Replace 1GR-FE valve stem seals

Have you done it? Do you have wisdom and tips to share? There isn't much at all online for this engine.

I'm looking for how-to insights, not diagnoses.

A thousand thanks!

 

Is the engine out or are you planning on doing this in frame or in the vehicle?

 

Thank you for responding. The engine will remain in the vehicle.

 

Did you find any wisdom or tips for this, as I need to do this to my 2015 and am also looking?

Thanks
Keith

 

I’ve only done Honda motorcycles.
I hacked up an old spark plug and welded a 1/4”NPT nipple on it with an air hose fitting to pressurize the cylinder keeping the valves closed while removing the keepers and valve springs.
I know some guys run clothesline or para cord into the spark plug hole and run the piston up to keep the valves closed.
I don’t know if either technique will work with the Toyota engines.
