On the Non-turbo Engine I guess it is possible to remove the Timing Chain Tensioner Spring and the Piston would slide out. That would remove the tension on the Timing Chain Rail.
If it is a 617 Turboed Engine you need to remove the Timing Chain Tensioner because there is what is called a Ratchet Device made into the Timig Chain Tensioner.
The short desciption is that the Ratchet device only allows the Piston to go one direction. That means you can remove the Timing Chain Tensioner Spring and the Piston is not going to come back out unless a lot of force is used on it; if it is possible to move it back at all.
Better to read up on the details of how to do it and make your own decision.
