Guest Guest_Rob_* Posted October 9, 2008 Report Share Posted October 9, 2008 When accelerating my volvo sound like a hissing noise. driving on the freeway the sound turns into a chater when letting off the pedal... It almost sounds like an exhaust leak--lifter.. But what I don't understand is that the vehical also has started a wounderful little knock sometimes while in my drive way with the hood up... Also the injectors sound loader than before.... I have had work done at the dealership... Exhaust the 2 down pipe with cats--- crank box--- new coil and plugs--- visco coupler--- turbo oil leak fixed-- new o-ring kit for oil pump.... And the noises are still there... the injectors just started...... Need help............................ Link to comment Share on other sites More sharing options...
S8ET6 Posted October 9, 2008 Report Share Posted October 9, 2008 Is the lid to your air box on completely? Link to comment Share on other sites More sharing options...
Guest Guest_rob_* Posted October 11, 2008 Report Share Posted October 11, 2008 The air box is on completely... Dealer told me that the ticking was the injector... Told dealer that the ticking was never that loud until I got it back...... Link to comment Share on other sites More sharing options...
