Check and adjust ignition timing

1. Locate the service check connector and, if applicable, remove the cap. On 1988-91 Preludes, the cap is yellow and the connector is located next to the vacuum control box in the engine compartment. On 1992-95 Preludes, the service connector is located under the middle of the dash. On 1990-93 Accords, the connector is blue and is located behind the right front kick panel, under the dashboard. On 1994-95 Accords, the service connector is located behind the glove box. Use a jumper wire to connect the two terminals of the service connector.
   

1. Following the manufacturers instructions, connect a timing light to the engine. The positive and negative leads connect to their corresponding battery terminals and the spark plug lead to No. 1 spark plug wire.
2. Make sure that all wires are clear of the cooling fan and hot exhaust manifolds.
3. Set the parking brake and block the front wheels. Start the engine. Check that the idle speed is set to specifications.
4. Point the timing light at the timing marks. On all models except 1994-95 Accords, the marks are on the flywheel. On the 1994-95 Accords, the timing marks are on the crankshaft pulley. When the engine is idling, the red mark must align with the pointer. Some timing marks are indicated by 3 lines; the center one must be aligned with the pointer.

1. If necessary to adjust the timing, loosen the distributor hold-down bolt(s) and/or nut and slowly rotate the distributor in the required direction while observing the timing marks.
2. To complete the adjustment operation, tighten the hold-down bolt, taking care not to disturb the adjustment.
3. Switch the engine OFF . Reinstall the rubber plug in the timing window and remove the timing light. Remove the jumper wire.

Disconnect the negative battery terminal. Using a ½-inch-drive ratchet and the 19 mm socket, turn the center bolt on the crankshaft so that number-one cylinder piston is at top dead center (TDC). You will know you ware at TDC when the mark on the crank is in alignment with the arrow on the timing cover.

Disconnect the cruise control connector and remove the cruise control actuator. Loosen the upper mounting bolt with the 14 mm socket. Use a 12 mm socket to loosen the lower nut then use a 10 mm socket to loosen the adjuster from the power steering pump and remove the belt.

Loosen the upper air conditioner mounting bolt using the 14 mm socket. Use the 12 mm socket to loosen the lower nut and adjusting bolt on the alternator and remove the alternator/AC belt. Remove the valve cover using a 10 mm socket.

Place the jack behind the left front wheel where the arrow is located indicating the jack location, and raise the vehicle. Put the jack stand under the subframe behind the jack, then lower the jack. Remove the left front wheel for easy access to the crank pulley. Using a block of wood atop the jack, place the jack under the oil pan and lift with slight pressure to hold the engine in place. Remove the side engine mount using a 17 mm deep socket.

Take off the dipstick, pipe tube and upper timing cover using a 10 mm socket.
Then remove the timing belt adjuster rubber seal without loosening the adjuster nut. Take off the crankshaft pulley bolt. Use the chain wrench to hold the the crankshaft pulley while turning the crankshaft pulley bolt with a 19 mm socket. Use the 10 mm wrench and 10 mm socket to remove the bolts on the lower cover. Remove the lower cover and mark the location of the cam, crank and balancer shaft with Liquid Paper. Remove the balancer shaft belt and timing belt. Install the timing belt and the balancer shaft belt in the reverse order of removing them. During Installation of the crank pulley, coat the threads of the crank pulley bolt with engine oil and tighten it to 159 foot-pounds. Finally, adjust the tension of the power steering and alternator belts as well.

YOUR DISTRIBUTOR HAS 3 BOLTS HOLDING IT IN PLACE.LOOK AT THE DISTRIBUTOR AGAIN VERY CLOSELY.YOU HAVE 3 BOLTS HOLDING IT..

the distributor has three bolts holding it tight against the engine head you will have to loosen them using a 12 millimeter wrench and then you can turn the distributor to advance or ****** the timing.

