The TDDI needed a good service including the cambelt. I know a lot of people do this by simply slipping the belt off and replacing it but I did it belt and braces using;
Flywheel locking tool
Block timing pin
Cam locking bar
etc etc.
Also did quite a bit of stripping down in an effort to get rid 10+ years worth of gritty oily grime off the car. Note you can use a bit of studding on the lower block to support the engine when the mount is off rather than on the sump. I did this as the sump was already dented and I did want to damage it further.
The cambelt change was done in late 2009, in fact over the xmas holiday when I had a few days off.
Stud on jack to support engine
Timing pin in, alternator off, alternator bracket off for access and cleaning
Flywheel locked, you can see how much oily gritty crap is on the engine here.
Alternator, alternator carrier, engine mount on the floor
Other stuff on the floor (ignor the gearbox and strut LOL)
Aux belt Tensioner and how it is fitted
Cam locking bar
Old tensioner was out a bit as was the timing.
All done and most of the bits that were swapped out. Includes water pump and stat.
A really easy belt to do although I went way over the top.
