I can agree With you on that one..


I have mounted some new Collins engine Mounts on the car, because of the old original ones was worn out. The sound was not there before fitting them and the New cam belt and tensioner. The noise can be related to a diesel engine where the engine plastic cover is vibrating and making some resonace sound through the enginebay.


Was out in the garage listening to the noise again, and I can feel and hear the droning noise when I attach a large screwdriver on the front of the turbo/wastegate bracket..
