If your wondering if your cam timing is off then, fifth pic down shows the gold chain link on the intake side coming up..that link is supposed to be ont he cranks when the cams are in that position....you need to rotate the motor over witht he chain tensioner in till the timing marks line up like that with the different color links above the dot on the cam gears..i dont remember how many turns but its a few....then the cams should be in that position your in now but all the chain links correct.
Hope i didnt read into this too much...maybe i dont understand the post???
looks like your intake cam might be one tooth off..you need to go on tooth to your right if your standing right in fron of it. how does it run in the position they are right now? also make sure the timing mark lines up perfect with the first line on the left on the crankpulley...
the exshaust one is off ...crapy pics. theirs one silverlink that is on the crank gear and two darker ones that line up with the cAm gears. the pics you show have the exshaust a 1/2 link off. the dot on the cam should line up with the colored link
how could only 1 cam be off if there are 20 rollers between the 2?
the car is perfectly fine in terms of driveability. But its half a second slower in the 1/4 mile.
I have a code 34 for knock sensor, if the cam is advanced, which makes the timing advanced, causing knock, would the ecu throw a knock sensor code because the engine is knocking? or just because the sensor is bad?>

cams are off a 1/2 link. that dot on the cam gear should be under the yellow link. and the crank pointer should be on the yellow (2nd over from the left) timing mark on the crank pulley.
today i just fixed a jumped chain in my spair motor i've been running. i pulled the crank pulley,oil pumpdrive and crank seal to see the crankwas off a 1/2 link. Crapy thing was i took the tomei cams out because i thought their was too much lift so now im back to stock cams
i see that the dots are not under the cams, i now know that they are supposed to be. My only concern is that i think the cams will be too far advanced like that. Wouldnt that definately cause knock?
The dowel mark on the exhaust ispointing up as it sits right now, if anything it is a hair advanced... so wont another tooth that direction make it that much worse?
what afastegg said about the marks. The dots should be in the middle of the yellow links. So you're one roller off. (though the FSM says the marks are silver?)
What is your ig. timing? If it skipped 1/2 tooth on the crank sprocket than the marks would be in the correct position. Did you just get the code 34 after the cam install? Your dowel pins are in the right position though.
The first thing i would do is check the ignition timing.

well when i check ignition timing, i unplugged the tps, started the car, revved above 3K 3times, then it wont go below like 1300 rpm, and the flashes are way off from all the marks.
When i plug the tps back in, and it idles, it reads 15 deg roughly
From my point of view, your cam gears and chain look just peachy. If -and ONLY if- in those photos the crank pulley is sitting on top dead center and the distributor rotor is pointing to the 5 o'clock position (down and to the right as you look at it from the driver's side).
you need to remove the cam gears and rotate them each 1/2 link towards the front of the motor as long as the mark is on at the crank which you can't tell, is there any problem with your ignition timing when you have it back together,ie where is 15* close to the middle?

No, from the pictures above, the cams are lined up. Just becasue the colored links don't line up, doesn't mean anything. Those are only helpful if you have the front cover off. If the motor is at TDC, and the exhaust dowel is at 12:00, and there are 20 pins between the dots on the gears, you are gravy.

ok guys heres the deal... the gold link is NOT underneath the dot on the crank
the first picture is a clear view for show purposes ONLY, just to illustrate whats going on down there.
the last pic shows the actual scenario, you can see the goldish part of the link.

yeah, forget all the colored links, they are really only useful when assembling a new engine. like eric said, get the dowel pins at 10 and 12 for the intake and exhaust cams respectively, and make sure there are 20 links between and you are all set. just make sure the ignition timing is set correctly and reset your ecu to get rid of that CEL.
