A worn out valve guide seal, a faulty fuel level sensor and oil leakage can cause the Mazda CX-5 to consume a lot of oil. A foul smell may signal oil or fuel leakage, harmful exhaust gases invading the interior of the car, or a defective drive and accessory belt beneath the engine. A knocking or tapping sound is heard when gasoline ignites prematurely in the combustion chamber of the cylinders, which can cause major damage to the piston.
A defective gauge, a clogged inlet pump screen, a worn out pump, or a faulty oil filter can cause low oil pressure. A defective piston ring, a worn out head gasket, or a faulty valve may cause low compression in the engine. When the piston oil ring is defective or when the oil passage is clogged, engine oil may leak into the air filter box.
A loose gas cap or a worn out piston can cause the dashboard light to illuminate excessive. A faulty spark plug or a defect in the car control computer can cause the CX-5 to pop and lock.Learn more about Car Makes & Models
