Mercedes Benz repair: THANX FOR ALL YOUR HELP!, catalytic converter, mercedes

Question
IM SO SORRY I FORGOT TO INCLUDE WHAT KIND OF CAR IWAS INQUIRING ABOUT. ITS A 1987 MERCEDES 300E 6 CYL FUEL INECTION.I WILL START PRICING THOSE PARTS TOMORROW. ALSO,WHEN YOUR PLUGS GET WET WITH OIL, WOULD YOUR CAR BURN OFF OIL AND SEND THE SMOKE OUT THE TAILPIPE? THANX AGAIN! DAN WILLIAMS

Answer
Remove the oil fill cap, have someone else crank the engine, if smoke or large blast of air comes out you could have serious damage, a good used engine may be cheaper than repair.

The oil will burn off if it is not catastrophic engine damage causing it.

The catalytic converter will not be happy and may melt down if it is in poor condition.
