What are the timing marks on a 1998 Mazda 3.0 v6?

There should not be any timing marks on a 1998 Mazda 3.0L V6. Instead, the camshafts are timed by the gears themselves, using a dowel pin to ensure proper alignment. You will still find timing marks on the crankshaft pulley and oil pump, which are used for setting ignition timing.
