can I unplug the oil pressure sending unit to stop the lite from flashing and the dinging of the chime driving me nuts.
No if you unplug the oil pressure switch the oil light will stay on steady, the cheapest probable fix would be to replace the oil pressure switch. If not you may have internal engine problems.
When it comes to oil pressure problems it is better to fix the problem correctly. It will cheaper then replacing the engine.
