ah, yes!
The timing is correct!, tension, teeth in correct place with the belt!. Mpg is as normal too!. Just put a new fuel filter on so willl see if that helps, though not sure if its the correct filter as the one that has just came off has 6.4 Bar stamped on it and the new one is 6.6!!??? (yet another post coming)
If it doesnt, I will get them to do a compresion test nex tweek.
