Not yet. Started but struggled to get the rear breather pipes off the back. Thought I might be able to get the cover off first and that might be easier to get the pipes off at the back. Was late though and struggled to get the valve cover off as it was stuck pretty tight and didnt want to damage the gasket or mating service as I dont want to have to fork out for a new gasket at the moment.
Il try again soon.
Do you think my theory about the tensioner could be.right @rich83 ?
I also want to see if I can.borrow a compression gauge off a mate to check each cylinder before taking the cover off. Am I right in thinking that I just unscrew the spark.plugs and screw in the gauge and.then turn the engine over at the ignition whilst checking the gauge?

The larger pipe is a pita. Im sure someone on here can give you some pointers. Its best i don't say how i got mine off. :slap:

Pesky you've got to give yourself the best chance when doing anywork in this area as its all tight - plenty time - good lighting and good tools to start with.
Before removing the cover set the Tbelt to all the TDC marks for the necessary pulleys as per the links previously given - that way you can check if the chain has jumped a tooth or the belts jumped any teeth before a compression test as that's going to involve the starter motor which will do more damage if your not careful.
The valve cover removal may again take a bit brute force or a knock with a plastic hammer.
The hoses just work on them with a pick and a bit pen oil spray they will come off.

Thanks for the advice guys
I will try to get the timing clarified before the compression test then.
Turn crankshaft to TDC, marked with tip ex etc. Then go up top, remove cam belt cover and check that the cambelt pulley is also lined up correctly? IF these two are correct, then il remove the valve cover, HPFP and cam cover and look at the cam chain/ observe camshafts turning as I turn the crankshaft. IF both camshafts are turning then il try to insert the tool @dazza kindly lent me. :notworthy:
Ideally I want to see a damaged tensioner which would back my theory up that the tensioner failed and leaked oil resulting in low oil pressure, which caused the timing to go out, resulting in it cutting out and refusing to start again
