Finally got my M52TU manifold replaced with an M54B30 one. I have got some photos and will do a bit of a writeup to see if it can help anybody when I have a chance.
Started this last Saturday PM, expecting it to take a weekend. Well it didn't... Spent the week haggling to get to work, finally got it finished today so it's taken me about two weekends in total - but I'm no mechanic and I only did a couple of hours last Sunday.
Now I just need to be able to get out and really test it, at the moment it's so wet that when I've taken her out I just keep spinning the wheels.
