2. Oil Leaks
Oil leaks can cause low oil levels, leading to severe engine wear. Common culprits include:
- Worn Gaskets: The valve cover and oil pan gaskets can wear out over time.
- Damaged Seals: Crankshaft and camshaft seals can become brittle and start leaking.
- Poor Maintenance: Neglecting oil changes can lead to sludge buildup, which can cause leaks.
3. Excessive Oil Consumption
If you’re constantly adding oil, it’s a sign of trouble. Potential causes include:
- Worn Piston Rings: This can allow oil to seep into the combustion chamber.
- Valve Seal Failure: Worn valve seals can lead to oil leaking into the cylinders.
- PCV Valve Issues: A malfunctioning Positive Crankcase Ventilation valve can cause excessive pressure.
4. Engine Misfires
Misfires can be frustrating and may indicate underlying issues. Common causes include:
- Faulty Spark Plugs: Worn or fouled spark plugs can lead to misfires.
- Ignition Coil Problems: A failing ignition coil can prevent proper spark delivery.
- Fuel Injector Issues: Clogged or malfunctioning fuel injectors can disrupt fuel flow.
5. Check Engine Light
The check engine light can indicate a range of problems. Causes can include:
- Loose Gas Cap: This can trigger the light without any serious issues.
- Oxygen Sensor Failure: A faulty sensor can affect fuel efficiency and emissions.
