Following Manual

This eliminates the need for velocity and vacuum to pull the mixture into the chamber. It’s essentially thrown into the chamber. So to begin with timing a camshaft, the motor needs to be set at top dead center of the compression stroke. If you are unsure what this means, remove the valve cover on the driver side, rotate the crank pulley with a 32 mm socket, until you see the intake valve, which is the second valve spring, begin to compress. When I say compress, this means the valve spring is opening the valve. As the valve spring begins to close, the piston will be approaching the top of its travel. The crank shaft pulley/harmonic balancer, will have a mark to indicate top dead center on the timing cover. This Mark will align with the TDC mark on the timing cover just after the intake valve spring closes. Next, using a half inch wrench, remove the distributor and set to the side. With a flashlight, look down inside at the oil pump driveshaft. It will have a slot in the center of the gear. This slot should be pointing towards the number one intake manifold bolt hole. It will almost be front to back, but it will be skewed slightly toward the AC unit. If it is not, using a long flat blade screwdriver, rotate the oil pump driveshaft clockwise until the slot lines up with the number one intake manifold bolt hole. Reinstall the distributor and snug the half inch bolt down. The rotor should be pointing towards the number one cylinder mark on the distributor plate. Reinstall the distributor cap and try to fire the motor over. If the engine idles correctly, then take the vehicle for a test drive. If you do not have any major detonation from pre-ignition, in the last thing to do is to set the sync between the crank shaft sensor and the camshafts sensor. This is done by using a scan tool such as the dealership DRBIII, Snap-0n scanners or that any other top of the line scanner. Setting the sync using an ohm-meter has never proved to be accurate and can be off as much as negative six.
