pontiac Grand Am 2.2L 4cyl engine. Since the car is 9 years old, has 140K miles, and is worth less than what a mechanic would charge me for the repair, I am replacing it myself. My prior mechanical work ranges form replacing a head gasket to replacing a light bulb in the dash. I have a working knowledge of mechanical things, but not a lot of experience with engines.
I bought the Haynes AND Chilton?s manuals to assist me in this repair. Both manuals list the procedure for removing the timing chain (and assorted things like the tensioner, etc), and installation. My question is this: If the timing chain is broken, and that?s the only thing that?s broken, do I need to take off all those other things, or can I just slip the new timing chain in place? For instance, do I need to remove and replace the camshaft sprockets?
