How many revolutions can it take to align timing marks on the 3.5?
Seems like I've been at this for an hour (manually cranking the engine). The engine is from an '02 I35 and there are two yellow links and one orange link on the primary chain. In the FSM, it states that the yellow links must line up with the punched mating marks on each sprocket and the orange link must line up with the notch on the crankshaft sprocket. Also, the cam lobes nearest the timing chain on the right bank are supposed to turn inward (at roughly a 45 degree angle) facing each other. Also, the gold links on the secondary chains are supposed to line up with the mating marks on each outer cam sprocket. Lastly, piston #1 is supposed to be at top dead center at this point. MY QUESTIONS: How long can it take to make all this happen? Does all of this need to happen? Help...I'm gettin' tired! Thx.

Just curious about this because I did not align the colored links, but at "TDC" my cams were at a 45 degree angle.

Well there is a TDC for the compression stroke and the exhaust? stroke.

As far as I read in other threads it did not matter which stroke as long as it was at #1 TDC. All I know is I got the marks in the correct spots.

So generally speaking, you should turn the crank to the nearest TDC then start connecting the chains regardless of if it's on the compression stroke or not.

That's exactly what I was thinking. #1 TDC is #1 TDC. as long as all the sprockets are installed correctly and everything is lined up with the marks on the 3.0 chain per the FSM every swap shouldn't have a problem with timing being off, as long as the #1 piston is at TDC.
