Still Another Chainless Wonder!
I too just returned from a St. Louis vacation/balance shaft module replacement done by Oilhammer. My car also sounds great! All my "normal" rhythmic chain noise is gone and in addition another troubling sound my car had it gone! It had, within the last year or so, developed a whirring noise that was heard most clearly when slowing down and when the car downshifted. It had the sound of something rubbing where it shouldn't have been. Well, it's not doing it anymore! I know it's been said over and over, but after chain removal it sounds like new, or maybe better than new.
Brian did a great job! In the 5 or so hours that it took him to give my car the complete treatment (gear drive balance shaft module, water pump, alternator pulley, engine mounts, trans flush, bleed the brake lines) he never stopped working! He is clearly the best there is, and deserves all the praise he's received here. Thanks again Brian!
Personally, I don't care if I fixed what wasn't broken. All I know is, this car WAS going to break eventually. The noises I had been hearing were NOT normal and were NOT good! I felt like we were driving a time bomb. Well, it's now been defused, and I feel great driving it again!
