Re: Oil on the air filter and Oil Separator Leaks (T31 Diesel)


Really sorry to hear the issues you have had. I guess you won't be buying another Xtrail (diesel or petrol) again.

Can you list briefly in point form the problems you have had and what was done under warranty. We may have a few items in common to send a communique to Nissan with an ultimatum to rectify whether in or out of warranty.

Re: Oil on the air filter and Oil Separator Leaks (T31 Diesel)


i had to check if it's ok to post up.

1000kms September 2011 - First service, mechanic noticed oil weeping around engine, and undercarriage tray is damp. Dealer says it's normal, nothing to be concerned about. Oil + filter changed.

3000kms October 2011 - air filter has smudges and airbox aseembly is damp with oil. Provent fitted, Boost gauge fitted.

5000kms December 2011 - Undercarriage tray is wet. Engine is weeping everywhere. Hard to see the source. Oil is changed. Dealer washes down engine bay to "determine source of leak" as it's hard to see.

10,000 kms May2011 - Dripping oil heavily everywhere. Undercarriage tray is soaked. Engine appears to be leaking oil everywhere, oil seals, turbo lines etc.. source hard to find. OIl is changed. Car is taken to dealer who washes down engine bay and asks me to bring the car back.

11,000kms June 2011 - On the eve of the move from WA to VIC, dealer finds the oil leak. Engine needs to be pulled out. Takes 2 weeks as they required more parts they got deeper into the job. Not sure what's been done except front seal, sump seal, rear main, drive shaft etc etc... (first time engine out). oil is changed. car is returned going into limp mode within 10 minutes, and after numerous resets, it is fine after 2 hours. first and second gear do not engage / disengage properly when cold.

13,500 kms - Oil warning light comes on in Adelaide. Dealer had given me a full bottle of oil. 2.5 liters goes in.

15,000kms - Oil warning light comes on arriving into Melbourne. Rest of oil goes in. Car goes to dealer the next day, to have engine pulled out and all oil seals replaced (2nd time engine out). oil is replaced.

16,800kms - Oil still leaking onto ground, just as bad as before. Dealer is initially unable to spot the leak so car is left there for 10 days. In this time they pulled apart the gearbox, initially suspecting oil pan, then rear main, then discover the flywheel bolts are leaking. Car is returned 7mm, 8mm, 4mm, 3mm out of alignment, wires are not connected properly (no spot lights and stereo). also boost level is now peak 26psi as opposed to 31 psi. Also intermittent traction control and abs lights on.

 I did casually mention to the technician that the engine cannot handle more than 25psi (info from a reliable source) so maybe he adjusted it? at my expense, alignment fixed at, wires sorted. oil changed anyway as it looked awful.

Re:


also forgot to mention, provent has been disconnected at the last visit to the dealer. Apparently it is normal to have oil on air filter, this happens in bmw, merc, vw etc.. provent being non factory cannot be there for warranty.

car is now "fixed".

also, there are further problems and drama which i cannot disclose...

Re: Re:


I guess from the seriousness of the issues and the bits you cannot disclose, Nissan are involved in some sort of redress. I know they have fixed items under warranty but given the nature of these problems at such an early stage and low kms, it would suggest a replacment vehicle is in order.

I am interested to know they can program the boost - what is the factory default setting?

Re:


Regarding Nissan - they will uphold their warranty no worries, and will keep fixing the issues until it stops. However, at this stage, the expenses to fix the problems have exceeded the cost of the replacement engine, and the replacement engine is 16,000 dollars bare, no manifold, turbo etc etc, just the engine itself. If it leaks oil again, and the engine needs to be pulled out, the cost of repair will have exceeded the value of the car (dealer values the car now at 20,000 dollars).

regarding boost - there is a difference in boost levels between auto and manual, hence the horsepower difference. Maximum boost the engine can take is 25psi give or take. my xtrail is peaking at 26 - 27psi, which is slightly on the high side but still within specification. Unfortunately, i can only get the peak boost information, and of course nobody will simply disclose how to adjust it, though i am partially convinced it involves the ECU.

Re: Oil on the air filter and Oil Separator Leaks (T31 Diesel)


I installed the Provent 200 about 2 weeks ago after finding that my air filter had been sprayed with oil.
ImageImage

After 2 weeks the filter in the Provent is pretty much black and I have approx 0.5cm of oil collected in the drain hose. Hard to believe all this was being pumped into the air intake.
ImageImage

I emailed the Western Filters who supplied me with the Provent 200 kit to ask if this was all normal.

Hi, I bought a Provent 200 from you roughly 2 weeks ago. I was just wondering how much oil would you expect to capture/filter in that time for a 2L diesel? The filter is pretty much black and the drain hose has a probably 0.5cm of oil in the bottom. It's definitely doing it's job but I was just wondering is this normal? I can't see the filter lasting too long if that much oil is being sprayed on it. Regards, Todd

Their reply:
That is definatly normal. The filter should last 20 – 40 thousand k’s Thanks & Regards Western Filters

So looks like the Provent 200 is doing it's job. I would definitely advise anyone with a diesel to get one.

Re: Oil on the air filter and Oil Separator Leaks (T31 Diesel)


Heres my install on 2011 T31 TL ....

Provent 200 kit :

I noticed everyone installing them really high up which isn't a problem at all... but i thought id have a go at getting a more flush fitment . It wasn't real easy but it looks factory i just have to paint the mounts black . Everything fits in without rubbing or touching anything. I have a drain fitted under the car for quick easy draining.

I used the proper fuel / oil rated hosing , stainless clamps and brass elbows .

To make the brackets : 20mm x 3mm thick aluminium ( there extra rigid )

Looks good. Nice job on the install. Your engine bay is just a smidge less muddy than mine too emoticon
Image

I have since changed the bracket to look more like yours but up a little higher. I used 3mm aluminium too. I couldn't install the drain hose and tap to under the engine as my bash plate was in the way. U can see the temporary solution in my picture of wrapping the drain hose up and over. Still trying to figure out where is the best place to send it permanently.

Keep us updated on how yours works and how much oil you collect.

Re:


At the start of the trip yesterday I was amazed at the oil sitting in Todd's drain hose.
By the end of the trip some 5 hours later, the oil had doubled and I could not believe how much oil filled into the drain hose in that short amount of time.
