That's pretty much the correct position for the crank. But you have to make sure the timing marks for the cams are in the right place as well.

So the mark on the intake cam should be at about 2 o'clock and the exhaust cam should be at 10 o'clock.

What he means by the camshafts flopping around is this. When you remove the timing chain, the valve springs and followers are still putting pressure on the camshaft and could cause it to rotate. If you have the timing marks on the cams in the correct positions the camshafts will be neutrally loaded and won't move by themselves.

And yes you turn the engine over clockwise by using the crank pulley bolt in the crankshaft.

made good progress today but i didnt get it done. im about halfway done. its my first time and nobody would help me so i did it myself.

im pretty sure i have good compression tho. i had the spark plugs out and rags in the spark plug holes to prevent any debris from getting in there and as i was rotating the crank one by one the rags shot out and made a pop noise. lol.

i also noticed that someone must have been lazy in timing my motor. my colored links dont match up with the marks on the cams or crank. lol. they are all one tooth over, but theres no ill effects of that except my cobalt is "special"

LOL, they will line up eventually. the colored links move each time the motor rotates.

Yeah... you better make sure the marks line up when you first time it.

But if you expect them to line up again.... you better be ready to rotate the motor a bunch.

I think I'm finally getting a grasp on this. It just seems too easy, so I'm trying to make it harder than it is. Seems like the best way is to remove the timing cover and remove the chain before pulling the cams.
