Hi all, today I was driving in highway and everything was going well....when I came back in city when I arrived at first light and had to stop I took a fast look to the gauge cluster and noticed a red light so I worried and turned off the car.
Then I restarded it and no lights went on...after a while I started to run again and when I stopped again I saw the engine oil light on!! >> >>
So I parked to analize the problem.
I shutted off again checked the engine oil quantity and was ok, not full but ok and no oil leaks at all.
I started again and no lights on but after about 10 seconds running at idle the light came ON again >> >>
I noticed that if I just rev to 2k or more RPMs the light goes off so the pump at 2k + RPMs work.
I thought the following possibilities:

- Oil sensor not working good.
- Oil pump not working
- Oil pump dirty

What do you thing guys???????????????? >>
HELPPPPPPPPPPPPPPPP

2 possibilities, bad sensor or low oil pressure. I would get a gauge and screw it into the block (may need a flex hose to do this- all parts avail at parts store just need gauge, hose and any adapter fittings ) If pressure is really low, (anything above approx 10 psi at idle is ok), then start worrying about eng probs. could be the oil pump, or more likely the oil press relief spring. or prb in oil system, I have seen other engines pop out a plug at the end of an oil galley, thus losing press at low rpm, not sure if this would apply to your eng. some of the plugs screw in,
Last thing to check, or maybe 1st if press is truely low, is it running excessively rich to the point fuel is going past the rings and diluting the oil to the point it is too thin?

I've to tell you some thing about my engine condition:
like u can see in my profile it's pretty hard modded as a NA engine....
2 months ago my car started eating much oil, like a quarter each 700 miles, I'm pretty sure cause I have bad valve stem seals.
Anyway...I noticed in those 2 months when I start my car the oil check light doesn't disappear immediatly, but after 3 or 4 seconds and I can hear by the engine sound that just when the light goes off the oil reaches the head...so 3-4 seconds with no oil flow at cold start.......
It aid me to think that my oil pump is clogged or jammed..... >>

what your describing sounds exactly like what happened to my car about 3 weeks before I threw a rod. and when i took apart the block the pump had clogged. hard to tell for certain though cause of how much damage the rod did to everything.

Yes, I should have read your profile 1st, you may have some serious prbs inside, especially if it just started using all the oil, using that much, I suspect it got hot and the rings are now bad, I dont think the valve seals will use that much, but I could be wrong. with all that work in the engine, why dont you already have gauges in the car? either way, I think you should be taking a serious look at things before it gets any worse.
Also make sure you have an oil filter with the anti-drainback valve in it, helps to get oil to the upper end faster instead of having to wait for the oil filter to refill every morning.
