Success! The manifold is off, leaving the turbo and even the shield insitu!
Here's the proof -
Manifold not cracked, gasket is shot to bits near where the missing stud was.
Now, thats the hard bit done. I now know what tools i need for the job, and i will do a short how to guide on this, as its a common CT engine issue.
I had hell trying to find a 12 point deep 10mm socket for the turbo nuts underneath, i had to buy a set from Halfords, with the assitance of a 3/8 to 1/2 inch adaptor, a bendy join, a few extension bars and a trolley jack handle for leverage, these came undone fine. The oil drain and water drain is still connected, the turbo does not have to move too much.
The hardest nut to access is right underneath next to the turbo, a deep 10mm is too long, a short 10mm means you cannot get a ratchet on, and a 10mm spanner is too thick to go over the nut and not foul the casting on the manifold.
Luckily because they were so loose, i managed to shift the turbo back, used a flexy join with the short 10mm and bit by bit, it came undone.
On reassembly a modified 10mm spanner will be used for the job.
The heat shield defeated me. It curls round the turbine housing and a cast mounting sticks out preventing it from being removed. Depending on time, i may remove it and mod it, but it could be left in place.
The fire ring on the turbo/manifold join will be replaced, a dab of superglue will be used to hold it in place when refitted which im sure will burn away once up to temp.
I need to replace the missing stud, assuming its not snapped off! I need to check this first as it may mean the head will have to come off! Sure its ok though.
