I HAVE A 1999 SENTRA AND I NOTICED I HAVE OILY SPARK PLUGS! I RECENTLY GOT AN OIL CHANGE 3 WEEKS AGO! THE FIRST THING I DID WHEN I NOTICED THE OILY SPARK PLUS, WAS CHECK MY OIL LEVEL! IT WAS WAY PASSED THE HIGH LEVEL, ALMOST A HALF INCH! WITH THE CAR COLD! DO YOU THINK THAT COULD BE A REASON WHY THE PLUGS WERE A LITTLE OILY? ALSO, I HAVE NO WHITE OR BLACK SMOKE COMING OUT OF MY TAIL PIPE. I SMELLED THE TAIL PIPE TO SEE IF IT SMELLED LIKE BURNING OIL! I ONLY SMELLED GAS. I CHECK UNDER THE OIL CAP FOR WHITE DEPOSIT, TO SEE IF ANY ANTI FREEZE IS MIXING WITH OIL, IT IS CLEAN. PLEASE HELP HERE! IS IT BECAUSE THEY FLOODED MY ENGINE WITH OIL?

THANKS,
MASIAH!
