Hey guys, I dont know if its been discussed over here as much as over on PO but a lot of ludes are having some hesitation problems. Well, in the quest to find what was causing my hesitation, I wanted to check my timing today. I popped the valve cover over, set #1 to TDC, pulled the plug on the tranny so I could see the flywheel. Here is where I am unsure....since #1 is at TDC, should the TDC mark on the flywheel be directly across from the "arrow" that you use when doing ignition timing? There are four marks on the flywheel, TDC, +12, +15, and +18 I think. My #1 piston is at TDC, and the "arrow" is pointing nowhere close to the TDC mark on the flywheel. The TDC mark is about an inch above the arrow, and the other marks are about 3/4 inch below the arrow. Above and below refers to if you are looking in the hole.

Can someone help me out on this? Shouldnt the TDC mark on the flywheel line up with the arrow? I did go from 3rd to 2nd at the track before all this happened. I had a problem with my linkage not being secured, thats why. Does it sound like I skipped some teeth on the timing belt? If that is the case, what is the best way to get it back to TDC? Also, did I skip some teeth on my crank, or is it coincidence that I just skipped the same amount of teeth on the cams because the gears are both lined up the same. Thanks for any help guys!!!

 

make sure the Arrows are pointing up, and the line is running across itself in the center.

 

There are no up arrows. I know not what you speak of. lol

Are you talking lines on the flywheel? No lines on my flywheel, its a JUN, but that doesnt matter.

All I need to know is if the TDC line should be right across from the metal arrow looking think built into the tranny. You know the "arrow" you use when using a timing light to set your timing? That is what I am calling the arrow.

 

How exact does it have to be guys? The arrow have to point directly at the TDC mark?

 

Sheesh, nobody knows? This is Honda-TECH.

 

If you had a stock flywheel, the arrow will be either directly across from the red 15 BTDC mark or within +/- 2 deg. range, so in between 13 and 17 BTDC (the other 2 red marks). If you had a timing gun that you can advance (has the dial **** on the back), then when you advance the **** to 15 deg, the white mark should be directly across the arrow.

I see that you have a JUN flywheel. Does it have a TDC mark on it? If so, then you will need the timing gun with an advance **** like how I described above.

NM....I got it.

Thanks.

 

And yes, the JUN has a TDC mark, the 15 degree mark, and the +/- 2 degree marks.

 

I dont want to start another thread so I'll post in here... How do I check my timing using a timing light. Its an H23 engine I'm not sure where to point the light. Also what is stock timing set at, I dont believe its 0deg is it?

 

I talked to my brother (95' GSR) he said that I have to jump a connector with a paper clip so I trip the check engine light before I attempt on adjusting the timing, is this true? I thought you only had to do this for OBD II cars?

 

Do it for any car. It blindfolds the ecu while you adjust your ignition timing.

 

Well you will clamp the clamp on the #1 spark plug wire. Then you will hook up your wires to the battery. Then you will get under your dash and find the blue plug and put a jumper wire between the 2 holes. Then there is a little rubber plug thing on your block right beside where the H23A1 is stamped. Remove the plug. Start your car and let it warm up. Until the idle is down to 700-800 rpm. I think the rule of thumb is until the fan comes on. Then depending on how your light is set up... you just point it in the hole and line up the little white line. If it needs adjusting you just have to loosen the 3 bolts on the distributor just enough that you can turn it. Turn it towards the front of the car to retard it and towards the back to advance it. Get it where you want it... tighten your bolts... and you're done. Good Luck

 

Thanks a lot of the info... can somone tell me where the blue plug might be, drivers side or passenger side?

 

4gen is it behind the rear of the center console, back by the gas pedal.

 

The helm manual says to jump the ecu then set ignition timing to 14 deg btdc. If you skipped teeth on the cam gears, the car would run poorly. One other thing I've read about is to check the phasing of the rotor inside the distributor. The ECU has some control over the ignition timing, and if it is advanced/retarded to the point that the rotor doesn't line up with the post inside the distributor cap, then you can have hesitation or misfiring. Just something to think about...
