A few years ago a woman brought in a car because it was smoking like crazy and smelled really bad. She told me her husband worked swing shift and after work in the middle of the night, he changed the oil, but was surprised it took so much oil. He kept checking the dipstick and put in 8 quarts but still couldn't see the oil on the dipstick. She was sure this indicated something seriously wrong with the motor. So she brought it to me. The air filter was soaked with oil that came in through the PCV system, this oil was being pulled in the intake air and was burning and causing a lot of smoke out the tailpipe. I dropped the oil and found about 13 quarts of oil in the motor! Apparently he had forgotten to drain the oil first. So i just put back in 5 quarts and a new air filter after cleaning the air filter box and intake tube as best I could, and ran the car for a bit. No more smoking and everything fine. The woman was pissed at me saying I was a rip-off, she knew she didn't need a new air filter because it was replaced a couple months ago, I was a crook and a liar. She paid me the $35 I charged and drove off. So yeah, can get smoke from putting in too much oil, but it usually has to be a lot.
