Yah, but if you didn't drop the chain, do it the FSM way

I guess i understand why you may have been confused, i didnt really understand exactly the significance of dropping the chain, but once you loose tension around the lower sprocket you have a big chance of putting your chain on another tooth... Then your timing wont be proper.

good read btw, hopefully down the road i can use the technique.

The chain cant jump anywhere from the crank sproket, even if its dropped, as there are two small retainers on the back of the oil pump, that prevents the chain jumping off , of the crank sproket.

That said, simply turn the crank a few times, to get the matting marks on the chain, to align with the the sprokets marks (that little dot), while you sit the cams in position, as per the FSM.

After you finish, turn the engine until you see them lined up again while the crank is at TDC (you need to turn it quite a few times) - then you can be sure you did it right.
