First things first, Find TDC #1 piston, front passenger side, Firing order 1 8 4 3 6 5 7 2, Passenger side bank 1 3 5 7 , drivers side bank 2 4 6 8 .
Once you have established, for certain you are at TDC #1 piston, both valves closed, the pointer on the timing cover should be pointing at TDC marked on the Damper pulley.
Now with TDC established, note that when you lift the dissy out of the block the rotor button will rotate a small amount, slide it up and down and note how far it is moving, you will need this info later. Now find #1 spark plug lead on the dissy cap, fit the cap to the dissy and mark the exact centre of #1 on the dissy body. Now turn the rotor button in the opposite direction of normal rotation the small amount you noted when lifting the dissy out of the block. When you slip the dissy back into the block and engage the cam gear the rotor button should turn and line up perfectly with the #1 mark on the dissy body, if it doesn't line up, lift the dissy up enough to clear the cam gear and turn in the direction required to line up the rotor button with the mark on the dissy.
Once #1 has been established fit the next plug lead #8 next to #1 on the side of rotation and fit to #8 spark plug, repeat until all are fitted, good luck, Regards Frank.
