It could be the coolant line that is causing the issue and yes they do get hot but there usually engine temp hot which could range from 190-215 degrees could be higher depending on load conditions to. If the valve cover isnt leaking i would put it back on and run the truck and get a temp gun to see what the temps are in that general area.
Valve cover keeps burning..
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
