By using an air compressor to hold the valves shut, while you work on them. Each spark plug is removed and an adapter is used to screw into the plug location. This adapter is then connected to compressed air. Talk to may reputable mechanic and he can help you.The above answer is right WHEN replacing the VALVE SEALS. But the question was about replacing the valve guides. YOU MUST remove the heads and take them to a machine shop to have the valve guides replaced. NO OTHER WAY.
Yes, you remove the rockers, add air pressure in the cylinder through the plug hole and use a valve spring compressor to remove valve spring. You can now change the valve seal.
A valve spring "keeper" or AKA a valve spring "retainer" is used to lock a valve spring to the valve.
Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another.Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn ringsFaulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common.

Remove the valve cover by removing 10 mm bolts (#4) and hoses. Pry up slowly valve cover. The gasket set comes with 4 spark plug gaskets and one valve cover gasket.
Valve pocketing is when a valve is hammering the valve seat.mostly due to miss adjusted valve spring/wrong valve spring/to strong of a valve spring or valve stem to short.Makes the valve seat deeper.
to do this ,( if i understand your question), the oil valve seals are located on each valve inside the valve springs. To get to them you must remove the head and use a spring compression tool to release the valve springs to get to them.They have to be replaced ,there is no " repair ".Yo can also pressurize each spark plug hole with compressed air to keep the valves up so you can replace the seals, this will save you from removing the head as long as the valve does not drop into the piston chamber.Hope this helps.
There are tools to do just that. Doing one cylinder at a time, you remove a spark plug and install a quick disconnect air fitting in its place. Connect your shop air compressor line to it and maintain air pressure, 100 psi is good. The air pressure will hold the valve in place during this procedure. Now you will need the proper tool to compress the valve spring and remove the retainers (keys) then the valve spring. Remove the old valve seal and replace with a new one, then reverse procedure to install spring and keys. Your local auto parts store should have the tools you need for sale or rent.
only if a three valve head after 2005
