Technician A is correct because piston rings are designed to form a gas-tight seal between the piston and the cylinder wall to prevent combustion gases from escaping. Technician B is also correct because oil control rings can typically be installed by hand without the need for special tools, although care must be taken to avoid damaging the rings.
