Q: Oil leaks when engine is idling

asked by on

I saw an oil leak on the passenger side of my car, just behind the tire. What could be causing it?

The oil leak may be the oil filter or oil pressure sensor. This is if the leak is engine oil. If it is power steering oil then the rack and pinion is leaking. If the brake fluid is low then it is a brake line or caliper leaking. Have a mechanic diagnose the source of the leak for you if you cannot identify where it is coming from.
