You might have to rotate the crankshaft another 360 degree. Remember the crankshaft have to rotate 720 degree for the cam shaft to rotate 360 degree.

beat me to it. Cams spin at half the speed of the crankshaft. So by that, you would have to turn the crankshaft 2 times for the cams to turn once. so yes. turn the engine another revolution

DOH!!! YOU ARE TOTALLY RIGHT!!! I've done this many times with my 2.7 and it does need another rotation to get the larger holes to line up on the opposite side. I'm such a fool! The C4 is all new to me so I guess it just slipped my mind. Thanks for the reminder.

Really? I'll give it a shot. Although I just received the cam alignment tool in the mail. I've replaced a number of TB on the 2.7 with out the crack locking pin tool and it's fine. I don't think the crank lock tool is really necessary, just insurance I guess.

They are not! This was the problem all along! See my other post about fans not coming on.
