R33 Skyline that thinks it may have no oil pressure!

[jjcodex]

Hi all

You cant believe my friends luck!

He has a R33 Skyline that is due to go to the ring tomorrow. Whilst driving today, very suddenly, the oil pressure gauge dropped to nothing, and the oil pressure warning light came on. Combined with this, at the same time, I suddenly lost boost.

Now obviously it could be that the oil pump has packed up, leading to the faillure of the turbos, but I am curious as to whether there are any other things that can lead to these apparent symptoms in this car (ie electrical issues).

I only say this becuase the car was put through a car wash only about a mile before the sudden failure.

Desperate!

Help!!?>!?!?!?!

Well....do they all use the same sensor ?

Verify there is actual oilflow, or pressure with a suitable mechanical gauge.

I'd imagine the car's light, and any auxiliary gauge use 2 separate sensor/switches....so unlikely both have gone bad ??

Although you never know.

Did he stop the car when this happened, or did he drive on ? if so, how was it driving ?

Hi Stevie

Sad to say that the gauges appear to be correct. It would appear that for whatever reason, the car has had total oil pump failure!!!

I have to say that I am stunned! This is the sort of failure that I expect from a shonky old Ford, and not a Nissan R33! Goes to show

Next step is to rip it apart I guess to see what has caused it - but the turbos I suspect now are systematic, ie fked.

perfomance cars take a lot of looking after as you will find out, skylines are money pits and prone to oil pump failure .

i would upgrade with either a jun oil pump or n1 depending if standard .

think greenlinejp or newera are cheapist place to get them when i looked around ages ago .

There have been recent threads on the skyline forums of both the Jun and N1 oil pumps failing very shortly after fitting !!

For stock car i would personally fit a stock pump
