Low Oil Pressure While Braking?

[nizmo_freek]

Hey guys

Not sure if this is the right section or not but anyway.

I done a bit of a braking test yesterday to see how well the abs worked (stupid i know, but i was curious to see how well it worked ) so i was doing about 100kph then put the brakes on as hard as i could, while coming to a complete stop the oil light came on ( the little oil can symbol that lights up red on the top right hand side of the cluster) i didnt keep my eye on the oil pressure gauge so i dont know what it was reading.

Is this something i should be concerned about ,the oil level is just above the full line, my old r32 gtst actually done the exact same thing. I am using the stock brake setup with 235 front tyres, so somehow i dont think this would be enough to cause oil starvation while under hard braking but please correct me if im wrong.

Any comments would be great

Cheers

Depends, If you were pushing it real hard before you started braking, then you've probably got a lot of oil in the top half of your engine, then the braking might be enough to make it appear as though the level is low?

Although I'd imagine that the GTS-T sump is fairly well baffled?

Your oil level should be on the top line of the H at all times.

check it and add a litre

sorry to hijack but there is a H and L with the mesh bit in between

where exactly should the oil level be?? over the H? or on the line where the mesh stuff stops??

it doesnt hurt to run it over the full line to keep it safe. there may be other issues with your oil control system to cause it to surge under breaks..

Nope i wasnt pushing it, was just cruising at 100kph then put the brakes on.

As i said above the oil level is quite a bit above the full mark.

Yea i always run the oil level a bit above the full mark in all the skylines ive had, any ideas on what other issues there might be? The sump is in perfect condition (no dents etc) and i change the oil and filter every 4xxxkms ,i use castrol magnatec 10w40, the car has only done 86xxxmks.

As i said above my o0ld r32 used to do the exact same thing, is there anyone willing to go and test it on there own car to see if the same thing happens?

it COULDjust be the sender/gauge combo playing up... best to chuck an aftermarket one on there and verify it

[WazR32GTSt]

the common oil pressure sender fault usually manifests as a problem with the pressure reading, but i have never heard of the oil light coming on with an oil pressure sender issue...

i would be keeping a real close eye on it

if you ever see the light again, shut the engine off immediately

but if it were me i would be considering getting an expert opinion, because if its the oil pump that is dying and you don't fix it, you could be up for a new engine..

[WazR32GTSt]

ps testing out the ABS is a great idea, you need to know how it works..

but from 100kph? that's a big test! you should be able to engage it by slamming on the brakes from 60kph-ish i would have thought

the oil press light is driven by the sender also... so if thats faulty then its going to makle the light and guage read wacko
