Put the new gearbox put in the weekend, wasnt too hard of a job. No more knocking noises. My mate recons its a bearing on the old box thats gone.
So all in all happy with the job. Now i just need to get my boost leak sorted. Ive sourced the leak. its the plastic pipe that comes from the right turbo and goes under the manifold.
Then just a couple of bushings to have it mint!
Heres a few pics..
Thought id post this one for the crack That was some weekend....
