Why is there oil in the spark plug well?
2003 Nissan Altima, 3.5, 110,000 miles.
Went to change the spark plugs after obd2 read a misfire in cylinder six, when i removed the ignition coil it was soaked in oil, as well as the spark plug when i removed it.I Wiped out most the oil and finished replacing the plugs. After starting it the first time white smoke was pouring out the exhaust for a min or so and stopped,and the car drove fine.
However today i started it up and it was misfiring again, worse than before and this time the check engine light kept flashing all the way home, p0306, cylinder six misfire. What could be causing oil to get in the spark plug well? Im assuming the oil is causing the misfire.
