holy crap those compression numbers are something i would be concerned with!
240 being the low and 100 psi between high and low is huge.
Heck i would consider 320 psi across all of them low , but dropping down to 240 is extremely low. something is seriously out of wack. I would almost wonder about blown head gasket because that is super low.
could try pressure testing the cooling system with all glow plugs out and then hand barring the engine over to see if coolant comes out any glow plug holes if you can pump up the cooling system but it drops psi and no external leaks
