Should I pull that black box to inspect or replace it? Everyone is telling me that the PCV is probably going bad. Car has just under 50k miles.

I can also hear some ticking noises from that general area.

is the smoke blue or black?

black smoke is unburnt fuel. This is normal.

blue smoke is oil, and might be considered normal, it could come from a few different places. Do you have a catch can on it?
