One of the symptoms of low oil pressure is:

• A. A ticking sound
• B. A squealing belt
• C. A dim headlight
• D. A misfire

Answer: (A)

Low oil pressure means the lubrication system isn’t delivering enough oil to engine parts. That film of oil between moving surfaces is what quiets metal-to-metal contact and prevents wear. When pressure is too low, parts like the hydraulic lifters and valve train can’t stay properly lubricated, so they begin to clatter or tick as they move against cam lobes and other components. That ticking is a common warning sign that lubrication isn’t adequate and should prompt an immediate check of oil level and pressure, and stopping if an oil pressure warning is present to avoid engine damage. The other options don’t fit because a squealing belt points to belt drive issues, dim headlights point to electrical charging problems, and a misfire comes from ignition or fuel problems rather than lubrication.
