Fluid leakage in cars and how to identify them?

Are you seeing oil leaking from the top of your engine? Or are you smelling burning oil? The most likely cause is damage to the valve cover gasket. The first thing you should do is check your oil as you may have been losing oil for a while and it is never good to drive the vehicle if it is low on oil.

Valve Cover Gasket Leak Inspection

Commonly, the engine valve cover is the top most part of an engine and is labeled with either the name of the manufacturer or the size of the engine. A valve cover gasket is put in place because the metal of the valve cover does not seal tightly enough against the metal of the top of the engine. The cork material or rubber of the valve cover gasket safeguards a good seal, and helps stop oil from spilling out of the top of the engine.



Valve cover gaskets unusually last the life of a vehicle and must be monitored at the time of every service. For vehicles with four-cylinder engines, checking for oil around the valve cover is especially important because of an increased chance that oil could leak into spark plug tubes, causing misfires.

Oil leaks can cause damage to any engine and must immediately be dealt with.

Common causes of valve cover gasket leaks

  • Blown Valve Cover Gaskets: The tremendous heat an engine produces can result in valve cover gaskets to become brittle and break down over time.
  • Damaged Valve Covers: A mechanic must also inspect your valve cover(s) to make sure they are still intact when replacing your valve cover gasket. Damage to a valve cover could also result to an oil leak.

What to expect during a valve cover gasket leak service

certified mechanic will come to your home or office to pinpoint the cause of the oil leak and confirm that the valve cover gasket requires replacement. The mechanic will then run a detailed inspection report outlining the cause of the leak and the cost of any repairs that need to be made.

Engine Oil Leak Diagnostic

The Engine Oil in a car has many functions, and one of these functions is removing the deposits of sludge and gunk in the engine keeping it clean. Engine oil that is unused has an amber color; however, it changes to black over time after being exposed to heat and dirt from the engine. Engine oil is critical for the proper function of your engine and an engine oil leak should be addressed right away to avoid engine damage.



To check for engine oil leaks keep a close eye on your oil dipstick. If the level drops over time, you’re losing oil. While driving, check and see if blue smoke is coming from the tailpipe. Blue smoke means oil might be leaking into the engine itself. After a drive, you may notice a burning oil smell. This could mean oil is leaking onto hot components of the engine itself. Lastly, check for the classic oil stains or puddle under the engine compartment, especially after it’s been sitting overnight.


Finding a puddle under the engine is usually the sign of a leak. If the liquid is red it’s probably transmission fluid. If the liquid is green or orange and has a sweet smell, coolant is the culprit. Brown fluid will indicate an engine oil leak.
