!!!!!???oil light???!!!!

[markovr]

If its coming on consistently only when you brake and the oil is full (this is usually caused by low oil level since braking takes the oil away from the pickup in the sump ) you need to probably change the switch first and if it still happens connect a gauge to the sender hole and try to bring it on when you are driving. Sometimes the relief valve in the pump can stick also causing this or a broken pick up pipe sucking air when the level drops under brakes....a clogged one would cause it to happen at other times so I don't think it could be that.

went to repco the other day and it only cost me $15.70 for another oil switch

How easy/hard is it to replace?

Not hard at all, all you need is a shifter and just unplug the wire and unscrew it and screw the new one back in and thats it. it will drip a bit a oil when u do this but just have a rag there.

If I break hard my oil light flickers on and off...My assumption is that its the oil moving away from the sensor, as its basic physics.

i would be cleaning the oil pick up, i break hard most of the time and don't have that prob

Basic physics in this case means that when you brake hard, oil in your sump will move towards the front of the sump...which is where the oil pickup, oilpump and oil pressure sensor are all located. If anything, there should be less chance of oil starvation under severe braking. As Markover has mentioned, faults such as this point to a suspect oil pressure sensor. This is a lot cheaper and simpler than pulling the sump.

Fair enough. I ahve very little knowledge of the locations of these sensors, parts, ect... Im not exactly mechanically minded. I just assumed that it was at the back, as it provided a logical explanation to the problem.

Either way, you recon i should check out the oil pressure sensor, eh?

Replacing the oil pressure sensor would make good sense - though first I'd remove the connector and make sure it is making good contact....maybe under braking the wiring/connector moves and breaks contact causing the oil light to come on. Always go for the simpler options first.
Most cars do have the oil-pickup at the rear of the sump and can have problems with oil surge however not the Commodore V6.

Hey!

Sorry to bring this topic back up again but I was just reading through, and I have the same problem again... however I noticed the light only comes on when I hear this weird ticking noise from the engine... is that related and could define exactly what my prob is...? I am assuming low pressure though because sometimes when i accelerate the light goes off but i dont want to seize my engine :cry:


I will do all the check listed above. Hopefully its something minor but its the ticking noise that worries me.

thankyou for any help in advance
