does any1 no how 2 change the VALVE stem seals on a volvo T5. without taking the head off. PLZ

Nearly Impossible. You would have to fabricate tools to do it.

Better off taking the head off.

Why do you need to change them?

Are you 100% sure it is the Valve seals leaking and not the turbo going bad?
It could also be a bad vaccum line for the Vent box setup broke. That will cause the car to suck oil into the system and burn it.
