which way does the motor rock?

I need an answer quick, trying to locate the WB O2 sensor. Which way does the motor rock when you step on the gas?

I reason the cylinder head rocks towards the coolant expansion tank which make the crack turns clockwise viewing at the crank pulley. Please confirm.

Duh! I should had just calm it. Use your head!

The easiest to find this answer is to search for a photo of the belt. I actually thought of looking at it but only the wheel well cover is in the way.

Here is the answer - engine rotate CW so it rock away from the radiator as the tensioner is the last in the tensioned chain

If it rocks 'away' from the radiator, wouldn't that be CCW (if you're looking at the engine as shown)?
