Hi there,

Thanks for the above......fitted the linked unit and it fits a treat. Only 1 small problem......
I have a weep of oil from the elbow that bolts onto intercooler. I re-used the old gasket so I am guessing that is the problem. Any links the the gasket.....or should I be using some liquid gasket?

Thanks for all your help,
Euan

Which shows the "problem" hasnt been cured, just masked ;-)

But most already know I rant on about changing the airfilter regularly virtually cures the leaky intercooler problems :whistle:

I had oil all over one side of the fins....pretty sure I needed a new intercooler. Just need a new gasket since I had to change the elbow.

Intercoolers arnt designed to hold oil, mine was leaky as anything, everytime you pulled up all you got was the lovely smell of burning oil off the turbo heat shields and turbo as it dripped off the corners, like many I was going to spend £100 or so on a welded one but then after doing some further digging decided the problem was more that the induction system was poor and I feel the airfilter just isnt big enough and gets bunged up far too quickly causing the engine to suck far too much oil vapour into the induction system than it should, thus by keeping the air cleaner nice and clean the problem goes away.

I took it off, cleaned it out a bit, changed the airfilter twice now in one year and Voilà leaky intercooler is now much improved almost totally stopped leaking now, cos theres no oil getting sucked into it :thumbs:
Folks change intercoolers and fit catch cans etc which IMHO isnt needed as long as you change the air filter regularly.

Its one of my things I bang on about here, folks get use to me :lol:

Same happened when I changed ours. Just remove it again and put a thin smear of instant gasket (or similar) on each side of the original gasket and nip it up again. (Or buy another gasket and torque to whatever Nissan recommend). Generally, flanged joints with a small number of bolts (like this one) tend to bow if OVER-tightened, and yet that is usually the first reaction when anyone spots a leak. Usually it just makes things worse!

Hi everyone

Ive been reading this thread with great interests as I too am having problems with my 2005 2.2 dci xtrail.

When I lift the bonnet i can see oil covering some of the pipes and covering the engine directly underneath the silver square thing (as you can now tell I know nothing about car engines).

The thing is everytime I check the oil, the indicator shows no sign of the oil being low so I suspect its nothing to much to worry about going off what I have read. The trouble is I have seen a difference in performance. The car used to be pretty nippy for its size but seems to struggle to get to 70mph. It still does it pretty quickly (though not as quick as it used too) but you hear the engine revving harder. Whilst doing so there is also a large amount of black smoke billowing out the exhaust. To be honest the black smoke happens when you accelerate going from 2 to 3 gear and only subsides when your maintaining speed.

I loaded it full of camping equipment the other weekend and took it out. Same problems occurred but I noticed if I came to a hill the car really struggled maintaining its speed up the bank. This could be because of the weight in the car but I was shocked at how bad it was (with black smoke eluding the road behind me).

Anyone got any suggestions as to what it might be. Car is due a service but all this surely can't be down to a dirty air filter.

Thanks in advance

Black smoke is unburned fuel. Either injectors, or perhaps an airleak in the induction. Check for boost leaks - our EGR cooler pipe went recently and had a similar effect.

I have recently purchased an X trail 2.2 SVE with an oil leak and the exact same whining noise as posted previous. Mechanic thought it was a seal on driveshaft, replaced it and the leak is still there and also the whining noise. The oil is hitting the floor in the center just behind the front wheels. Are the two symptoms connected?

Hi Joe,

cannot believe what you have typed in, it describes the symptoms on my 2004 2.2 SVE exactly.My oil is clear hitting the floor in the same place and running along the sub-frame onto the exhaust. Suspect mine is from a leaking trans-axle seal but have no confirmation as my main dealer turned me away and didn't want the work! My noise is more of of a bird chirping sound but any guidance from those in the know would be appreciated.

Yes, same here Pridenfall, the oil smells strong and its clear oil. I get the feeling mechanic doesn't want to do anything with it, but why? Would rather have an honest answer than be left in the dark.

Hi Joe

I think we are in a trap. The current value of my vehicle in average condition is quoted as £2,500. This gives main dealers no scope for working on the vehicle.Their hourly rate for taking out the engine to work on it quickly exceeds the vehicles value.

In my case I bought a low mileage vehicle thinking I would have trouble free motoring, HuH!. Thanks to the experts on this site I have replaced failing front/rear drop links, leaking intercooler because the weak turbo is probably failing, a rattling timing chain needs new tensioner/guides and now a transmission oil leak is ruining my drive.
I believe our only way out is to find a Nissan specialist who can solve all the problems in one go, however we will still face a large bill and significant time off the road.

Hi Joe,
subsequent to my previous post I have now found an engineer in the Midlands willing to take on a rebuild. As suspected the rebuild estimate comes to the estimated value of the vehicle. Decision is: a. scrap it and stop my losses or b.take the philanthropic route and end up with a reliable vehicle which it should have been when it was first built.

Regards

Graham

Hi Graham,
Well I have just towed a livestock trailer 72 miles down the motorway and the x trail was perfect, I was beginning to think maybe I have been jumping the gun a bit. Pffft. No I was right all along. Set off back and no, she had , had enough. After going into limp mode, black smoke and gears crunching we slowly made it home with no power. Still got the whining noise and oil leak. Another mechanic is having a look on Monday, but if things are bad I'm afraid I will be giving up. Let me know how you get on with yours Graham.

Regards Joe

Hi Joe,
sorry to read about your problems. I always assumed that our problems were transmission related as our oil leaks are clear oil. However, if you were in limp mode and throwing out black smoke thats a different matter. Past experience has told me that an air leak in the air intake can be a cause. I have also read on this site that it can be an SCV (suction control valve) which is part of the fuel pump.Not sure if you are a DIYer but apparently its possible to change you own if you search for instructions. There are also tips on how to get out of limp mode i.e. by switching the engine off and on again!

As for my XT I'm parking it over a drip tray, and changing my oil to 5/50 as recommended elsewhere.Might as well accumulate a few more miles as it runs fine usually. Mot is due in a fortnight so I'll get it through that first. Contemplating changing the turbo myself (10 hours apparently) to cut down any future garage time.

Best of luck Monday,

Regards

Graham

Hi Joe,

further to our oil leaks, lay under my engine bay today and found two oil leaks. Dark oil leak which I thought may be coming from the oil filter is in fact due to a leaking crankshaft oil seal. The clear oil leak ,which we have both suffered, in my case is due to a leaking right hand drive shaft oil seal so it is gearbox oil on the floor. No easy way out.

Regards

Graham

Hi all,

Have just had a new (refurbished) turbo and new intercooler fitted to my '06 XT Aventura with 135k miles. Symptoms were oil coming out of cracks in the intercooler and very smokey exhaust. Cost was around £1,125 at a local garage in Northampton. The main dealer who originally diagnosed the problem wanted around £2,500 - although that was for a new turbo. So far so good after a couple of hundred miles. Worth saying I've had the car for six years now and bought it with only 30k miles. As I'm planning on keeping it for a good while yet, I've booked it in for the full rustbuster treatment in Spalding next month.

Cheers,

Phil (my first post)

Hello,
Sorry to hijack this thread...
Can I just ask if anyone has bought a new intercooler recently - 2005 2.2dCi - they seem to be about £100-150 on eBay - but I would prefer a recommendation if possible.
Thank you for your time, kind regards, John
