Unhappy no compression on cylinder #4

I have a 2010 F350 with a 6.4, it has no compression in #4 cyl. Well it has very low about 45 psi vs 300 on the rest of cylinders, debating wether to take it apart and check buned valves or pistons. Any ideas before I do that?
Any help will be appreciated, Thks

Is it stock, or is it deleted? What happened? How many miles? My guess is you melted a piston.

Hard to tell what caused the problem with such little info you provided... Even then it will still be a guess but at least with more info it would be an educated guess! Sorry to hear, good luck with your repair. Hopefully your under warranty still.

Were you running on of those crazy tunes like +210HP?

I hope so because then it's just your fault. If not then what caused this is unknown.

I'm actually happy when sometimes because breaks because of my doing. When it's not then I get concerned.

Hope the cost of the repair is not too much.
Dang that's just a bummer.
