If you still need the info, here it is:

Align the crankshaft as pictured below.
Then rotate the crankshaft clockwise 57 to 63 degrees.
Torque the rocker arm nuts to 18 foot pounds.

When the marks are lined up as they are in the image above, the mark at the 2:00 position indicates #1 piston is at TDC, (Top Dead Center).** The mark at the 4:00 position is 90 degrees BTDC, (Before Top Dead Center) for #1 cylinder.

On a V6 engine, one cylinder fires every 120 degrees of crankshaft rotation. Not sure why they put 2 marks on it

**Depending on the position of the camshaft, it could be the end of the compression stroke, or the end of the exhaust stroke.

If the distributor is off one or more teeth when the engine is running, DTC P1345 will set in memory and if the check engine light works, it will come on. If it is meshed correctly, camshaft retard is within ~27 degrees, (desired spec is zero degrees with a tolerance of + or - 2 degrees).
