What is your question?
Car runs good but had lights come on O2 sensors, both have been replaced, Car has had all injectors replaced, all new spark plugs, whole new exhaust system, new pcv valve. As I said car runs good but after a little while even after warm up when you take off get big puff of smoke when you take off, then smokes periodcally. Doesn't leak oil that I can see, put cardboard under had no oil spots. I replaced the oil filler cap because oil was spraying out of it, new cap stopped that but seems to have a lot of pressure on the oil. No oil in radiator and no water in the oil. Just don't get the smoke all of a sudden well after warm up.
How long has your 2006 Nissan Sentra had this problem?
More than a month

Hi, smoke that is white indicates internal engine coolant consumption or excessive condensation has built up in the exhaust. Blue smoke would be oil burning. Black smoke is more carbon based, such as fuel or fuel too air mixture issues. Get with a pro at a shop near you for guidance!
