Not wanting to start a new topic for similar issue so I will post my experiance here. I tried fitting an exhaust and all turbo studs sheared, so thought best remove turbo, and manfold studs sheared, also wastegate exhaust pipe had to be removed and those sheared as well (good start). A colleague of mine drilled out the turbo studs and that has now been cleaned up and new studs fitted ready to back on.
Could possibly do the manifold studs in situ but as wastegate studs need coming out thought about removing the whole wastegate section of the manifold. Now scared these will shear and reading others experiances even more scared. Last thing I want to do is crack main manifold or remove it.
any one got the wastegate studs out in situ? whats likelyhood of wastegate manifold studs shearing?
Any advice? sounds like these are common issues.. Thanks
