Want this question answered?
The timing marks are dots on the ends of the camshaft and crankshaft. They are on the sprocket ends where the timing belt or chain connects. The dots should be pointing towards each other for proper setting. The cam dot should be pointing down and the crankshaft dot pointing up. The dots or marks can only be viewed when the timing chain cover is removed. hope this helps...
The camshafts are marked on both ends, as shown here:http://www.rdtiburon.com/index.php?showtopic=29801
there should be a number stamped on the front of the camshaft. provided you know the manufactorer, go to their website, type the number in and you will see whats called a Cam Spec Card with all duration, lift, and lobe seperation.

they should be pointing down in the water
You have 2 notches on the timing gears one on the camshaft gear and one on the crankshaft gear. Align them so that the (top) camshaft gear is pointing straight down, and at the same time align the (bottom) crankshaft gear so that it is pointing straight up. The two marks should be perfectly aligned with each other. I almost forgot, make sure your # 1 piston is at "top dead center" before doing this.
The easiest way to find it is to set #1 piston at TDC and see where the rotor is pointing, it should be pointing to number 1 terminal on the distributor cap.
The number '8' should be written as the digit '8'.
With proper maintenance, the camshaft should last the life of the engine.
A striaght line drawn through the cente line of the camshaft and the crankshaft should line up the cam sprocket time hole (pointing down) the upper and lower marks on the chain damper and the crank sprocket time mark (pointing up). Simple, right?
The 2003 Saturn camshaft sensor can be found on the back of the cylinder head. The camshaft sensor should be labeled as such.
When the #1 piston is at TDC./ TOP DEAD CENTER on the compression stroke the rotor should be pointing towards the #1 cylinder when the distributor is installed correctly.
