I’m trying to re-attach the exhaust manifold on my 1991 200 tdi. How should I get the not onto the stud that is underneath the manifold, in the centre? I have tried using blutack to keep the nut in a long 17mm socket and feeling my way in, but can’t get it onto the thread.
Change the nut to an M10 flanged nut, these then have a 15mm head which means a smaller socket can be used, and because it has a flange you can push it onto the stud, same for gbox to flywheel housing nuts.
