(but not more than 0.9 bar boost) a lot of oil finds its way back through the PCV breather pipe/catch can anto into the intake system, sometimes i get an odd drip coming back out of the HKS filter.(although by the sounds of it not as bad as you). Oil leaks were:(internal one) (the orange one). When it was leaking, I used to collect oil around the mouth of the recirc valve. I assume this is getting into the turbo hardpipe via the PCV where it's then getting very hot, and when hot is thin enough to drip out around the edge of the silicon hose on the turbo outlet, which is done up plenty tight enough!@ Pacific Works has run a compression test on my engine, which came back fine. 11.8-12-12-12 BAR, so one cylinder a little low but within acceptable tolerance. Surely if it were turbo seals or valve stem seals I'd see blue smoke from the exhaust, not oil on the outside of the cold side of the turbo? I think that if I had the recirc disconnected I'd get oil out of it... sounds like the same symptoms to me!- the only club to win 'Best Club Stand' at JAE more than once, and twice in a row! I guess this must be down to reduced intake air temp cause I am not longer reciculating these hot vapours???£15 spent i am well happy. I suppose the downside to this is my oil consumption is going to increase by venting the vapour to atmosphere?.. you've just stopped it manifesting itself in the same way 
That's why it appears as oil rather than vapour with the stock PCV system intact.- the only club to win 'Best Club Stand' at JAE more than once, and twice in a row!(kit from Halfords) revealed approx 9 BAR pressure for each cylinder.- is this appropriate compression? It was in the "green" area of the gauge...."Compression pressure:(11.5 kg f/cm2. 164 psi) or more(9.0 kgf/cm2, 128 psi)(1.0 kg f/cm2, 14 psi) or less(e) If the cylinder compression in one or more cylinders is(a)(c) for cylinders with low compression. If adding oil helps the compression, chances are If pressure stays low, a valve may be sticking or"- I suspect like me as your compression is at the lower end you are getting increased crankcase pressure forcing more oil through the crankcase PCV than norm - ultimately this will find its way back around into the intake and through the combustion cycle again - this results in higher oil consumption and increased intake temperature, the way to go is an alloy catch can with a drain feature so you can reuse the oil - as cheap fix you could put a breather filter straight on the stock plastic catch can - for the cost of just £15 for me this has improved both oil consumption and performance and my whole intake path is now free and clean of oil trail and the ait intake temp will be lower. I noticed improved performance immediately.(as advised) and the results were 10.8 BAR for all 4....
