creamy stuff build up in breeder pipe

[bajom21]

hello,

i have 96 1.4 golf which is struggling to breed properly. i clean out the breeder pipe every few months due to a build up of creamy stuff??? anyway it stopped on me yestherday but got it going after cleaning pipe.

anybody any suggestions to how it could the build up be happening:1zhelp:

i had the same problem, i don't think you can stop it, it's condensation or something.

I hope someone with more clue helps you out. Mine was cleaned out last year, there was tonnes of it.

A creamy breeder pipe?

Is that a euphemism?

[DropKickMurphy]

i bet you only drive short distances?

it builds up when the engine doesnt get hot enough, it worse in the winter when its generally colder and wetter but if you drive for longer and get the engine nice and warm it is much less troublesome.

it happens mostly on AEE and AEX engine'd cars bacuase of the design of the breather system. it might be worthwhile getting the crankcase ventilation looked at, as if this is getting blocked it will blow grot up the breather pipe and make things worse.

bottom line is its a 'feature' of the engine and there isnt really a cure - just keep treating the symptoms.

Also consider getting a compression test, just to be sure. - this is also a classic symptom of a partially blown head gasket, especially if you see creamy deposits under the oil cap. What happens is that water escapes into the cylinders from the cooling jacket. It often goes hand in hand with overheating too.

Thanks Jon,

I thought it might be head gasket but it never over heats and that why its throwing me off. Could it still be head gasket even if the gauge is only reading normal on temperature.

I took out the airbox because frankly its pants. Sorted out any gunk problem i had, not that i really suffered from that much on mine. The oil seperator is rather rubbish.

I can definately see that helping gunk up the pipe with a nice cold airbox and warm air coming out of the breather. Condensation and oil vapour everywhere. Been gunk free since i sorted it anyway.

thanks sammo,

i will try this method. did you completly remove the airbox. what did you replace it with? new one or did you change it

I fitted an aftermarket filter with some silicone tubing connected to my intake, and made a plenum/heatshield to keep all the nasty NOx etc away from the cabin and to resist heat from the engine bay

I consider that unlikely - every time I have encountered oily cream in an engine it has always been followed by catastrophic head gasket failure. You don't seem to be suffering from this (thank God!), so having read SammoVWT's explanation I think it would be advisable to try his approach first (anyway, he knows more about these engines than me).

If you take apart the airbox you will see where the smaller breather hose plugs in, theres a 'bottle' type of device on top of it.

Im not sure if replacing/cleaning that often will help reduce it but i think thats the first part to get gunk, it then reduces flow and it starts to condense further down the tube.

I think the original idea was to condense the oilvapour and seperate the gas, but i think the emulsification was an unforseen consequence with short journey driving.
