    2014 Jaguar XF 2.2 - Suspected bad turbo seals

    Hi Guys,

    Recently my car has been leaking oil from one of the turbo pipes that attaches to the Intercooler.

    Car is a 2014 XF 2.2 D.

    So I went about investigating the leak and it was coming from 'A' as marked in the image below. Initially I suspected something was loose? So I tightened
    one of the bolts at the bottom of the fixture and cleaned everything. However I checked after 2 days and I found some oil was again there. Just to confirm this is
    engine oil and not coolant etc.

    Since the car is under used car warranty I called the dealership and asked them to get it looked at it sooner that latter. However being my luck the appointment date is
    03.12.2019 and this is without a courtesy car. So I am stuck now as they can't book me in. They have asked me to drop the car off with them and hope for it to be looked at
    sooner if there were any cancellation.

    In the meantime, the service department asked me to call the Jaguar breakdown service technician to make sure it wasn't anything serious. So out they came and it turns out
    the technician (AA) was confused as to why there was oil in the intercooler / turbo pipes? To which he suggested it is suspected case of Turbo seals going and hence leaking oil into the pipes. Just to add I have been checking the oil levels and it still shows as full.

    Now before I go about panicking further I want to ask should there be oil in 'A' as per image? Also to add I found oil in 'B' which is the crank case breather pipe that attaches to the CAI.

    If it is the seals gone then I want to add that I am not experiencing any symptoms:
    - Loss of power
    - Loss of oil
    - Limp mode
    - Engine sound weird
    - No error codes
    - No white smoke

    When I ask for power from the car it delivers without an hesitation.

    My question what I have explained above, does it sound like a bad turbo seal?
    Also are we supposed to have oil in A and B?

    I can't see your pic I'm afraid.
    If the turbo is leaking a small amount of oil from the bearings supply to the intake side then I imagine you may not see any loss as such (if it's only a small seep) and if it's not getting through the intercooler it's not reaching the intake yet - hence no smoke and more importantly, no damage to the DPF. Given that, in all likelihood, you wouldn't get any warnings. How did you spot it in the first place? As it's sealed system, if it were minor I imagine many of us could have this issue and never know.
    Will still need to be checked thoroughly and possibly a new turbo.

    Spotted the leak when had the car sitting for 5 days. It had started leaking from the driver side from on the intercooler pipe that attaches to the intercooler. There are 2 bolts holding this pipe and it was leaking from the bottom. The technician did say it was unusual to find oil in that area and specially the pipes connected to the turbo directly.

    hmm - well with many of these things, it all swings on what is normal. Doesn't sound right but you really need someone who takes these to pieces regularly to say how much oil should be there, if any.

    It's like the front arms on my XF. A garage refused to do an alignment check because they were insistent that the bushes were shot. They even demonstrated the front wheel moving slightly back and forth. Took it back to the dealer (was under warranty) for a full check and they said it was absolutely fine. Nissan Primeras used to fail MOTs on the rear (multilink) suspension. Too much play. Nothing wrong with them, they were like that from new.

    So you need a specialist to either declare your turbo faulty or put your mind at rest.

    Apologies in advance here as I'm not clued up at all, but this sounds familiar. I recently had a service done at my local independent garage where they found "oil leak on intake side of turbo/.../oil in boost pipes/.../small amount in boost hoses/.../slight play on turbo shaft/.../suspect oil starting to slip past seal."

    These are their notes and I think after further inspection they weren't massively concerned right now but did suggest it was something we needed to keep an eye on. As I'm not remotely qualified to know what to look for I've been looking around for something similar and this thread was the closest I've found.

    Any update on your problem and anyone care to feedback on the above?

    Edit: XF, 2.2l, 62 plate.
