Too much air out muffler

Recently my pro has alot of air flowing out the muffler. It has no color in the day but at night with a car's headlight behind it you can see the whitish smoke.

Also my oil used to remain on the F mark until my next oil change but now it has to be topped up before the 5000km. What causes this "burning of the oil"?

Bro, check your gasket head. I think you need to change or overhaul the whole engine. Correct me if i'm wrong.

Valve stem seals or piston rings worn. If piston rings worn then slight loss of pwr too.
