Seeing as I work for myself MOT, service and repair I finally got round to doing it (own cars always take a back seat - lol)
Once stripped I found that the cambelt timing on the "factory fitted" original belt was out on the Inlet cam by about 1/2 a tooth but this could have been due to wear/stretch in the belt.
Used a Dayco kit KTB408 which has 1 x tensioner 1 x idler and the belt
Easy to time up engine and not a difficult engine to actually get to the belt etc
After replacing the kit the engine is now quieter and a small rattle has also now gone (poss worn tensioner) and all is well with the drive and power etc
So all of you who may be cautious of doing the timing on the variable inlet cam pulley I can say it is no more difficult than a "normal Zetec type" engine and in fact it is slightly easier as the crank pulley is on a woodruff key and not free spinning.
Its all a load of rubbish mate people see VVC and s**t them selfs, can get them done in a hour at work with the air tools as said its just a old zetec engine nothing more! you will prob find the intake cam was out due to a slight bit of free play in the pully because of the loss of oil pressure as the engine stopped
