Why does my 6-cylinder Dodge Ram Van oil pressure light come on or flicker and pressure gauage shows a drop but van does not turn of and the pessure goes back to normal?

Answer 1

My oil light flickered until the engine failed at 75,000 miles. Check the oil pump. Some one else wrote:

oil pump went out around 30,000 miles. The oil light came on every time I turned to the right. After checking the oil level and finding it full, I took it to the dealer. They said all was fine, but after the engine started knocking, they replaced the oil pump. Around 50,000 miles the light started coming on again, the pressure would drop to zero, but after a few minutes come back up. I replaced the oil sending unit and that worked for awhile. At 70,000 the AC went out. At 90,000 the AC went out again. Now I have just replaced the oil pump again last week and the oil light is coming on again.
