Align the gold or yellow links with each timing mark located on the camshaft timing gear and sprocket, then install the chain.

Remove any oil from the contact surface.
Install the chain cover within 3 minutes of applying seal packing.
Do not add engine oil for at least 2 hours after installing the chain c
To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you'll advance the timing by rotating the distributor counterclockwise, and vice versa.
Step 1
Mark the spark plug wires for the cylinder number using a short piece of masking tape on each wire. Remove all the spark plugs using the spark plug wrench. The engine will be easier to turn by hand with the spark plugs removed and it's a good time to replace them if required. Remove the valve cover from over the number one cylinder. On a V-block engine this is normally the valve cover on the driver's side. On in-line engines the number one cylinder is the one closest to the front of the car. Check your vehicle's specifications to be sure which cylinder is number one.
Step 2
Rotate the engine clockwise and observe the valves on the number one cylinder. When both valves are in the up position, insert a screwdriver into the number one cylinder through the spark plug hole. Rotate the engine very slowly back and forth until the screwdriver is at the maximum height. This indicates the number one cylinder is at Top Dead Center or "TDC" on the compression stroke.
Step 3
Locate the number one spark plug wire on distributor cap and make a tic-mark of this position with a marker pen on the distributor housing. Remove the distributor cap and observe the position of the rotor.
Step 4
Loosen the distributor hold down bolt and turn distributor until the rotor is lined up with the mark you made in Step 3. Your timing is now set to zero degrees of mechanical timing.
Step 5
Replace the valve cover using a new gasket. Replace the spark plugs and spark plug wires using the marks from Step 1. You may want to mark the harmonic balancer with a zero point referenced to a fixed point on the engine. A fixed point could be a bolt head or accessory bracket that does not move when the engine is running. Later on this mark can be used as an indicator for stroboscopic timing.
Step 6
Connect a vacuum gauge to a manifold vacuum source. Most engines will have a port at the base of the carburetor or throttle body where a gauge can be connected. Start the engine and observe the vacuum gauge reading.
Step 7
Turn the distributor until the maximum vacuum gauge reading is noted. Back off one inch of vacuum from the maximum reading. Tighten the distributor hold down bolt. Normal readings average from 14 to 21 inches of vacuum depending on the condition of the engine.
Test drive the vehicle and listen for pinging noises. Repeat Steps 5 and 6 if excessive pinging is heard, or if there is a significant loss of power. The timing is correct when the vehicle operates at maximum power without the engine hard starting, backfiring, or pinging on acceleration.
