My oil pressure light has recently come on and stays on permanently on my 2000 w plate 1.2 sporting punto.

The oil is a little old and thin, but well within the specified level, I started the car up and with the oil filer cap off there is a little oil spraying across the cam, although more like a little spitting at tickover.

I had another nose round the car this afternoon and noticed the wire into the oil pressure switch had broken. Can this broken wire make the light come on, or would it make the light go out if that was the issue?

The car is going into a garage for something else tomorrow, so will ask them to do an oil pressure test as well.

Thanks, Lee

u need to repair the broken wire, as this will cause the light to stay on, as the sensor aint gettin any power

Can't really do an Oil Pressure Test - as there is a Big Hole at the top that goes into the Airbox

I'd just get a Family friend to sit in car while you hold the 2 wires together
if light goes out
Just Cut and solder it back together and leave it

Ah yeah good point on the oil pressure test. One wire to oil pressure switch only, so going to get another plug from scrap yard and solder and sleeve the broken wire to see how that goes.

Dont actually use the car regularly so have the time to check it all.

What sort of oil spray should I expect at tickover across the cam viewed through the oil fller just a little spitting, or more of a pulsed spray?

A sloppy spray is normal when viewed at idle.

Cheers

Don't understand this? Are you saying you can't test oil pressure because of the breather?

When testing the oil pressure, the gauge goes in place of the oil pressure switch, the same on any car.

And yes, if the pressure switch wire is broken, I'd start there.
