Low oil pressure warning when braking hard ?

[immortality]

Hey,

As the title says, took a VT S L67 for a spin this afternoon, thought I'd give the brakes a good test run so I got the car up to about 70km/h and stood on the brake hard. The nose came down and I was just starting to get a little brake lock up when the engine oil light came on with a chime so I got out of the brake. Pulled over just a little bit later to check the engine oil and the sump was full, if anything over full.

Anybody ever experienced this before?

Only when oil level is low.
Maybe oil is a little thin and moving away from pickup or pickup is partially blocked.

if the sensor is working properly then it'l only come on with less than 10psi of pressure from memory. Though really id fit up a proper sensor and check the real pressure.

Check your oil pressure and preferably under the same circumstances. Might be a large bit of sludge moving around in the sump. I found exactly that in a VK once.

the pressure switch is likely. non genuine ones typically fail in 6 months. I had the idiot light come on early last year and it just was the pressure switch.

I was thinking of buying it but going to give it a miss.

Had brand new oil in it plus new coolant. Started having a poke around, under the radiator cap there was a slight coating of milky coffee coloured slime, very oily and the same on the coolant expansion tank level indicator so I think someone is trying to cover up a possible engine issue. Engine did actually run very well otherwise.

that sir would be the lower intake gaskets. They have a habit of leaking oil into the coolant rather than coolant into the oil.

Either that or a good dose of bars leak shit

yeah definitely sounds like something you don't want to have to deal with after buying a new car!

It would have to be a very bad case. I've seen plenty of ecotecs with old intake gaskets but this one was more milky than you normally would see on the radiator cap and in the expansion tank. Best case intake gaskets, worst case......
