The marks on the pulley or flywheel will be TDC for top dead centre . correct ignition point is before TDC normally around 10 degrees and there will be a mark on the housing before the TDC point. You have effectively timed the spark in a retard situation and you need to get it advanced

The keyway and or the dot on the crank should be line at 12 oclock. You will see a point on the oil pump housing to go by. On the camshaft the pointer will be at 12 oclock also. Use the O on the camshaft to the top at mark. Be sure to look at the dist. roter to make sure that it is pointing at the #1 spark plug wire. I could get 180 out of time. If you do it right it should start up right away. then you can use a timing light to finish it.
Good Luck jerry1938@hotmail.com

SOURCE: need a picture or diagram of top dead center/86' honda prelude 2.

From what I see in my manual,

1.There is a Timing Pointer on the back of the engine. There is a White mark on the flywheel. The white mark must line up with the timing pointer, for Number 1 piston to be at Top Dead Center.

2.Facing the engine, looking at the camshaft sprocket. The sprocket has spokes. On one of those spokes is the word, "UP" in raised letters, or there is a small Dot. As you can see here, the spoke with the word UP goes -> Up.
(Same thing of course if it is a Dot, instead of UP)

On the back of the camshaft gear, (Sprocket), are marks. On the edges of the camshaft gear. These line up with the top edge of the cylinder head. The surface of the cylinder head, where the valve cover bolts down to.

I'm sorry, at present I do not have a website, that I could link you to for a diagram, or photo.

If you plan on doing more than light tuneup work, I highly recommend purchasing a manual for your car. We have for each of three vehicles a Haynes manual and it contains all the details on maintenance possible for the shade-tree mechanic. All are based on a complete rebuild.

Cam shaft


put the notch on crank pulley align with tdc (top dead center mark) on timing cover

Remove valve cover, firing order for a 4 cylinder engine 1342, piston 1 and 4 are up in same time,rocker arm on cylinder 1 intake and exhaust must have play, while on cylinder 4 must be in overlap both valves starting to open (partly depress),if no timing mark inser a screwdriver throught sparkplug opening turn gently to get the piston at tdc if so valve timing is ok without checking any mark,if you remove the cover you will see the mark at the right place

1 and 4, 3 and 2 are companion piston, you could do the same with 6 or 8 cylinders, you must know firing order

Engine valve timing


To find TDC remove number 1 plug and place the crank pulley timing mark on tdc . Using a piece of soft wire etc move the crank back and forth and determine when the piston is not moving That will be TDC no 1 piston It should line up with the TDC and mark on the pulley.

Overbored a cl175 50 thousands .cant get it timed.acts like it is out 180.


You're wrong. It should not fire when the exhaust valve is open-that is the exhaust stroke. As the piston moves down after the exhaust stroke, the intake valve opens and the air-fuel mixture is pulled into the cylinder. Then piston travels up, compressing the mixture( both valves are closed, now), and at the top of this stroke the ignition fires, driving the piston down.
Sounds like your timing is a bit too soon, if it's firing when the intake is open. Try retarding the time just a bit.
If that doesn't work, find tdc of the compression stroke of number one cylinder: pull the sparkplug out and turn the crank around by hand (with a socket on the crank pulley) with your finger over the plug hole. As the crank comes around to the zero mark (TDC), you will feel pressure bui;ld up on your finger if you are on the compression stroke. If you are on the exhaust stroke there will not be pressure buildup as the piston approaches TDC. Once you have number one cylinder at TDC of the compression stroke, the rotor will be pointing to the number one plug wire tower on the distributor cap. If the dist. is off 180, rotor will be pointing opposite of number one.

How to change a timing belt


You may follow these steps:

1. Remove any shrouding in the wheel so that you can access the lower timing belt pulley and the crankshaft snout.

2. Locate the timing marks on the flywheel and cam, then you set them both to TDC. The flywheel pulley TDC mark is accessible through a hole in the bellhousing. The camshaft TDC is easy to locate, especially if you added some marks.

3. Support the engine with something like skyhook if you want to remove the rightside motor mount. Most belts are installed with a mount in the center, making them problematic when changing. You can now remove the motor mount temporarily.

4. Freeing up the belt tensioner pulley can release any belt tension.

5. Slip through the new belt into place and make sure that you are not disturbing the cam or crank pulleys, or else the engine will be out of time if changes and adjustments are made. Then check by slowly rotating the crank to two full turns with a socket on the crank snout.

Doing Top Dead Center(TDC) before T-belt


It is important that you turn the engine in the correct direction. To achieve TDC firing stroke remove spark plugs insert a plasic straw into the number one spark plug hole and proceed to turn the engine over observe the straw keep turn ing the motor until the straw travels upward when it stops moving up stop turning, you will know you are at tdc by looking at the timing marks down on the crankshaft pulley the notch on the pulley should line up exactly to the number zero on the timing plate at the front lower part of the motor very close to the crankshaft pulley turn the motor over again and again until you line up the notch on pulley with the number zero you may need to clean the numbers off on the timing plate or front cover.

1991 toyota p/u timings not right. If crack is at


If the crank is lined up to the mark, it is at TDC, meaning cylinder number 1 piston is at TDC.

Both cam pulleys should have marks, they just look a little different.
Here are the diagrams to help out.

Still need advice


Turn crank so that timing mark on front pulley is at 0 degrees.
Remove the timing cover and you should see a mark for the cam to line up with.
You want the cam lobes on No.1 cylinder to be pointing away from the followers wether they be rockers above cam or buckets below. This will be the compression stroke.
Once the cam timing is set you can recheck the distributor. It should point to No.1.

Fly wheel problem on a jeep


if its a 4JX1 diesel, yes it goes in 1 spot yet it can be bolted up in every location
put crank pulley timing mark to TDC can also check by removing cam belt top cover and check timing mark aligned up with mark at 12 O clock then flywheel has small notch in edge that must go at 6 O clock (facing down) look closely it is hard to see due to flywheel sunk into back of block.
