Was Driving yesterday and giving it a bit of a hard time then about 5 minutes later i was cruising and the oil pressure went to Zero and the Oil pressure light came on so i switched the car of straight away and just sat there for 5 minutes thinking why me! Fark and hell i hope i havent done any damage so left the car at my girlfriends house and now been stressing all day about it.

Im getting the car towed tomorrow to my mechanic to check the pressure and hopefully its alright its basically a new motor new turbos i had it dynoed last week to make sure everything is running safe abd not to lean and my mechanic said i had nothing to worry about the engine seems very healthy. Lucky it wasnt on hi boost was only running 10psi.

So pissed off i have had my gtst for 7 years not 1 problem had the gtr on the road for 3 days and was really enjoying it and now this! Words cant express how pissed off i am I was hoping to wake up this morning and i was having a bad dream but thats not the case.

Does anyone have any good news for me like maybe its nothing to major and im stressing about nothing?

Cheers any help appreciated.

the oil pressure sender unit in the GTR is shite which makes the guage read all over the place. As for the oil light, thats a different story im pretty sure it runs independantly and if it comes on its not good. It could always be a electrical issue though

how was the car behaving? normally? weird noises ?

smart man for switching it off straight away. I know how tempting it would be to fire it up again just to 'see' what it's like. but sending it to the mechanic is the way to go.

did you check if it had any oil?

eitherway, if the engine has only been run for 3 days and went through that oil thats a problem by itself.

They'll just stick a mechanical oil pressure gauge on it and see what it reads. Hopefully its not a buggered oil pump

It didnt go through any oil there is still 4.5L of Oil in there so its not low on oil and its not overfull and the oil looks alright, Its going to get towed to my mechanic at lunch time and we will check the oil pressure I just hope it didnt spin a bearing or something i will be so pissed considering it would have done no more than 2000kms. What would be the best case scenario? Is there any chance it couldnt have detsroyed my motor?

Best case is it's a problem with your oil pump and you replace that, which is in fact most likely the case I reckon.... If you turned it off quickly after it lost pressure, you might not have damaged anything at all >_<

yeah i hope so but it may not have been quick enough as soon as it happened i was around the corner from the misses house which was like 50 metres so i limped it there as i have had my gtst stripped twice when i left it out the front so wasnt going to do that with the GTR but i hope it didnt do damage that quick.

I checked the oil cap to see if there was oil in the head and there was a bit it is going to get picked up soon so i will find out shortly.

What an idiot i bought the car rebuilt so i expected him to change the oil pump if he rebuilt the motor i know i would have but i hope he hasnt taken a short cut and left the old peice of shit standard one in.

50m with no oil pressure should be okay, if it spun a bearing because of that i would be extremely suprised. I would say you will be ok, but thats if you lost oil pressure, theres still a chance that you just have a faulty sensor (although unlikely).

I had a mate, who wasnt very mechanically minded, and he tried to do a oil change on his skyline, anyhoo he didnt tighten the oil filter very well and it came off while he was driving. As you can imagine he lost all his oil, and no pressure and drove it a good 5mins home (stupid). All he did was top it up with oil, put a new filter on and even to this day its still going strong. As long as you werent belting up on it, it should be fine

Like i thought we checked it with a 2 mechanical Gauges and absolutely no pressure what so ever so definate pump failure, but going to have to drop the motor and check everything to make sure it hasnt done any damage to any of the internals.

I had a bad feeling as soon as that light came on i just hope i dont have to fully rebuild it again and i can get away with minimal. Going to purchase a N1 pump and the Tomei oil restrictor mod is already done and might as well put a sump baffle in to ensure this never ever happens to me again! How labour is it going to cost to get the motor in motor out on my car? Deciding whether to take it to a friends workshop to get it done but its a while away from where i live but if its cheap enough might take it to a work shop closer to me. Im trying to figure it out i just want it back on the road and its a crap time of the year to get anything done with christmas and new years.

If he had a spun bearing he would know it, she would have a very loud knocking. When you run the engine without oil I can tell you will do some damage to the bearings because there is no oil there so the bearing will be rubbing on the crank, if you take the big ends out you will see the markings on them . This doesn't mean that they are stuffed, in a normal ( none high performance engine) could run like that for years but in a boosted RB26, I don't know how long she will last .

Yeah why its out i will probably replace the bearings and make sure everythings that looks worn is replaced and it wont go back in unless its 100% fine. But im still hoping it was only the pump thats stuffed or maybe a squirter came loose just going to have to pull it out and find out. I'm not happy the reason i bought a rebuilt motor is so i didnt have to do this and for it to be reliable oh well shit happens.

What oil pump do you guys recommend my mechanic said the N1 pump and i am leaning towards that way at the moment also looking at JUN and TOMEI but there double the price, Can anyone shed some light on which one i should go for? cheers
