Spent a few hours this afternoon sorting out an MOT fail on mine (I know, hangs sorry head in shame etc), got an exhaust blow from the manifold joints to the rest of the exhausts. Damn that's a bu55er. Not a lot of room down there, as some of you will know. Got there in the end with the aid of my trusty plumbers blow-torch to heat up the area around the stud and a fair bit of hammering. Not quite the full "that was heroic and I deserve a Nobel prize", but close. Used to be so much easier when I was a proper mechanic and worked in a big shed surrounded by loads of useful tools and vehicle hoists etc.
