Hello everyone.

I have a Octavia I, 1.6 with AEE engine.

Had the car for 5 months and been pretty happy with it, despite only having a tiny engine lol

Tonight, the car started firing on only 3 cylinders. She has been using a bit of oil recently (1 litre a month).

I took the air filter cover off, and oil has been coming up the crankcase breather hose into the air filter housing. Coolant is very frothy and a bit of mayonaisse on the oil cap.

Coolant / mayonaisse oil, usually means head gasket failure, but I have never seen oil coming up the crankcase breather hose before. Could there be another explanation, besides head gasket ?

Thanks

The breather box sometimes gets blocked up and will force oil up into the air filter, they always used to put a bit into the airbox tho and mayo on the cap if used for short runs too.

Its not common for the headgasket to go on those motors tho but they do burn a bit oil when the mileage gets up around 80k or so

I will do some more investigating at the weekend.

yup same issue as the akl engines 1.6 8v

My first thought was of crankcase pressurisation. That's normally caused by either a blocked breather vent, or worn bores allowing blowby from the combustion chambers.

Proceed as above to clean the breather system, and if that doesn't work, look at having a compression test done.
