If it's new school almost certainly 3-piece (the crank arms are separate and bolt onto a spindle)

Moving this thread to tech/resto as you may get a better response in there ;)

Crunching could be a sign that your bearings are on the way out or there's some shite in there - if they're not a sealed unit stuff can get in
New BB wouldn't cost much for a new school setup - recommend getting a sealed one if regreasing your current one is no good

Ah cool thanks. Yeah I think it’s maybe like 5/6 years old,seen better days but I picked it up fairly cheap so can’t complain about giving it some TLC.
I see there is a bolt that goes through the crank into the bottom bracket, I assume this would mean it’s a 3 piece set up?
