timing on a d16z6 quick question for the experienced

I recently bought a 93 civic Si I noticed the distributor was set all the way off to one side so I checked the timing. I found the distributor is set fully retarded yet the timing light shows I am still several degrees advanced ( the 3 hash mark on the pully is 1/2" to the right of the checker on the timing cover). To me this means my mechanical timing is off..

My question is does anyone know a quick way to adjust the timing? on my talon I have used a thin sheet of metal cut the same width as the pulley and fed it in between the belt and cam gear this will allow yo to slip the gear and not take all the timing apart.

would soemthing like this work on the d16z6 as well. or is there another east way?

There is no quick way to adjust on a honda. Its easy to check though, theres little lines on the crank pulley that will put the bottom end at TDC, when its at tdc, check the cam gear and make sure the arrow is up. If its off a little, then its out of time. Not sure if this is a pic of a d16 series motor, but it is a honda and they are all similar. TDC is the line thats by itself on the crank pulley.

The above method will ensure that your camshaft timing is correct. Note in the photo that there are two marks on the crankshaft pulley. The white mark is a the tdc mark. this is usually three hash marks and sometimes has the paint worn off. The red mark is the three hash marks that inticate our 15 degrees before tdc. Since you are saying that the distributor is all of the way retarded on its adjustment, the top flange all the way toward the front of the vehicle, then you may be looking at the tdc mark with your timing light and not the 15 degrees before tdc mark. It also may be that your camshaft timing is off a tooth or two.

I would check your camshaft timing and then recheck your ignition timing. It helps me to paint the mark for 15 degrees before tdc with a yellow paint marker so it cannot be confused.

FYI. After my own investigation of the situation you can access the tensioner bolt from outside the cover, I loosened the tensioner slipped the belt off the cam and kept tension on it. adjusted the cam gear 2 teeth put the belt back on tightened the tensioner and done. I do not have a upper cover on so the whole job took 10 minutes and the car is back in proper mechanical time.
