1. Ive seen several post in social media that 4n15 consume engine oil, about 1 litter per 3000km. Is this normal or not?

2. Too much blow gas or white smoke coming out of the dipstick. As per casa they say its normal because of newer engine design that have EGR. How much blowby is normal?

3. When opening the oil filler cap there is white smoke and oil. I know you dont suppose to do that but is it normal to have white smoke and oil spitting?
