Hi Luis Mondolo,
There are 2 ways of doing it and it is not going to be easy.
!St and normal way is to remove the cylinder head to replace the seals.
2nd way is to remove the camshafts and with regulated compressed air into the cylinders from the plug holes and special tools to remove the valve springs and replace the seals.
It would involve removing the timing belt.
