Need d15b8 cx engine expert finding tdc mark 93cx crank pulley frustrating long.
Ok this is the situation. The timing had broken on my 93cx while on the freeway. Took the car to a mechanic and he had changed the timing belt. I was about 2 hours away from my house with no tools and had no choice so I paid for a mechanic to do my timing belt.
So I had back to the house and notice the engine making some pinging noise while driving. I put the cam to tdc and noticed the mechanic used the white notch which is between two notches on the crank pulley as the tdc mark. I know usually the hayes or helms say to use the white mark as the TDC mark, but this white mark I believe is the Before Top dead center marks for timing. After the three marks which looks like this III there are two more marks which look like this II. I took out the spark plug in cylinder one and placed a long socket extension into the cylinder. While the extension was resting against the piston I spun the crank shaft counterclockwise and the extension was still climbing up as the pointer past the white mark which was between two marks. The piston stoped around the area reaching TDC near the two marks. As I recall in the past usually the TDC mark on the crank pulley is by itself. There are a total of five marks on the pulley, III II <-----like that. I took the belt off and put the cam at TDC. I proceeded to try to align the bottom crank pulley with one of the two II marks. One tooth counterclockwise on the crank pulley from the white mark gave me a location after the two II notches on the crank pulley. That would be the closest I could get to the II marks no matter how much I tried, due to the fact that it was only one tooth over. I ran the engine one tooth over on the crankshaftgear from the white mark counterclockwise and the engine ran with no ping. I had a feeling that white mark was not TDC.
MY question is, are one of the II notches on d15b8 crank pulley TDC? I know I could tell for sure where TDC is by taking off the pulley and looking on the oil pump with the crank gear, but I do not have time to get the pulley off and check. Anyone have this prob with a cx d15b8? Also in the helms manual it says ignition timing is 12btc and all the other civic engines are 16 or b18btc I believe. Does that have anything to do with the notches on crank pulley because the cx motor is 12btc? The motor is stock by the way. I was also thinking maybe the belt was for a vx or si engine. Making it impossible to allign with one of the II notches. How much bigger smaller or bigger is the vx or si belt. Would I noticed if the belt was from a vx or si?

look again the timing mark should be by itself on the pulley.
since you pulled off the crank pulley and your looking at the oil pump and lower timing belt gear.
on the oil pump you should see an arrow/triangle align that mark to the mark on the timing belt gear.
if you still dont understand what im explaining move the crank til the crank pulley key is at 12 o clock.
now look around on the oil pump and the timing belt gear. if your observative enough you will see some markings.
that ll allow you to line up everything without using the crank pulley.
make sure the cam pulley is at tdc too and then your set.

first off thanks for the reply, I doubled checked and there is TDC mark on the crank pulley by itself. I know there is usually a mark by itself, but in this case there is isn't. There are five notches. First set of notches are in a group of three like this III and the second set of notches are in a group of two like this II. I did some searching on this board and another fellow member who has a cx d15b8 had the same exact prob as me. He had the same type of markings on his crank. I never had the crank pulley off because I don't have the tools right now and the time to do so. I would have checked the oil pump marking with the crank gear and prob would be solved. Anyone with a cx d15b8 had this prob? any input would be appreciated. Thanks for the input djhatch

Re: (JohnnyEF)
Do you have an adjustable timing light?
As in, one with a **** on the back, with numbers?
Nonetheless, just go with something placed on the piston. True TDC.
And the lines on the cam gear.

I actually do not have adjustable timing light. Thanks for the reply

You are correct. It's 16* BTDC. A couple inches towards the firewall is 0 TDC.

how much does a adjustable timing light cost? do you have any idea what is a cheap farely good brand? or where I may purchase one? Also If I used the timing light and set the timing light to 16* how would I be able to find the correct mark? Which mark would that be? TDC or 16btc?
Thanks alot appreciate your help

Re: (JohnnyEF)
$75 at Sears. (I think)
I asked about the adjustable light because you would be able to determine which mark of the two is 0* tdc by setting the light to 16*. Which ever lines up with 0* tdc is it. It would not be 16* btdc, it would be 0* tdc.
Then, if you set the light to 0*, the mark that is at 16* btdc (of the three lines) at the pointer is it.
If I could only explain a little better....
