    Default Smoke and sludge from oil filler cap Vectra C 3.2 V6

    Hi all,

    I have been beavering away on the "c" and other than changing the oil (because I can't get the effing sump plug out) and today i was checking a tick tick tick noise coming from the the valley cover area (sounds like the throttle butterfly's are hitting the top of the cover) and I took the oil filler cap off and geez it was white, milky and sludgy..... and little puffs of white smoke coming out the filler hole. So I took the dipstick out, the oil colour was not milky, but little puffs of white smoke as well..... next I looked at the egr pipe leading to the MAF and ta da.... more puffs of smoke and a fair bit of white sludge... my first reaction was to see how low or high the coolant levels were, and they haven't moved, still spot on. Could someone tell me that the engine is going to be fine and all I need to do is to put some desludging fluid and new oil through it, when I manage to get the bleeding sump plug out.

    Cheers in advance

    Greg

    As too the emulisied oil in the filler neck. That is commen on the 3.2V6 if you do short journy,s./ I removed the filler tube and put the filler cap back in the place of the filler tube. No more emulsified oil. The emulsifed oil is due to condensation forming in the filler tube as the engine has not got hot enough to "burn" it off.

    Ed,

    Thanks for that, will do it in the morning.... as for the puffs of smoke, does the car have something up with the compression or will it disappear when the engine is warmer. The tick tick noise from the top end is a bit of a worry. I had the silver cover off yesterday to clean the sludge out of the MAF and the inlet manifold was also full of oil crud that I cleaned out. I made a "catch tank" out of a 600ml coke bottle and routed the hose into the end and a spare bit of heater hose from the base to the MAF and holy dooley it filled with white smoke (a bit whiffy too - like burnt oil) and in one days driving of about 70 kms it had about a teaspoon of browny oil sludge - that must have been going through the MAF and inlet, no wonder it was running like a pig. SO the problem(s ) are: white puffs of smoke from the oil filler, a tick tick tick from the inlet manifold area and a sump plug that had been put in by superman. Any help would be greatly appreciated.....

    Cheers in advance

    Greg

    Are there any breather pipes that could be choked with "gunge" thus forcing the gas back to the top of the engine. Sounds a bit like crankcase gass,s might be getting to the top of the engine. Or at least not getting burn off if they do.
    The sump plug. But a new one before you knock the old one about.
    Try using a "cold chisiel" and tap it undone. Maybe some mole grips might fit on and remove the sump plug.

    Ed,

    Sounds feasible. Where is the EGR on the V6? I might start there and work my through all of the pipes and soak them in degreaser for a while.

    Cheers

    Good point. I am not sure where it is situated. Hopefully another member will be able to help there.

    What made a huge difference to mine at its last service/mot was i paid for an engine flush and then an additive with the fresh oil. The oil looks very healthy and i believe the car was running slightly better.

    Might be worth taking it to a garage for a cheap oil and filter change and paying for a flush.
