The noise is alarming, almost more than the thought of trying to strip down and find the offending item

If it is a metallic sound not a miss-fire, then you can always strip off the cambelt cover, double check everything.

I think that's what I'll need to do. Definitely metallic. Didn't run it long enough to decide if any misfire or to let coolant circulate or decide on any other problems following the work.
Can't get it straight in my head, but hoping there's something stuck in around the belt. Failing that it must have got inside somehow

Silly question time & not intended to cause offence,  but did you stuff the inlets with paper towels / tea towels? Could anything have fallen down into one of the pots?

Sure you did, just double checking the basics 

[jonny2112]

No offence at all pal 
Yes I did block the inlets. Convincing myself that there is a missing washer and that it has found it's way into the cambelt housing at best (but why so noisy?) or in beyond the water pump at worst.
From my point of view it really needs to be the washer so that there is at least something to find.

More likely down the coolant tube where the stat sits, can't see how it would work itself into the cambelt area that's sealed to prevent road dirt getting in there. Unless you removed that cover for any reason?

I have no experience of V6 cambelt change, not sure if the water pump can be removed on its own? I know its aux belt driven, but have a feeling the cam belt has to come off  Could be wrong though

Don`t hypothesise or procrastinate John, get your spanners out

Yes Rob, will do. Just don't know where to start? If it stays dry and I get home at a reasonable time, namely in daylight, I'll have a look.
I haven't had the cambelt cover off, but guess it may be open at the back, against the engine. Would also have thought that anything dropping in there would have been ejected by the belt.

The bag pipes off, plenum (if extended version), auxiliary belt after undoing the bolts on the water pump pulley and torx bolts on the power steering pump, remove auxiliary tensioner, remove cable tray and then cam belt cover.
Can be done with cambelt cover in place but if the pump is stuck then you`ll probably damage the cover when trying to release the pump. If done with cover in place, dont drop any bolts

If I end up going down this route, can the water pump be reused? Or should it be replaced once removed?

Yep as long as there`s no bearing noise

hi Jonny. If your unsure about getting the water pump out I'd be inclined to buy the oof cam belt dvd which shows you exactly what to do to get to that point. . . Simply follow all instructions but skip the cam belt bit :-) i was also thinkin about this. If the washer has been cracking the water pump i wonder if its possible the water pump teeth are damaged? Just thinkin cos it spins round so fast?

[jonny2112]

I think I have one of those discs actually, good thinking 

[jonny2112]

Started to strip down tonight but bad light stopped play 
Aux belt is off, cover fastenings all removed, but need to take some of the pulleys off?
Should have an hour or so tomorrow before work to have another bash
