To change the valve guides and seals on a 1995 Mazda MX-3, first, remove the valve cover, timing belt, and cylinder head. Then, extract the old valve guides using a guide puller, and install new ones by pressing them in carefully. Replace the valve seals by removing the old ones from the valve stems and installing new seals using a seal installer tool. Finally, reassemble the components in reverse order, ensuring proper torque specifications are followed.
To replace the valve stem seals with the head on you must bring each cylinder up to top dead center, pressurize the cylinder with an air chuck screwed into the spark plug hole. (this prevents the valves from dropping into the cylinder) Now the seals on that cylinder can be replaced. The process is repeated on each cylinder. Note: you must prevent the engine from rotating when the cylinder is pressurized.
You'll have to pull the heads and have the guides and seals replaced. Bad seals are usually an indication that the guides have worn as well.
