CCV fitting borken

ok guys... ended up cracking and finally breaking the ccv fitting during a valve cover gasket fix... got it rigged with some hose but it's not great, leaking...

here's the question, would/could this cause anything horrible to go wrong before i can get a replacement? it's definitely running a bit rough, in fact an obd2 reading shows cylinder #4 misfiring... strange, as i did put in new plugs as well...

what a pos that valve is or what an idiot i am for not being able to pull it out without breaking the thing...

thanks for the advice and the vent...

Which fitting did you break? The one with the orifice??

Your problems sound like they are from the vacuum leak, that you said you have from trying to rig up the fitting.

Usually the PCM recognizes misfires from unexpected changes in crank angle from the CPS. A bad enough vacuum leak, could cause misfires, or at least rough enough running to fool the PCM into thinking it sees a misfire.

the one i broke is the one to the rear of the valve cover...

pcv in rear, ccv in front

what year? they were made diffrent through the years

man... am i not following procedures...

Since the rear is directly connected to the intake manifold, I would think you have a vacuum leak.
