hi guys,

my car is leaking engine oil from driver side of the engine bay.. initially thought it was oil filter but no sign of leak there.. not power-steering since oil is different.. are there oil lines on the drivers side.. how can i find out if the oil pump has crapped out.. will it squirt oil if it does die.. tried finding a split hose but couldnt.. seems to leak once car is under-load.. oil pressure stays aroung 1/4 mark as always.. wot else should i be looking for?? seals etc? oil seems to spray.. was all over the battery portion along the middle and just past the struts(?).. :D

Power steering fluid will find its way around to the drivers side quite easily. Mine does when it gets too hot & I have put too much into the reservoir. If it is red it is probably just that.

With regard to the oil pump, no an oil leak is not a sign of impending failure.

Remember that the oil filter, if it is leaking leaks on top of the front diff. It is unusual for it to get hosed all over your strut tower, hoever.

My bet is that it is power steering fluid. Check the level & maybe empty a little out. If the problem goes away you have found your man.

i dont have any relocation kit.. the leaking oil was engine oil.. isn't the power steering oil different? does make sense that one of the belts might be splashing the oil around.. not a lot of it had leaked onto the ground..

PS is red and smells different to engine oil

just an update guys.. it seems like the dipstick was the culprit.. it was pushed up a little and there were oil marks on the underside of my bonnet.. it is still leaking drop here n there if i leave the car overnight.. checked underneath the car on a hoist and there's oil splash all over the exhaust and gearbox.. it could explain the overnight dripping however my concern is that i have another oil leak somewhere.. is it normal for so much oil to be splashed around like that..

i have also been told this is due to blow-by(?) and i need to install a oil catch can to overcome the excess oil.. is this correct.. i know R32 gtr's have oil problems.. is this a common solution.. wot bout oil coolers.. my car isnt for track use.. cant think of anything else.. does anyone know hoW i can check gearbox oil? thanks

My car used to push the dipstick up on occassion, but it turned ot the rubber corrugations on the seal at the top of the dipstick were worn smooth. So i bought a new one from Nissan and it hasnt happened since. The dipstick used to pull out too easily, but the new one has a nice firm fit. For street use, as long as your not on or near the limiter alot, you dont need coolers or catch cans.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
