Since then I have had no problems at all, no loss of oil - nothing. Then last month I noticed oil in my air filter, took it out and it was saturated with cleanish - brown oil, within a week or so the same again. I have since rerouted the breather pipe into a 500ml plastic bottle which is filling up within only a few miles of driving, last night being 500ml in 13 miles.
History of the engine is little, however I bought the vehicle with a broken cambelt and reconditioned the head in my spare time at work, I replaced all valve guides, valves, stem seals, good quality head gasket and the car ran spot on for a couple of months before the first incident.
I posted a thread on here last year when it first happened, back then it was pushing oil into the intake, i put the pipe into a bottle then to keep it from going through. I compression tested it and the I cant remember the exact figures but 1 + 2 were extremely high and 3 + 4 were good, I did the test on my other gti 6 to see, and they all matched the results on cylinders 3 + 4. I cleaned out the breathers and booked the car in for a leakdown and they told me there was nothing out of the ordinary showing
After a few months it stopped completely so I put the breathers back and have not had any oil loss over the last 9 months until a few weeks back, and the problem has returned
I have questioned it being the rings or bores but what has puzzled me is the 9 months of faultless driving in between.
If i could get any other ideas on the problem that would be great
