    Creamy oil - X16SZR

    Hi folks.

    My 1.6 8v single point injection engine keeps on making small amounts of white cream on the oil cap. That normally points to head gasket issues, but coolant levels have been consistant for 6 months.

    Am I right in thinking it could be the oil cap? The cream gets worse in wet weather, and then reduces in dry weather.

    A friend's '02 1.6 8v multipoint injection does the same thing, as does the 1.4 8v Corsa company car.

    try just giving the engine an oil service and put some oil cleaner aditive in the oil first, while your at it why not do the same sort of thing to the water system

    It could be condensation on the inside of the head maybe? I had this problem on my old MK3 astra with the C14SE engine, it was tested etc & found no problem with head gasket & put it down to condensation inside the head

    The oil has been changed 3 times since I got the car. It was changed by a local mechanic when I got the car (Network Q didn't service it worth a damn), once at 38k, and just a month or so ago at 46k.

    Coolant was changed at 46k along with timing belt etc too.

    It's definately something to do with weather conditions, as cream production goes into overdrive during wet weather, and goes away to nothing during dry. I normally clean the gunk off with a paper towel weekly - on really wet weeks the gunk can literally fill the whole gap between the cap and the baffle!

    i dont know if it will help but i saw an additive that you put in your fuel tank, its supposed to stop condensation in the fuel tank and engine etc, its made by wynns i think.

    i saw it in my local motorparts direct

    Hmm...I doubt there's condensation in the fuel tank, as it gets necked at least twice a week (32mpg makes trips to Tescos regular). I do fairly long runs, so I'd have expected condensation to evaporate fairly quickly...

    Still, thanks for the suggestions - more appreciated.

    Is this a common issue with these engines?

    It's a water/oil emulsion caused by water in the oil.

    I would wager that you use your car for short journeys.

    In cold, damp weather condenstation forms in the engine after being run for a while and then switched off. When next started the water should warm up, turn to steam and be vented via the breather. However if you only do short runs, the condensation never gets fully 'burnt off' and so recondenses when the engine stops, and more water condenses from the atmosphere.

    Eventually you'll end up with this mayonaise crap all over the inside of the rocker cover, and it usually bungs up the breather to compound the problem even more.

    Simple cure - check breather for blockages and remove any found.
    Remove rocker cover and clean all crap out, drain oil and refill.
    to prevent reoccurance have regular days out including a long drive to boil all water off.

    Does the cap sesal properly?

    Its not much to worry about, if its on the dipstick then worry!

    You could pop the cam box lid off and have a peek to see if there is anymore inside.... but i doubt it....

    I've got a new rocker cover seal and a new cap ordered, so I'm going to pull the rocker cover next weekend. I'll change the oil and filter when I'm at it too.

    That should sort it mate - just remember to give it some long runs every now and again to boil off the condensation.