Distributorless Ignition is not adjustable However the Distributor Ignition System is
1 Place Transmission in Park on Manual (Neutral and set Park Brake
2 Ensure all accessories are off AC ,Heater, Radio, ETC...
3Connect an inductive timming light and Tach to the Engine according to manufactures instructions
4 disconnect the single wire inline spout connector or the shorting bar from the double wire spout connector( should be located near hood hinge on fenderwell drivers side small Gray plug with pc of Tape around it ) or near distributor
5 using a pc of yellow chalk laying flat onto the Crankshaft harmonic balancer and marking the entire timing marks area this will make it easier to see the correct timing marks
6 Start engine and bring to normal operating temp.
7 Check Idle speed and adjust if needed this should be non adjustable on your vehicle
8 Check initial timing by aiming the timing light at the marks and pointer.see emissions label under hood for exact timing Specs.
9 if the marks don't line up shut down engine
10 loosen the hold-down bolt on the distributor base but not so much that the distributor turns when assistant restarts the engine
11 restart engine
12 have assistant aim timing light at marks and pointer
13 while holding the distributor Base Shaft with the proper sized wrench at the base or insulated channelocks loosen the hold down bolt and advance or ****** the distributor until the correct timing marks line up.hold in that position while assistant shuts engine off
(NOTE) when retightening the distributor bolt it can have the tendancy to turn the distributor
14 retighten the distributor bolt while holding the shaft firmly to prevent spinning
15have assistant restart engine
16 Verify that the timing marks still line up with pointer if non alignment , readjust using steps 9 thru14 again
17 once it is set correctly and bolt is tight on distributor base shut down engine. Reconnect in-line Spout Connector or reinstall inline spout shorting bar and assure that timing is advancing beyond initial settings by starting the engine and aiming at the timing marks when engine is slightly reved the timing should advance slightly 2-4 degrees maybe more depending on mileage
18 if timing can't be achieved because distriburor was removed you must
1 unhook coil wire
2 remove the #1 Sparkplug verify that the #1 piston is at the top of the compression stroke (must be on top compression stroke) if it isnt have assistant crank engine slightly to get close with coil wire unplugged. DO NOT turn the crankshaft backwards at any time to get piston into position 3 once piston is in position remove the battery cables, remove the distributor cap with wires intact and verify that the rotor cap is at center of the #1 point in the distributor cap if it isn't
4 loosen & remove the distributor bolt
5 lift the distributor only slightly enough to disengage the gear on the shaft from the camshaft gear (NOTE) when letting it back down into the engine it will spin the rotor off of the #1 position so it must be turned far enough to compensate for this turning when it is reinstalled
6 seat the distributor shaft in the hole and reinstall the retainer bolt and tighten then use the steps above to fine tune the timing

Locate the crankshaft pulley at the front of the engine and remove any grease or dirt to expose the timing marks. Turn off any accessories such as the radio, climate controls and lights.

Step 2 Start the engine and allow it to reach normal operating temperature. The cooling fan will cycle on and off signifying it has reached the correct temperature. Shut the engine off.

Step 3 Connect the timing light to the battery if necessary and to the number one ignition wire located at the far end of engine on the driver's side. Restart the car and allow it to idle for 2 minutes.

Step 4 Point the timing light at the crankshaft pulley and determine the amount of adjustment needed. Loosen the hold down bolts on the distributor and rotate it slowly until the timing mark matches the middle line on the timing light.

Step 5 Tighten the distributor hold down bolts and recheck the timing to ensure it didn't move. Turn the engine off and remove the timing light. Reconnect the number one ignition wire.

At the base of the distributor there is a metal bracket with a bolt holding the bracket to the intake manifold. This is the distributor hold down bracket and you will need to loosen the bolt a few turns. A timing light is needed to find the correct timing of the engine, so connect one to the car in proper order. With the clamp loose and the timing light on, start the car and point the timing light at the harmonic balancer where the timing gauge is located on the timing belt cover. The light will show you where the timing is and so adjust the distributor (clockwise or counter-clockwise) until the desired setting is achieved. When the timing is set, turn off the car and tighten up the hold down bolt, be careful not to turn the distributor, and this is how to set the timing.
