I have a fairly steep driveway (75 yards long), sometimes I think I hear a buzzer about half way up the driveway (just after the steepest part - 30 degree slope). Maybe just buzzing ears from the headers? Could it be an
oil pressure, pick up warning? A little worried as I just purchased a home in the country with just as steep driveway, but it's 200 yards long. Dangerous to engine life, or not, if I keep it under 2000 rpm for the time it takes to climb the driveway? Buzzer only goes off going uphill (I think, Cobra hearing, never used earplugs).
Any thoughts?
