When turning the OPDA, like a distributor, there is only a small degree it can be turned either way before it shuts off so I cant be far off. The engine runs pretty smooth, but jostles when I am driving at about 3 grand.
On my '06 there is a groove cut into the harmonic balancer and an alignment "pointer". I think you need a 3/4" socket or boxed end wrench to turn the engine and removal of the serp belt makes it easier. If I remember correctly you turn clockwise facing the front of the engine. Once you get there you will be able to see how far off the housing alignment hole is from the tone wheel alignment hole.
