    Default funny coloured oil!



    do I have a problem?

    Just checking my oil/fluid levels today and noticed the coolant was about 1cm below the cold level (may have been here for ages - have not looked at it since I had the car in for its gearbox probs a few months back)

    Im planning to change my oil soon as its been in for 15K (it should be the long life stuff but who knows with dealers!)

    I checked the oil level- ok (have not checked this for about 5k!!)

    I took the oil filler cap off (have not done this for about 5K!) and there was a very light brown oil residue under the cap and a bit in the neck!!!! - this normally means water in oil??. I should have taken a pic of it but I wiped it clean before thinking

    Im going to moniter this but any ideas??

    if you only do short journey,s then it might only be emusified oil, due to the engine not getting hot enough long enough,
    my vectra b used to emulify, but it would dissapear when i went on a long journey, allso some oils tend to emulify more than others, let,s hope it is not the head gasket "eh"
    ed
    ps i have noticed it on my filler cap on my 3.2 vectra, i have not been on a good run in it for a while either.

    I be waiting outside a Vx garage for them to open if I saw that under my fuel filler cap.

    Get it checked mate.

    Ed - my normal commute is about 12 miles of fast dual carriageway - so I thought that would be long enough to warm up even in this bitter weather!

    AJA - yep that is what I was thinking - never seen that on any of the cars I have owned!

    going to keep a close eye on this!

    Never heard of this on a C or Signum before, but generally it is not an issue to worry about.
    If it is only a thin light layer it is most likely caused by condensation, which is not evaporated if the engine does not get hot enough, can be more of an issue if you do lots of short journeys, even more so at this time of year.
    If you have it on the dip stick then it's time to get it checked out and if it's in the coolant expansion tank then it's time to worry.
    Might be worth checking with a dealer but not a lot of point if you've cleaned all the evidence up.

    Yep - doh silly me!

    dipstick fine and coolant looking fine

    Car had been sitting in the cold garage all weekend so may be condensation related
    fingers crossed!

    My 3.2 suffers as well..My mate at VX said that it was just normal as the oil filler neck is extended further from the camcase than on the x25xe and x30xe.
    This means that any oil mist has more of a chance to condense with water vapour as it's further away from the heat source of the engine..

    He's been with VX technical for 25yrs so i kind of believe him..

    If the coolant loss persist's I'd be back to the dealer thou, particulary after the auto box coler incident..

    Just checked it today and it looks kind of scary - but as you say Mark - it’s only round the actual filler tube - no sign of anything in the engine itself!!

    No more coolant loss - but going to keep checking it!

    Does anyone else with the 3.2 suffer from this phenomenon?

    hi iborob17... that looks exactly like my oil filler cap... that is emulsifyed oil, due to condensation.. i am prity sure it is nothing to worry about, unless i am very much mistaken i am not worrying about mine. it was a lot worse on my vectra "b". the wife has the car now and it still goes ok.. i do put mobil one in it i always have, i seriously dont think we have a problem. look at the thread "panic" it seems to be a 3.2 v6 thing... i wonder if this weather has someting to do with it.
    maybe to put some of that foam tubing stuff that plumers put round pipes might keep the cold air out. unless the filler pipe gets very hot as it might melt the foam, just an idea, i might try it .
