Default Timing Chain Tensioner Seal Replacement - Lock Cam or not??

Morning All,

I have a 2002 Boxster S and have a significant oil leak from one of the Timing chain tensioners, I'm planning on changing the 'O' ring and seal to cure this.......

My question is a fairly simple one:

Do I need to lock the cams to do this?

I appreciate there will be a lot of people suggesting 'they would', but I cannot see how removing one tensioner will have any effect on the timing. Surely the guide rail will prevent too much movement of the chain? I am not doing any other maintenance to the car at the same time and I do not plan on having the tensioner out for any longer than it takes to swap the seals over.

I guess what I'm really after is somebody (preferablly lots of people) replying to me with previous experience of simply removing the tensioner, changing the seal and O ring and not having any repercussions.

TIA
