After the 6.7L Scorpion Motor was introduced in late 2010, it was hailed throughout the 2011 model year as an all-new and revolutionary diesel. While it was—and still is—an impressive engine, even with all the power of Ford behind the development, a few bugs needed to be worked out.
One of these bugs was an unfortunate leaking of oil from the new engine’s space-age composite oil pan. These oil pans had a new ¼-turn drain plug for the main sump, and experience showed that after a few oil changes, the pans began to leak. The result was nasty oil spots, whenever and wherever you parked your truck. Not cool—and quite messy—to say the least.
