Need to know how the timing marks are set on a 91 honda accord

Check with your local Auto Recycling Center or otherwise known as Auto Salvage Yard.

you need back to the timing belt and re_check the marks for the timing belt this are on the camnshaft and cranck shaft put on the EXACT position .I think is all what you need if is not explain with more details tnk.

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.

You need a timing light.
Hook up the timing light (follow it's instructions)
Warm the car, find the timing marks using the light.
Loosen the distributor and bump it forward or back, whichever corrects your timing.
The honda has three timing marks. I found it useful to dab some white out on the marks to make them easy to see.

u must hav a haynes manual--dont start it if its not correct cause u cud warp the valves and then ud be changin motors

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

If you have not removed any of the pulleys that the belt goes around or you know they are in the correct positions on their shafts, the timing pointer must be aligned with the white mark on the flywheel(at the view port); the cam pulley must be set so that small dot or the word UP is vertical and the marks on the edges of the pulley are aligned with the surface of the head(you might have to use a straight edge to check).
Hope this helps you.

All you need is to adjust the valve tappet clearance back to the original specification. It is a time consuming effort and require passion to do it. You need to remove the top engine cover, set timing belt to top dead centre then adjust intake & exhaust valve clearance one by one. Rotare the cranckshaft 180 degree and repeat the valve clearance,. I would suggest to leave it to the expert.

• first of all you are probably going to need a torque wrench for the crank shaft pulley bolt it has 225lbs.of torque or more.I just did one on my 1991 honda accord dx .you have to take off a/c belt ,alternator etc. on the crank pulley.(I took it to a shop and they heated the 3/4 in. bolt and used torque wrench. I broke a half inch breaker bar trying to get it offf) next use puller to take off crankshaft pulley.support motor and remove motor mount bracket. take off upper and lower timing belt covers.take off timing belt and other belt using the tensioners.take off and replace water pump CHECK ALL TIMING MARKS with #1 piston@TDC. There are about 6.

there is timing marks on the camshaft where you line it up it can be difficult
