Does anyone know a rough time for removing the passenger exhaust manifold gasket, suspect either a gasket a cracked manifold as it came so suddenly but it also seems to have quietened down significantly in such a short period also which is strange as the engine was cold when started to look again, I also took it for a drive to warm it up and it is still much quieter, a, going to investigate further tomorrow in the light but would just like to know a rough time if I removed the drivers engine mount and undid the passenger mount to swing engine over.
Thanks

im doing the same job right now.
theres a few bits to take off, its got near to no access (im working on the floor, no ramp). ive wrecked my manifold heatsheilds because the bolts were rusty, so order those first.
my problem was a broken stud at the rear.
take out battery, power steering resovoir, bonnet alarm doodah. undo bastard bolt and take out dipstick tube. remove downpipe, drop oil and remove oil filter (makes it easier).
undo bolts, try to get the heatsheilds off but they are normally rusty. smash them off.
7 bolts on the manifold, three top ones from the top, front bottom one from the top with a "bent" spanner, rear three bottom ones from underneath. i used a 3/4 breaker bar and 6 point socket and got them all out easily.
good luck, its a "big" job, its gonna take you a good 10 hours working alone.
the stuff you need -
studs, nuts, manifold gasket, downpipe gasket, nuts/bolts to refit the middle 2nd to the 3rd section of exaust, new nuts for the downpipe.
iŽll get the part numbers in a sec, it all cost me 60 quid.

but ive just seen that you are a jag mechanic, so iŽll revise that to 6-7 hours. if you know your tools, you know what you are doing on a v6.
i dont, i just fix our cars to stay on the road.

Thanks for your reply, already knew what was involved so basically just after a time, after going out for a drive again I've come to suspect downpipe gaskets and the sound resonating around the manifold area and under the car as originally the sound was only passenger side and now I'm getting a blowing noise under car on the driverside towards the downpipe end, this manifold gasket was only recently replaced and I know its still not blowing, I fitted new downpipe gaskets when I changed my clutch not that long ago and now the blowing is heared on both sides it sort of makes sense, I will get downpipe off again tomorrow and check for signs of blowing, hopefully its just crappy downpipe gaskets.

they are only 5,46 from Vx i believe?

Can't remember price but not expensive and a few minutes work to change, so I'll start by checking those and if at fault will buy some more.

Problem fixed, decided to order 2 downpipe gaskets while in work today, to my suprise the downpipe gasket on the passenger side had already failed, I only changed them in August.
