Default TDC mark, there are two !?!?

I'm not new to Honda's , and I usually don't post a lot of problems. Anyways I am tuning this car, and for some odd reason there are 2 white tdc marks. Has anyone ever encountered this ? Someone suggested it was a chip in the pulley, and its not. There two identical marks about 2 to 4mm apart. Any ideas on whats going on ? Which one is the right one ?

If it wasn't dark out I would measure it for you. I can check out the distance for you tommorrow morning. I have to fix my cam timing because its 180 degrees off.

d15b2 , a lot of customers normally don't have major work on these. But measure the marks on the b16 and let me know what you get, thanks for the help. I still am scratching my head trying to figure out why there are two marks.

I'll let you know in the morning. Yeah that is an odd motor to do performance work on. Maybe you can help me with my question.
I installed an ls distributor on backwards on my b16, so now apparantly my cam timing is 180 degrees off and the car won't start. Could I loosen the timing belt tensioner up and only rotate the intake cam 180 degrees. Instead of timing everything apart. I'm wondering about the piston to valve contact.

You can install a distributor backwards, that's new to me. I only thought they were made to go on one way.

Anyways there is only one way to do this, and do it right or you might pay in the long run. Take the timing belt off, and get the crank at tdc, go nice an easy, if it will not turn, do not force it. Once you get the crank at tdc, align the cams, but once again be careful not to force the cams.

I'm sure I could word it better, but I have been up and working way to long.

You can solve this with a protractor. Go out to the pulley and find the first red mark. T. This should be 14 degrees BTDC if i remember correctly. Use the wheel to find 0 degrees and there is your TDC.

Certain Honda distributors are made so you cannott install them 180 degrees out. They wont sit flush. I cant vouch for all of them however.

Well thats just what I'm going to do. I changed the water pump, timing belt, and tensioner a few months ago and I couldn't get it at TDC, but evently I did the crank pulley kept moving. Well can't I just put screwdrivers in the cam shaft holders so they don't move when I have it at TDC.
