    Timing Chain Replacement

    Hey everyone. I have a 2005 Chevy Classic with a 2.2L ecotec. I was wondering if you have to remove the motor to replace the chain? Is it possible to remove part of the car body and go in from the side or underneath? Its really tight space.

    My 05 cavalier 2.2 ecotec timing chain was just done. I removed valve cover and side cover (remove fender liner) and go from there.

    Thank you. I had a the same engine in my Cavalier also until it met a telephone pole. The guide (or guard?) in between the two sprockets is all but missing. So far I just plan on replacing the chain, guide, and the tensioner. Should I go any further than that?

    ...... intake is blue, exhaust is red, crank is red. the red mark closest to the blue mark(intake) is the exhaust the one farther away from everything is crank. Line up crank at 5 o clock, exhaust at 10, and intake at 2 = Top Dead Center

    So I found my culprit. A broken guide on the slack side. The shoulder bolt snapped (the one through the access port) and the guide fell out in pieces. Does anyone happen to know what size bolts these are. I know its metric and it took a 10mm socket to remove. Any help is appreciated.
