I finally put my turbo back on this morning after waiting a week or so for some new tools. Anyway, everything looks very nice now that it has been cleaned up and I have used all new studs, nuts and washers.
When the turbo was reconditioned they removed the pipe that the oil feed pipe slides on to. When I refitted it I tightened it up as much as I could by hand assuming that when I refit the oil feed pipe and then the nut at the top it would tighten it up enough to stop any leaks. This has not been the case. Oil is leaking from the pipe so I have a few questions...
Is the way I have connected it back up correct?
I believe the torque settings for the nut to be quite low and therefore know that it could go tighter but didn't risk it, is this right?
Do the holes in the hollow stud need to be facing a particular way? I assumed they didn't as the end of the oil feed pipe is a circle.
I have used new washers underneath and on top off the oil feed pipe.
The surfaces are probably not flat.
Take it out, clean everything well, get some new copper washers and re-install it carefully and vertically.
I found that it needs to be a bit more tight than the Vaux torque value.
