Here is a picture of a leaking rear tensioner. The oil is flowing down on top of the passenger turbo but also collects on top of the tensioner after a while to form the goo in the picture.
For the rear seals the front does NOT have to come off, they can be done with minimal removal of parts and a tool to hold the chain spring plate in place. The front seals also do NOT require the lock carrier to be removed, it just has to be slid out which is how you do the t-belt as well if you want to cut the time in half.
If you get told the entire lock carrier has to come off to do this find another shop. The guy I use does the belts and front seals in 3.0 hours labor and he completes the job in 2.5 to make book. That being said it's probably going to take a long time the first time you do it, especially if you pull the carrier. And it's handy to have the cam lock bar when doing this.
I'll be doing the belt water pump and etc. and a complete reseal on this particular car Saturday morning if you would like more pictures.
