TDC vs Distributor

Hi I have started to change the T-belt on a 3.3L the vehicle was running terrible, but made it into the garage. I have the top cover off and can see the t-belt is missing teeth and pretty loose but still in one piece.

 

When I turn the crank, the dist is nowhere near pointing in the direction of the #1 plug, when the timing marks on the crank are near the indicator.

I have a piece of wire in the #1 cylinder and can see the #1 piston is at the top, when the crank rotates to align with the timing marks but the FSM says dist should point at #1.

 

Silly question but should I just continue to rotate the crank until the dist/crank line up? Or, is there something I am missing?

TDC on the compression stroke. If the rotor is pointing in the opposite direction, its on TDC of the exhaust stroke.

 

When the piston is coming up on a compression stroke, you'll hear air hissing out of the plug hole as both valves will be closed.

The timing marks on the crank pulley? They line up with the pointer every time No. 1 comes to TDC whether its on compression or exhaust. Make sure you are aligning the furthest LEFT timing mark with the pointer.
