ok, i was changing my timing belt today and was putting the crank at TDC and noticed the TDC mark on my cam gear was about 1-2 degrees away from the TDC mark on the rear timing cover..

right now with the crank at TDC, the cam gear needs to move counter clockwise a couple degrees to perfectly line up. im guessing as it sits my cam timing is advanced...or is it retarded? is it usually better to be advanced or retarded or at zero? (i know...only a dyno will tell)

now, ive been running it like this for a year now. the block has been decked and the head has been resurfaced a couple times so im guessing that is why it looks a little off ?

question is. if everything has been fine, should i just leave it like it has been or buy a adjustable cam gear, degree the cam, and make sure its at 0 degrees?

Your cam timing is retarded if it's been milled/decked. It's obviously fine as is, and you already answered the rest.

just from what ive read, ive seen that the 59300 cam likes to be retarded...

hmm, leave it or get it to 0 degrees.

I thought the 59300 likes to be at 0?

who knows, ive heard it all... advanced, retarded, 0..

i know the only way to tell is on the dyno, but i dont plan on hitting the dyno again until i get my intake manifold/throttlebody...and wont have the money for that, dyno time, and a cam gear for awhile...its xmas time.

if everything is fine why mess with it. get a cam gear and go to the dyno if your worried.

i thoguht maybe set it back to zero and i would maybe gain more power than how it has been retarded this whole time. like i said i cant do the dyno just yet so i was just wondering if i should leave it retarded or buy cam gear and goto 0.

mike93eh2

if my cam timing is retarded a good 2-3 degrees right now, do you think if i set it back to zero i will be making more power?

sohc d16, zex 59300 cam.

We really can't answer as you have said earlier. Dyno is the only way to tell. If you do get a cam gear and change the setting just make sure you reset the ignition timing to Match hondata setting (usually 16 for Z6).

well turbod16 seemed to answer it.. 0 degrees is what this cam likes. all i needed.

You should always degree a aftermarket cam in using the supplied cam card.Even if the block and head has never been resurfaced or milled. The bigger the cam the more critical it is to degree a aftermarket cam. Thats what a adjustable cam gear is for.

what method owould be best? do you want to just find the lobe center?

PHDZINE

On a single cam I would use lobe center method. On Dual Cam I use the overlap method. After you find lobe centers, you will know exactly were the cam is in relation to the crank and you can advance or retard the cam wherever you want...but make sure you have the proper valve to piston clearance.
