Burning (oil?) Smell Through Ac

Hi guys,

I recently purchased my M35 250T RS privately and am based in Canberra.

Today while driving home from work I noticed a distinct burning-oil-type smell coming from the AC vents that disappeared when the AC was turned off. Additionally, when I pulled over and opened the bonnet I could see a faint smoke (if you will) coming from the passenger side near the dipstick. The car was only recently serviced on Tuesday last week and the previous owner has not had any trouble with the car in such a way before.

I had a quick look underneath and there is a bit of oil residue/seepage near the turbo (Passenger side). I haven't noticed a decrease in boost pressure and engine temps are fine (as far as stocko guages can tell me). From work colleagues who have been car pooling with me at the time and on earlier dates; they say they've noticed it very briefly when driving around but thought it was the vehicles that were in front of us at the time.

The main thing is, my partner's car is in strife and we're due a baby any day now so I want to know what this is so I can rectify it ASAP, so I ask what are possible options for this?

P.S - LONG time reader, first time poster :P

As chook said, check the oil level... but you should know that a common complaint with the VQ25det is that the passenger side bank will leak oil from under the cam cover. It may be leaking and dripping onto the turbo which could explain the smoke. "Simple" solution is to have the gasket under the cam cover replaced.

If the previous owner went nuts with the degreaser, might that actually be what you are smelling?

perhaps some oil leaked out of the oil filter at time of service and dripped down around the gearbox i noticed it a couple of times when i did servicing on my series two, and its the same story a burning smell through the vents and minor smoke from under the bonnet.

So the general consensus is that it is a relatively easy fix?

Where would I go about sourcing a gasket if need be?

Nissan, I think it was around $70 unless that was an imported price. It isnt the same as the 350z so I will have to get the part no. for you.

Not a big job, just be careful with the rear section, its hard to keep the rubber gasket in the groove due to the heater pipes. You will need to remove the top part of the plenum first though.

Cheers iamhe77 - is that for both or just the one bank? I assume just the one bank although I may as well do both while I'm there

Sean

Just the passenger side bank mate.

If the driver's side bank isn't leaking, don't bother replacing it... Reason being that there are built in seals in the cam covers which stop oil from going into the spark plug holes. These seals can break.

So if it ain't broke, don't fix it in this instance :D

If the seal is busted, you will have to buy a new cam cover... and they go for around $300 each :dry:

just did my one the other week had the same smell you speak of!! check with a torch at the rear of the passenger cam seal you will prob see a liitle seepage.. replacing is a little bit of a bitch due to the space you have to work with.. and bit and pieces you need to move.. if you have a uni-joint socket adapter it will be your best friend for removing all the cam cover bolts.. and be sure to be careful not to damage the sparkplug valley seals. (i applied some dirko to one of mine as the spark plug was swimming in oil)

the part cost me $27 from col crawford nissan brookvale 2 days but thats coz it came from WA.

all this is pending thats the problem.. goodluck!!

      My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.

      There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.

      I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.

      Duncan's V37.......race car?

      To re-cap, I bought: https://www.alibaba.com/product-detail/Lsailt-8G-Infiniti-Q50-Q60-2014_1601171829627.html?spm=a2756.trade-list-buyer.0.0.2cd476e9FTIlKE As you can see, if I bought 20 it was $653, but I bought 1 so it was $1,170. I was very tempted to buy 2 and resell 1 at 25% cheaper. @MBS206, I am not sure if they do a Kluger one, here is their list but it might be there under a global model name: http://www.lsailt.com/product/android-interface?page=1 Keep in mind these full android replacements have basically all the bits a phone does (cpu, ram, storage, wifi, bluetooth, usb interfaces) other than a screen (it uses a host), thus the $800+ cost. Android Auto screen mirroring is MUCH cheaper as it's just a cut down shell, input mirroring and output mirroring BTW I also need that "screen off" feature, it is much harder to see wildlife even if a dash is reasonably dark. Both the Fuga and V37 have display off buttons for night use, they just come back on for a second or 3 if you interact with it, eg skip a song.
