    Default 4th Swirl: Covered in Oil 1.9CDTI 150

    Hey Folks,

    VX replaced my egr a few weeks back after me complaining about:

    "Juddering on startup, with grey smoke emitted from exhaust, combined with poor fuel consumption, and poor perforamnce below 2k"

    However the issue has pretty much returned. Took the cover off tonight to have a look, and theres a definate patch of black oily crap building up around the 4th swirl valve (Far Right). The bar is still attached, but this 4th swirl looks in real bad condition compared to the other 3 which are there.

    I spotted this a few weeks back, but the oily patch wasnt as bad then, but is defiantely worse now.

    Im getting it booked back i again, but this develeopment combined with the smokey/juddery startups would seem to suggest either injector issue or inlet manifold issue would it not?

    Thanks for your help

    Crap i thought it might be.

    I think this is the main reason for the start of the reduced fuel consumption.
    Thank God it's under warranty still.

    I'm a bit peeved as they have done the EGR, but vauxhall being vauxhall they must have purposely left inspecting the inlet out of the equation.

    What's more annoying is the fact that the "laptop says no" when it comes to the manifold, as it generally doesnt produce any fault codes

    If the car is in or just out of warranty try vx.....escpecially as they may at least pay half the cost should the car have a healthy service history with them....if you are out of the warranty period.

    As the guys said before this is the start, the flaps can move up and down allowing the greasy/sooty stuff you spray outside of the manifold. The car may drive without limp mode but the performance will take a dip.

    Hope you get it sorted though.

    The car is still under VX warranty, so I expect them to cough up in full, as I will refuse to pay a single penny. Obviously a crap design with the older inlets hence the modified version to prevent the same problem.

    Car also has full VX service history, and ill be continuing to service it there so long as I have the vehicle, purely becuase of these reasons.

    That would make sense about the top end of the rod lifting letting the crap through. I take it the 4th swirl valve is essentially sticking compared to the other 3 in that case?

    It's annoying becuase it is a cracking engine, just so sodding fragile

    Just taken delivery of mine yeaterday and noticed relatively poor fuel economy (42 MPG on motorway at 70) which around the same as I got on my 1.8petrol this obviously started the alarm bells ringing so after taking the cover off I have noticed exactly same as described, 1,2,3 all ok but 4 with what looks like lithium or graphite grease seeping from around sides (see pics). I assume this is the start of the dreaded inlet manf failure. car is a 56 plate with 32.5K on the clock. Images are in order cylinder 1, cylinders 2 + 3 and the last two show cylinder 4 with different lighting.
