Guys,,
I'm verifying my CAM and Crank Pully timing for the very first time. To make it easier i rotated the engine by crank pully until i got the piston at TDC and CAM timing marks aligned.

Now the issues:

CAM:
I have stock cams and i just noticed that there were two indicators on each cams therefore i marked them WHITE. TWO are facing eachother and are aligned and other two are on the outer rings (like 180 apart) this can also been seen in the picture. Does this timing setting looks ok?

Crank:
I was not able to identify the timing marks on my crank pully, although i found two very small Cuts on both sides of the inner half of pully. So i'm assuming these are the timing marks. is it correct?

Distributor position looks odd to me.

I've attached pictures for your reference. Let me know if i'm making a mistake in marking/identifying the marks. Your help is needed.

Pictures are a little blurry, but in the first picture, I dont think this is the correct aligning. The cams have these chops near the bolts where the cam gears slide on top, and when cyl. 1 is at TDC on compression cycle the two chops are at 12 o'clock and then you have the markings on the cam gears line up - exhaust at 3 and intake at 9 o'clock.

The crank pulley marking needs to be aligned with markings at 10 o'clock, located on the lower timing cover.

You cam angle sensor - CAS /distributor/ can be adjusted with a timing light after you're sure that your base timing is correct. It's the green top kind - optical sensor. Some people upgrade to black top CAS, because of OBD2 conversion problems /random misfire/, but you dont need to worry about that since OBD2 is mandated in the US only.
 
You mean camshaft dowel pins? hm... i was confused between the marking on cam gears as well. ok! let me align the dowel pins at 12 oclock and recheck timing.

As for the crank pully mark, where should it be aligned? i assume at T mark on the cover??
Correct me if i'm wrong
 
Cool!!
just rotated the pully again and everything was aligned properly. Cam gear timing markers were rightly aligned and so was crank pully mark which is rightly aligned with T marker on the cover. I also grounded the timing connector thru my DSMLink and got my Ignition timing double checked. Perfectly Fine!!

CAS is in the position as shown in the Third picture. Does it looks ok to you? Although its rotated too much towards the firewall but as far as the ignition timing is correct who cares! right?? i hope there is nothing to be worried about its position as in the pic.
 
Well your base timing is correct, but the way the CAS is set, I believe your ignition timing is retarded, but if car runs fine then leave it there
 
Exactly!! this was my concerned as well. but this is the position where i saw the timing marks on the cams aligned with the timing light. So i assume this is the 5* marker.
