How do you remove an expansion valve from a car?
The one thing I would add is that you can remove the evaporator core/expansion valve assembly entirely from inside the car (internally there are 10 mm bolts connected to the aluminum coupler that sits in the firewall. Remove these bolts to pull the “cooling lines” away from the firewall and remove the evaporator assembly).
How much does it cost to replace a Toyota expansion valve?
The Toyota factory manual just recommends to blow out any debris with compressed air in there. If it is mechanically stuck, then it probably is better to go ahead and put in a new one instead of doing the same job twice. So, I think anybody can do this job for under $100 with the right tools.

When do you switch to an adjustable valvetrain?
If we switch to solid lifters it is mandatory that we convert to an adjustable valvetrain (I would also say that converting to adjustable valvetrain is mandatory in ALL racing applications as well as any application where we want to have accurate control of our valve lash setting). Not doing so is asking for serious problems!
