Where is the oil pressure sending sensor located on a Chevy El Camino?

Answer 1

It probably has nothing to do with low oil LEVEL. Oil pressure is directly related to the condition of the crank and rod bearings in the engine. Change the oil immediately and use a thicker oil. If you're currently using 5W20 oil change to 10W30. If you're using a straight grade oil go one or two numbers higher. Another option is to use STP or some other oil thickening agent to squeeze a few more miles out of the engine. Low oil pressure is caused by excessive wear on the rod and main bearings. The rod and main bearings float on a film of oil. There is usually less than the thickness of a human hair between the bearing surface and the crankshaft in a new engine. When the bearing gets worn, that thickness can be many times that. Pressurized oil is pumped through "journals" in the crankshaft to cause the bearings to float on a film of oil. When the oil gets old it becomes less capable of lubricating. When it gets dirty it acts like an abrasive and causes wear on the bearing surfaces. It's very important to use good oil and keep it clean. With good maintenance an engine can go more than 400,000 miles without touching the heads. Unfortunately, your problem is probably not the sending unit. But just to be certain, connect an oil pressure gauge and see what it says. If the oil pressure drops after the oil warms up, it's bearings.
