    Default blanked egr but swirl bar looking oily again

    I blanked off my egr (on the exhaust manifold side)about 2 years ago after having a new inlet manifold.
    But i have noticed that there is quite alot of oil and crap build uo around the swirl bar/pots again. is this supposed to happen?
    i thought blanking eliminated it?

    Blanking the EGR will only stop the soot, but this mixing with the oil is what causes all the issues.
    The oil is most likely from your engine breather setup, it's not very good at separating the oil mist on these engines and gets into the inlet pipework. You may find that your throttle body fills up with oil and packs up so it's worth stripping this down to clean it.

    The oil in the inlet manifold shouldn't actually cause any problems and may actually help to lubricate the swirl flaps where they come through the manifold, but I know what you mean about it being a mess.
    Some members have fitted oil catch tanks to reduce this so do a search for those threads.

    If the oil is excessive as in blue smoke from the exhaust sort of quantities, then your turbo seals are suspect and if this is the case, you really need to get the turbo looked at ASAP before the engine runs away (runs on engine oil).
