Please can anyone advise as to where all the fixing bolts are between the turbo and engine block? I have removed the 3 17mm. nuts on studs that I can find, and have removed all from the exhaust manifold but I still cannot get the turbo off. I need to remove the turbo to replace the cracked exhaust manifold which is now loose and ready to remove once the turbo is off. Any help will be very welcome. Thank you.
