On a 2.4, there are no timing marks...There are holes in the cam gears that need to be aligned with corresponding holes in the head.
Though it's not terribly difficult to do, it must be done precisely according to instructions or valves will hit the pistons and destroy the engine. You can find instructions for this procedure in haynes and other vehicle service manuals. (too long to write out here).
Remember...this is an exact install...you cannot just get close!!!
Good luck! Post back if you need further specific instructions with any part of the job.

YOU WILL SEE A HOLE IN THE CAM GEAR THAT A 3/8 BOLT WILL FIT INTO. PUT A BOLT INTO THE HOLES OF BOTH CAM GEARS. THEN LINE UP THE CRANK PULLEY KEYWAY AT ABOUT 12 O'CLOCK WITH THE MARK ON THE ENGINE BLOCK.
MAKE SURE TO COMPRESS THE CHAIN TENSIONER AND RELEASE IT WHEN THE CHAIN IS IN POSITION.
