My Holden statesman 95. The oil light on the dash bord is coming on and off, i know that is the oil pump or a blockage.. what is the best way to fix it?

They all work to a theme

Don't know what specifics your looking for. Try this link:

Aloha, ukeboy57

Should be printed on the cover

I am not familiar with this particular model but my best guess would be yes you would have to take it off.

mofre information required to assit

this is probably not what you want to hear but that light is there to allow the operator know that the engine has oil. and that it is being pumped to a adequate pressure to lubricate and protect internal components that have to be fed oil under pressure just to survive . if a engine looses total oil pressure a major seizior or blow up is on the cards often leaving most components un salvage able don't operate while the light stays on as you are doing damage . there may still be a bit of pressure there but not enough to lubricate the internals. first up check it has oil . peform a oil and filter change and see if that improves the situation but definatly don't operate as the noises soon turn into the death rattle and then the magic leaks out in the smoke leaving your wallet sore as well

Do you mean 7 rapid beeps and then 2 slow beeps? Google Holden body code 72 then

Turn Of After Warm Up

Your oil light is not a symptom. It's flickering because as the engine dies, the oil pressure is dropping. The engine's power pumps the oil, so this is pretty normal. The engine slows down, the pump will also, and there will be less pressure.
As far as what to try next, I would assume that a 1990 has throttle body fuel injection? (The kind that looks like a big 2 barrel carb) If this is the case, you should look to see if fuel is pooling on the butterflies at idle. If it is, then you have an injector stuck in the open position, allowing unregulated fuel to flow into your engine. If your engine ises direct injection, where there would be 8, or 9 injectors (9th would be the cold start injector), one or more of them may be stuck in the open position, but I would check the cold start injector first.
I'm sorry that I am not really familiar with your exact model. We don't have holden here in the states.

hi mate i have the same problem with my vs statesman did you get yours fixed what was it?
