Question about Cars & Trucks
Did the old chain jump time or break? I think this is an "interference" engine, which means if the cain had jumped time or broke you may have internal damage--bent valves, broken pistons, etc. If the engine turns without bad noises, you might run a compression test to see if big damage exists.

Usually there is a dot on the crank gear and one on the cam gear. Crank is up and cam is down but you still need to make sure you have TDC=top dead center

Have you checked compression in those cylinders? I would bet they are low and the probably cause is bent valves from the broken timing chain.

SOURCE: Timing chain not marked truck
there should be a corresponding mark on the wheel and on the cover. what specifically is your engine? the marks on the wheel could be a punched rounded mark while on the timing belt cover the mark looks like it has been made by a hacksaw when #1 piston is on TDC youre closest to the mark. you can also crank the cam wheel to the cycle where its on ignition stage-this also is the closest to the mark
