In the process of changing headgasket on 95 E320. In order to achieve TDC at the crank and with the two dowels, we had to turn the intake VVT to make everything line up. Which way do you turn to advance and which way to retard? Basically, the engine is at TDC now. Will I need to turn the adjuster the other way to retard upon re-assembling the engine or is it already retarded at TDC?

On a side note, how does the VVT work? (How does it adjust +/- 20 degrees)? I see two wires going to the cover of the VVT, that is it.

Need this quick, thanks
