    Get # 1 up on the compression stroke as far as the piston will come up to the top of the engine block pull plug fill piston with something rigid but soft and then you will see which one you need which should be the second one.

1990 geo storm sohc is running rough. Parts that are new: cap, rotor, plugs wires,plugs, pickup coil, and the ignition module looks brand new. The coil is old, but is still sending spark through all t

the timing is 180 degrees out so ignore where no 1 lead should be and rewire the HT leads to the new position for no1 cylinder. The crank timing mark should be on 10 degrees advanced. Engines are timed off the crank position so forget the cam position.
Or you can start again. Remove no 1 plug and turn the engine over until you feel compression under your finger over the plug hole. Set the timing on the crank to 10 degrees before tdc. Position the distributor so that the point of the star is directly opposite the exciter coil in the distributor. The rotor button should now be facing no 1 cylinder plug lead adjust the HT leads so that they will fire in the 1342 firing order. Start the engine and with a timing light attached to no 1 plug lead adjust the timing mark to specifications by turning the body of the distributor.

How to set timing

Best way to set ignition timing is with a timing light, but if one is not available, then this method will work.. just takes a little longer...

Locate the ignition distrbutor, and look for a small L shaped bracked with one 5/16" cap screw that screws into the engine block, One end of the bracket rest on a flat surface of the engine block and the other end rest on a ring molded around the distributor housing and sits on the engine block.. loosen this cap screw about 3/4 turn, just enough to rotate the distributor by hand without the distributor moving freely...

Look at the damper/pulley on the front of the crankshaft and a small metal pointer fastened to the front of the engine block that points to the front surface of the pulley. Rotate the engine until you see a series of marks cut into the pulley surface.. Find the mark that is labeled 0 degrees and then find the mark to the left of it marked 3 degrees. Turn the engine until the pointer is matched to the 3 degree mark... Make sure the mark on the pulley that you select arives at the pointer before the 0 deg mark.. This allows the igintion to fire before the cylinder arrives at top dead center (TDC)...

With the timing marks aligned on the crankshaft pulley, rotate the distributor until the points open to maximum gap. Tighten the bolt to lock the distributor and crank the engine...

If the engine accelerates slowly without spark-knocking, then the timing is too slow and needs to be adjusted by moving the distributor one degree farther from TDC.. If the engine spark-knocks when acclerated, then the engine is timed too high, and the distributor needs to be set one deg towards the 0 timing mark...

With a little practice, you should get the timing correct...

Do not try to start the engine if you know the timing is set too high, as it will 'kick' back on the starter and can/will damage the starter and ring gear on the engine flywheel, which will require major repairs...

Im trying to time a 350 engine. it has two marks on it and im trying to time it at 34 degrees. One mark is 0 and one is 36 im pretty sure, but they are not labeled. So my question is which mark is which...

You paint or chalk the crank damper grouve first

Then you disconnect & plug the dist vacuum hose

Then you will see the grouve move up on the timing
tab as you turn the dist

Your setting the initial timing,not 34 on the tab

Don't forget the cam turns twice as fast as the crank
& thus the dist & then you add vacuum advance

Your setting the timing somewhere around 8 to 12 degrees
The correct setting should be on the radiator support

If the motor is in something different & you have an advance
timing light ,you can put 34 in the light & adjust the grouve
to O degrees on tab

'92 VW Golf 1.8L timing problems. Changed the belt but have no idea how to get the timing right

You should need the timing light if you didn't move the distributor. If everything is lined up to top dead center, it should start.Make sure the cams and crank pull are set to 0 or at their marked position. Then you can mark the crank pulley with nail polish or some paint at 0 degree and then turn your timing light on while the engine is running and adjust distributor to advance or ****** the ignition timing. Usually its around 8-10 degrees before top dead center. You could refer to the manual for the exact degree.

Can u help me with a timing setting on my 97 toyota camary le 2.2ll or some kind of mark to guide me on?

Are you looking for ignition timing or valve timing marks?
The ignition timing is set at 10 degrees BTC. the marks are at the front of the engine and the degrees are scaled onto a raised molding on the plastic timing belt cover. There is a line marked on the pulley. Paint with correcting fluid the 10 degree mark and the pulley mark. Correct timing is 10 degrees BTC.
Before setting, open the diagnostic connector in the engine compartment and using a short piece of electrical wire and bridge between "T" and 'E' If this is not done the timing will not be corrected.
If you've replaced the timing belt and you're looking for the timing marks, the mark for the crank shaft is a raised casting forming a small pointer for the crank shaft which aligns with a groove in the crank timing gear....When looking from above at the relevant section of the engine, it will appear on your right hand side just above the crankshaft timing gear.
The marks for the cams are holes drilled through each and these should be aligned with punch marks on the cylinder head. The best way of doing this job is by using a mirror and illuminating between the cam gears and the cylinder head.
Hope this helps

Want to know how to set motor up for top dead centre on number1 to replace distributor

There is a timing mark on the timing chain cover. Some have a little tube. The bottom center of the engine where the crank shaft is there is a harmonic balancer. The balancer has a line on it. Get the line right on the 0 degrees mark. This will be top dead center.

How to line crank and cam for timing belt on 1988 no crank marks

Hard to explain here... but I believe that car also has the balance shaft which needs to be timed as well. The camshaft has 2 lines which line up to the top of the head, and a "up" or "top" mark at the top.
Crank is set to 0 degrees.

How do i get my timing back on, on a 1997 Nissan Pathfinder?

Nissan Pathfinder engine timing is controlled by the Crank Shaft Angle Sensor, or in other words the distributor. which receives the signal from the ECU and the distributor receives its spark from the POWER TRANSISTOR, BASED ON THE CRANK ANGLE SENSOR **** POSITION. The distributor has 360 slits which measure the signal input at 180 degrees and 360 degrees.
The crank shaft pulley has timing marks in increments of 5 degress per mark. The correct timing for a 1988 V6 engine is 12 degrees BTDC (Before Top Dead Center) + or - 2 Degress (Strive for 12).
You can then attached the timing light to spark plug wire #1 and point the gun to the timing pointer. With each flash you should see the timing mark (Mark it with white out). If the timing mark does not line up you can loosen the distributor and move it so it lines up that is the damper mark with the pointer. EITHER RIGHT OR LEFT WHICHEVER WAY IS REQUIRED. It is imperative if you have manual tranny to ensure the engine is idling 850 rpms + or - 50, but strive for 850.
700 if Auto Tranny. + OR - 50
Don't forget to retighten the distributor.
