RPM, If that’s a 99 chances are those plugs do have O-rings that just need to be replaced. Very few cylinders are floating around without o-ring plugs.

Those need to be pressed out, then either buy a new set for 60 bucks or just the O-rings (Swedetech has them listed), if it were me I’d just buy a new plug set.
