I have a 2000 Discovery II SD with 83,000 miles on it. I had the head gaskets replaced at 72,000 miles, the only maintenance it has required besides normal stuff.
[/align]The truck runs great and the only problem I have is that when I stop at idle my oil light comes on. [/align][/align]If I increase the idle (slightly stepping on gas while stopped) the light goes off. It never comes on when driving.[/align][/align]I gave it an oil change today (synthetic Mobil 1) and the light still comes on when stopped.[/align][/align]At idle it appears that I am idling at between 700 - 750 RPM's.[/align][/align]Any assistance you could give me would be appreciated![/align]

 

Tried to call you, no answer, left you a message.

I have the same issue. Have you found out what was causing this?

Thanks

Dave

 

dropped/clogged oil pick-up tube?

 

What type of oil filter do you use?.. Have you replaced it recently?

 

When you changed oil and started it did it knock until you got
oilpressure?
It must be a loud knock.
If this the case you havemain bearings on the crankwith to much wear, this will make the oil light come on aidle.

If you don't have the knock I would check the oil sender.

 

Dave,
What year is your truck, how many miles on it and what brand of oil filter do you use?

 

I use MANN oil filters. It is a 2003 Discovery with 72,000 miles on it. Any thoughts you could offer would be appreciated.

My oil light did that on my last oil change, but quit after a few cranks. I'm still getting some rattle like a diesel at start-up. I think my remedy is to clean the pick-up tube initially, because with the problems you are having, same year truck as mine, I want to make sure everything is clear down there so if problems arise later I can look at the oil pump. It would be a good chance to replace my sump gasket.

Landzu asked about knocking, are you having any at all?
