For years I have been using a rubber hose pressed to my ear to listen to engine noises, thinking I could listen for potential problems or unusual sounds to help me diagnose engine malfunctions. That is, till I broke down and purchased a NAPA Mechanic's Stethoscope . Whoa! Was I listening in the wind. This little jewel picks up sounds that I never heard before! I can hear valves opening and closing, rockers rocking, water pumps pumping, and all kinds of other music to my ears. The loudest part of my engine is my darn Delco-style alternator. What a racket! Gotta be some bearings trying to go out. Grinding noise that don't sound good. Back to Autozone. (Is there a better quality alternator out there?)
My wife thinks I am nuts, scrunched over the engine with this thing stuck in my ears, playing doctor....
