[QUOTE="GraniteRiver, post: 1853995, member: 55719"] Quick background, 2019 Raptor with 42k miles. Only mods are suspension and SVC Intercooler. Never tuned, no engine mods. Climbing a hill on the freeway, heard a noise and the truck started vibrating/shaking badly, flashing check engine light. Limp the short drive home. Pulled all the plugs and cylinder 5 plug was covered in oil and missing the ground electrode. I changed all the plugs, still misfire. Changed the coil, then swapped coils and no change. Have it brought to the dealer and with the scope they see piston damage. Any ideas on the cause of this one? They are going to pull the head and investigate further. [/QUOTE]
