I Have a 2013 f150 3.5 ecoboost. Valve cover keeps burning on passenger side. What is causing this? Cover looks fine from inside so it can’t be the valves.. I’m just confused. I replaced the burnt valve cover with a brand new one and same burn. Same spot. Weird. The water coolant line that runs beside it gets really hot but I don’t think it’s causing this burn.. are coolant lines supposed to get hot to touch? Thank you
What's going on with that COP that it needs duct tape?? This looks like the wiring there could be arcing to the stud holding the cover on. Looks like several smalls burns to me. Is the wire insulated properly?
