You can't have air. I would confirm the timing is correct before you go too far.

Did you use the timing tools to setup the camshafts? What codes did you have after replacement? Timing is critical as is the teeth on the crankshaft gear, the replacement of the timing chain tensioner and the guides. Are they all in spec?
