The oil usage was a bit higher than normal, sience i bought the car, but i use very short trip every day. I go only 2km-s on morning and another 2 km-s on afternoon.(sometime i use it at day, but mostly not)  I never realised smoke from behind, that is why i dont think its valve stem seal.

The bad thing, the car looks and sounds very healty, when its not missfiring.

 

I checked the inlet flaps, when we cleaned the intake. it was looks and turned perfect.

 

The strange thing, all the 5cylinder  intake hoses and valves was equal dirty. Nothing special on cylinder 4.

Maybe the bad things start to happen, when the intake valves closed. I mean if lifter stops working on lower rpm, it can do it.

But cant i hear it, or feel it on idle, or low rpm?
