Hello everybody!
I got a problem, was driving in normal conditions (well it was suddenly -7, actually) and got -1.5 L oil on the display. I opened the boot and it was all covered in oil. I had to fill 4 liters to get back to normal.
I do understand it is something to do with crankcase breather, but I can't really find it. There is no direct description of this problem on fantastic Lofty's pages, which I studied a lot.

It seems like it is somewhere on this pic

Can you suggest what and where should be cleaned to avoid such problems in the future?
P.S. I own A-140 (1999-160,000 km) for 4 years, changed both chains, lock on left back door, plastic gearshift thing, front breakdiscs etc.
