I have an 03 disco w/ the 4.3 and the GEMS. When it idles after it gets completely warmed up, I am getting a blinking oil pressure light. I tried changing the pressure switch. I flushed the engine and changed the oil twice. I am running 10w-40, non-synthetic. Still getting the blinking light. If I raise the idle slightly, the light stays out. It only has 60K on the engine, and the oil was changed at least every 5K, normally at every 3K. I can't imagine it needs a new oil pump. I do not have a pressure tester. Could it be something simple like the PCV system? Please let it be that, I can't spend the approximate $2,000 to change the oil pump.... Please get me some good advice.... Thanks.
Oil pressure problem?

I just went through this with my 3.5 litre V8. Oil Pump gears and a new oil filter housing (half of the oil pump housing) fixed me right up for less than $100 and a bunch of shop wrags. Your engine has a different oil pump configuration than mine - so your resuklts may vary.Firemanshort
