Check the ignition system for gremlins. How old are the plugs? Gapped correctly?

The fouling looks kinda thick.
Mabey too rich, rather than lean?

that's a groce plug mate

I sure hope it's old as fuck. Either you're running way dirty or the ignition system can't get a spark through it.

this plug is about a month old. i've just about replaced everything ignition wise

Is it sucking in oil? Time for a compression test?

Also all the other plugs looks fine

ive compression checked every cylinder and they're all about 150 to 160 psi

compression test.
Also, check valve stem seal.

Is it fuel injected? I suppose an injector stuck open could gum the plug up like that while the O2 system tries to lean out the rest of the cylinders.
