Nope, I lost it while driving. Could there be a pressure building inside engine, with cold oil ? I have some problems with the thermostat lately. The temperature never goes over 50°C when it's winter time, unless I drive realy slow in the city..

hmmmm sounds odd. you checked the crankcase breather pipes? either way if it's not getting up to temperature change the thermostat. 50 is too low.

Yes I've checked the breather pipe and it is breathing. I will change the thermostat.. Could it be anything else ?
