(2000 civic with d series engine) Cyl 1: 0psi 2: 140 3: 50 4: 130

Not entirely sure if I did everything properly I didn’t wanna go too tight with the tester so I might do it again.

So obviously I need to open this up and change all the gaskets I possibly can but I’m wondering what the 0 pressure might mean? Gasket just entirely blown up or something unfixable happened to the engine? Or else?

Thank you
