The basics of setting the camshaft synchroniser are as follows:
1) Set the engine #1 cylinder to TDC on the firing stroke, after setting the transmission in Neutral.
2) Position the synchroniser alignment tool onto the head of the synchroniser body (the camshaft sensor needs to be removed). The worm gear will need to be rotated to allow the tool to be installed.
3) Engage the synchroniser body worm gear with the camshaft IN THE CORRECT orientation. This is most important otherwise the fuel injection timing could be compromised. (See Handbook for correct angle or see link below) NOTE: setting angle for 4L is different than 3L. If the angle of the synchroniser is not correct the check engine light (CEL) may become illuminated. The synchroniser will continue to rotate as you push it down into the engine block, it will then be at a different angle. The angle of engagment is what the diagram linked below is showing, i.E. The angle before the synchroniser is seated to the block.
4) Tighten the hold down clamp making sure the crank/camshaft does not move at any time. Recheck the alignment angle !
5) Remove alignment tool & refit camshaft sensor. Do not allow the engine to rotate until the alignment tool is removed!
