Why is My Car Leaking Oil?

If you have noticed oil stains underneath your car, your oil levels are low or you can smell burning oil, then your vehicle could have a leak.

Understanding what has caused the leak is the first step to finding a solution, as several issues could be to blame.

Overfilled Oil

Something as simple as overfilling the oil can cause a leak.

You can usually tell if this is the case if there is a puddle of oil under the car, but the dashboard engine oil light is not flashing.

A Rusty Oil Filter

If your car’s oil filter has rusted or doesn’t fit properly, then this can cause an engine oil leak.

Oil filters will be changed as part of a car service, so booking one regularly can help you avoid this issue.

Engine Overheating

If the engine overheats, this can cause the head gasket to blow.

A blown head gasket can cause damage to the previously sealed coolant and oil passages, meaning these liquids could leak into the cylinders.

Damaged gaskets are likely to cause oil leaks now or later down the line.

Loose Oil Filler Cap

Simply tightening or replacing a loose or missing oil filler cap could be the quick fix to your oil leak problem.

Worn or Damaged Parts

Damage to other parts such as the drain plug, valve gasket, oil pressure sensor or crankshaft could all lead to an oil leak.

This could mean that a part needs to be replaced by an expert mechanic to stop the leak.

A professional garage in Winchester like Williams Garage will find the source of the oil leak and fix the problem for you.

Timely replacements of any worn parts or oil as well as regular vehicle inspections can help you to prevent engine damage and increased repair costs.
