it is essentially the same thing as a piston ring in a piston engine. there is one at each tip of each rotor, and they sit ontop of a spring that keeps them pushed against the rotor housing to seal each combustion chamber off.
if you have a bad apex seal you can replace the apex seals and side seals depending upon the condition of the engine, if the housing or side wall is worn or scraped badly than you will need new housings and possibly side walls. but your motor may run depending on how badly worn the apex seal is.
Bad Apex seal
Yes. You must take the engine apart.
