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

Not very knowledgeable in this as most of yall, but if the manifold was leaking wouldn't there be more than just that part of the valve cover melted? Like the piping around it? Just thought Id ask from the peanut gallery lol
And there should be a loud noise that you might be asking questions about. Or be concerned about.
