what causes no oil pressure and tick in 97 dodge

If you are checking it with a manual pressure gauge and not reading pressure at all, clean the port where you're connecting the gauge to. If low or no pressure after verifying port is clean, check to see if oil is too dirty (Muddy) if it is, change oil. If still no pressure with clean oil, bad oil pump or bad engine

The ticking is caused by lack of oil pressure. (no lubrication)

ok the ticking just started after the oil pressure dropped to nothing. Do you think its probably oil pump it has about 176,000 miles on it

Well it's worth a shot checking the pump first than having to replace the engine

Check the shaft that goes inside the distributor, that's what turn the oil pump

when the pressure drop i didn't hear any ticking until i crancked it to move it to my back yard. When the oil pressure dropped i only drive about 2 miles before.

You can't run an engine with zero oil pressure, you'll ruin the engine if it wasn't arealdy
