Message: <blockquote data-quote="stephen" data-source="post: 117877" data-attributes="member: 120">well, mine have not reached 75k miles and already the following two items have been changed:- Accessory Belt and Tensioner Failure  Worn tensioners and idler pullies will sound like a squealing noise from the engine bay. Belts should be inspected for cracks regularly.  If a belt happens to snap, the cooling system will fail as the water pump will cease to operate. Power steering and the alternator will also fail to work. Again, pull over and shut the car off immediately should you suspect a belt failure or see the temperature gauge rise past the 3/4 mark. Oil Seperator  Non M cars. If you have a poor idle and periodic Check Engine lights, you may have a bad oil seperator.  This valve tends to go bad and introduce a vacuum leak which produces the above symptoms and will eventually strand you somewhere.  We started seeing these a year ago and we are now repairing more and more cars with this problem.  Typical mileage seems to be around 80k.  The good news is that the part is only around $75..the bad news is that the labor runs about 4 hours, depending on the year of the car.  This one below was changed as a "precaution" and also to increase performance using Powerflex brand :- Lower Control Arm Bushing Failure  Common symptoms for torn or cracked lower control arm bushings are undesired front toe changes during cornering, vague and rubbery feel in the steering, and vibration experienced while braking at freeway speeds. Non-M bushings are commonly replaced with M3 bushings to increase performance with little to no change in comfort.</blockquote>
