Watch "Boxster Engine noise what is it?" on YouTube


Recommended Posts

The standard diagnosis technique is to remove the serpentine belt and run the engine for a few seconds to confirm this eliminates the noise.

Check all the ancillaries for bearing wear.

Then put the belt back on and use a stethoscope - like "Engine Ear" to isolate the offending part.

How did you diagnose P/S pump?

With a stethoscope you can easily detect the culprit.  It sounds like a bearing is going bad possibly in the alternator, causing the windings to drag and grind on the sides.  You'll normally see little flecks of metal nearby.  it couls also be the power steering pump, its really hard to tell with that recording, as you are moving around.

 

If you don't have a stethoscope, you can use a very long screwdriver.  Place the metal end near the suspected culprit, CAREFULLY, and put your ear to the plastic end.  Trust me, you'll hear a bad bearing right away.

 

Good Luck
