Rite today when fitting my bulbs i checked over the oil water etc and then opened the oil cap, with a load of mayo crap in there, i dont know if its HG or not (pray to god it isnt).
well im not loosing any oil or water, and dont use my car much, when i do its not much. my dad seems to think it maybe cause i put redex in a while ago, i seem to think its the lack of use, cars preforming fine, no problems that im aware of, would there be any other symptoms of HG or is it lack of use?

Cheers:yes:

i hope so, if its just sat on the road for a few days would that cause some? or would i need to do little trips for it to appear?

Have a look at the dipstick,if there's no mayo on it the headgasket should be fine. If you take the car for a good long/hard (ish) drive,it should clear up?

This is a good read....I wouldn't worry about your headgasket,as your car isn't losing coolant/overheating!






The stuff under the oil cap (AKA mayonnaise) is an oil/water emulsion - they can and will mix given the right circumstances.

Here's some science...

When you switch off your engine in weather like we've had recently, ie cold & damp, condensation will from inside the cooling engine. When you start it up next day the condensation gets thrown around with the oil and the churning action of the engine causes the oil and water to form this emulsion over time.

However given a long enough journey the water is normally boiled out by the heat of the engine, but if the journey is not long enough the water can't boil away, and when you switch then engine off again more condensation will form, compounding the problem.

And this goes on and on, increasing the deposit inside. As it's not too runny compared with the oil it usually gets stuck to in side of the cam cover - which is what you've got.

Changing the oil will help, but they'll be plenty more inside the cam cover to redistribute over the oil cap.

To cure - remove cam cover and clean all the deposited crud out of the cam area.
Clean the engine with engine flush.
Replace oil and filter.
Go for a long drive to boil out any remaining oil.

The only way to stop it coming back is to make sure that every so often you go far a decent long drive and or change you oil more regularly than recommended by VX. You should be OK once the weather gets warmer/drier

it's literally just condensation, 6 miles a day has caused mine to clog up big time. take it for a drive for 20 miles not using 4th / 5th gear at 60 soon clears it.
