Right just changed my air filter as i wanted to do something with the car !!
I hve noticed though that in the breather hose there is "mayonaise" oil and water mixed up and in the air filter box and on the old air filter itself
Do i take it this is normal because i havent noticed the car going any different !!
any help will be appreciated - hoping this is normal as i cant afford any more repairs !!!
Air Filter - covered in oil ???
Nah the oil caps fine !! theres none on it its just in the air filter breather hose and theres oil in the air filter !! thats the worryng thing why is there oil in aniNfa-ReD wrote:Erm normally if you get that mayo **** on the inside of your oil cap it means a busted head gasket but on a filter i think its fine
air filter ?? i just hope its because the air filter is behind the engine !!
If it helps mine is the 1.4 16v DOHC engine (75bhp version
)cheers
dunno if it should have oil in there, but just got hold of a K&N panel filter and fitted it in mine...the K&N had some oil on...and the new paper filter I took out of mine...(as I had a fluids and filters change less than 2k ago had some oil on as well) so I guess a little has gotta be the norm....either that or the car my K&N came off, my car and your car have all got the same prob.
Mind u mine didnt have any mayo type deposits...

Hello all - I can hopefully shed light on the mayo issue!
Firstly, don't worry, its OK. As other people have mentioned, oil in the crankcase breather hose is OK...but it IS annoying, especially if (like me) you've got a K and N on the engine cos it gets discoloured with bloody engine oil!
I HAVE A SOLUTION...
get thee to a friendly breakers yard. See if you can buy yourself a VW Golf Mk4 oil separator. The reason why you get oil in the hose is because VW's stock oil separator is quite frankly hopeless.
Plumb the Golf separator in (easy but awkward because its on the back of the engine) and this will clean things up.
Hope this helps!

Funny that, I fitted a MK 2 golf oil seperator! Great minds think alike.
Yeah, the moisture from the oil gets mixed with the oil vapour mist and you get ski yoghurt in your breather pipe.
The Polo engines all have lots of oil mist, from being brand new, its nothing to worry about and is caused by the upper cylinder lubrication. Basically, there is a controlled amount of blow-by as gasses are exhanged for oil in the honing pattern, by the control ring.
But the downside is that your oil gets a battering and actually toasted oil gets blown into the crankcase.
I have looked into this a lot, and concluded that its not a problem, provided you understand it. It can screw up the ECU and gum up the throttle body, requiring you to readapt your ECU.
The best way to aleviate the problem I found was to increase the frequency of oil changes, particularly over winter.
Say Change Nov, Feb and July. And use only the correct oil from VW.
-The last point is important. Not all oils of a certain spec are created equal. As mentioned before, the intense pressure and temperatures that occur with this engine design causes some oils to breakdown, which is why you must use a fully synthetic oil, also problems with sticking valves etc, caused Ford and VW to make their own engine specific oils. You'd think that something like magnatec would be best for your engine - but in fact you'd be wrong.
Best thing to do is to change it at least twice as often as recommended.
