hi, ive got a punto mk2 2003,that the oil light comes on at idle, when you rev it it goes off, ive done a full oil change and filter. i know its an oil pressure issue, but not how to fix
any ideas peeps....

Not had a sump recently?
Oil pickup blocked?
Oil leak somewhere? As spray bar or a tollerance failing?
Wrong type of oil?

bought it from euro car parts with reg number so im assuming so, never had a problem with wrong type...
plus ive done the oil change because the issue was present prior to the oil change

Hi,
Can you give us any more history? Have you had the car long? Anything else happen around the time the fault started?
It my just be a faulty pressure switch. Cheap and easy to do and the first thing unless you have a pressure gauge you can put on to check the actual oil pressure.

Is there even oil getting up to the cylinder head / Spray bar onto of the cam?
If oils not getting up in a plentyful fasion....
Defo not a dodgey Switch? - there cheap as chips - i'd be tempted to throw one on it anyway, i know there not heard of failing like (unlike corsa's)
I'd be possibly having sump off to ensure no damage to the oil pick and that the tea strainer on it hasn't been sucking up something
joke is - the Previous owner may have run it low on oil, wrecked the engine.... and topped up to just pass while selling it...
What fresh oil went in?

10w40 oil.
bossch oil filter.
ill look into oil pressure switch..
should i try another oil flush too?

im taking it the oil pressure switch replacement would mean dropping the oil anyway??

Not really no - unless you wanna spend hours cleaning it up while engines running
Engine off and left for oil pressure / oil to run back down to sump - you should be okay
Simply Crack first one - whip out - slap new straight on in - and nip up
yo may dribble - but no biggie
access is okay - just dont forget the electrical connector

Sound..
I've got a few spare engines in garage so ill crack one off one of those..

So , yeah.... it was oil pressure switch. Put another on from spare engine and no more oil light.

Ive never heard of punto oil switch failing....
Rare...
But im hlad we saved another punto engine from been dammed

When a light is on it means that the light is on. Most monitoring systems are set up to fail safe so any one of a number of things will result in the lamp being lit.
Many moons ago I found a book in a dusty corner of a library about how to fly. Written for the RFC when it was mainly cavalry doing the jobs. Anyway the important thing was every day to open the throttle wide and see you get 1850 rpm against the chocks. Good all set to go.
Then one day you get 1800 rpm. The inexperienced pilot sends for the mechanic to fix the engine but the experienced pilot sends for the armourer to change the tacho. Hundred years ago and nothing really changed.

#The more modern reverse of this is power assurance checks on a Bell Jet Ranger helicopter. Engine won't pull required torque without hitting turbine gas temperature red line -Mechs call avionics to check temp gauge Gauge is OK, Mech does compressor wash, still fails, Asks avionics to check gage again, gets told it's actually at reading low tolerance limit- do they want me to adjust it so it's accurate (higher temp)
Back OT, don't know about pandas but incorrect indication of low oil pressure due to a faulty switch is not un-common. Wear and weakened pings all tend to lower the switch point.

Answer no -check the torque gauge, it's OK too. Finally mech splits compressor case and finds lining is worn so get an overhauled compressor at a cost that would buy several new Fiats. You can sort of understand them wanting to be sure, but how many times do I have to check the gauge before they accept the engine is at fault?

Well its just a ball on a spring aint it - when oil pressure is present the ball is unseated and breaking the connection
For all we know - there is an internal short due to the spring breaking -who knows
But Hey if a known old working unit says good to go! Its good to go!

OK well it seems there may have been an underlying issue... I have noticed a small oil leak. Can't 100% pin point it.. the join between head and block on timing side is lightly wet with oil. I have a drip that comes visibly from directly above the oil filter, from where the water inlet is on bottom of block.
The quantity is a drip every 30 seconds or so on a warm engine.
I've thoroughly degreased the area as was above normal build up of grime. Hence why I checked. Is there any none obvious areas for oil leaks to appear above the oil filter other than a head gasket or warped head...
Engine runs fine.
No mix of oil and water that I've noticed.
No pressurisation of coolant tank.

Probably totally un-related to oil pressure light. You need a big leak to put the light on.
