Mechanic in the army for 12 years. Changed the oil. Made sure the pan nut was on tight, oil filter is tight, replaced 5 quarts with oil filter. No problems. I started car and white smoke poured out of the exhaust pipe and it has the smell of burning oil. Under the hood I believe it is the oil pressure sending unit. To the right of the valve cover. Have let it cool off and tried it again. One thing was weird when it started for the first time, it sounded like the timing was off or I was down a cylinder or something but then smoothed out.

any ideas?

How long you owned car? What happened last oil change? What was the oil like you took out? What did you put in? Did you overfill it? What does oil sender have to do with it?

5 years. Just paid it off, I have always changed the oil every 3-4k. No difference in the look or smell of the oil. Same oil as usual 10w-30. I put in 5 quarts as usual. I added the sending unit because it had a little smoike coming from it. Weird huh. Coolant level is normal and not falling. It smells like burning oil. No leaks under the hood. Or engine. (Spilled oil I mean). I would never ask this question if I had not just changed the oil. I know white smoke usually means coolant in the system. Kinda confused on this one lol. Car has never overheated or anything.
