timing problem......oil light

if my timing is off would my oil senso light come on??? i was coming home and my gears slipped a tooth…and as soon as that happened my oil light came on…and my timing has been off…

I knw the timing is off because of the sputtering, my car idles weirrd as fuk, and i checked the lines on the gears and there off 1 tooth…but would that cause a oil light.

I know it can be the oil pump because it is less tha 3 months old(oem one), my pistons are str8…no smoke, so it should be ok… i hope its not a bent valve, which i doubt because the timing is off so it would be that b4 the valve…if not the timing, then it s gotta be the valve…

Could there be anything else…i am still confused about the oil light , y is it on???
