Common Engine Oil Leak Locations

engine oil leakHaving an engine oil leak is the kind of thing that will bother some people, but is no big deal for others.  If you have a clean new driveway, oil leaks can be extremely annoying as they leave more and more little spots in front of your house.  Also, if you do any of your own maintenance on your vehicle, having an engine oil leak be frustrating and downright messy! The first step in repairing any engine oil leak in your car is locating the leak.

The best way to locate an engine oil leak is to start by cleaning things up as best you can.  If there is lots of road gunk or old oil on your engine, it can be difficult to tell where the leak is coming from.  Once you’ve got things clean enough to see fresh oil leaking out of your engine, you can go for a drive, let your car cool then do a quick inspection looking for the location of your oil leak.  To make that inspection go fast, we’ve put together a list of the most common engine oil leak locations!

Common Engine Oil Leak Locations

  • Rear Main Seal
  • Oil Pan Gasket
  • Valve Cover Gasket
  • Timing Cover Gasket

Rear Main Seal

The rear main seal is at the back of your engine and seals where the crankshaft exits the engine to attach to the flywheel.  This seal is notorious for leaking on vehicles that don’t get used often or don’t get regular oil changes. If you’ve got a rear main seal leak, check out our article about why rear main seals leak and how to get it fixed!

Oil Pan Gasket

Another common engine oil leak location is your oil pan gasket.  This gasket can leak over time due to infrequent oil changes, or even just normal use.  This gasket seals between your oil pan and your engine block. This gasket is thin and long and your oil pan is made of thin metal that expands and contracts significantly with engine operation.  On some vehicles with no obstructions to the oil pan gasket is a quick repair. On other vehicles such as 4 wheel drive vehicles or vehicles with transversely mounted V6 engines, there can be lots of components under the oil pan making it very difficult to remove.  If you can’t easily get to your oil pan gasket, consider using BlueDevil Oil Stop Leak to stop the leak by revitalizing the gasket!

Valve Cover Gasket

Your valve cover or covers are very similar in construction to your oil pan meaning they are long and made of thin metal so they are subject to the same leaking problems.  On many vehicles, the valve covers are easily accessible as they are right on top of your engine so replacing the gaskets is relatively easy. On some 6 cylinder engines, the intake manifold may cover one of the valve covers.  If that is the case, you can use BlueDevil Oil Stop Leak to seal the leak!

Timing Cover Gasket

The timing cover is at the front of your engine if your engine has a timing chain.  The cover shields the timing components like the chain and gears on the crankshaft and crankshaft.  The timing system is splash lubricated so leaks from the timing cover gasket are often slow leaks but they can make a mess as they leak out around your engine’s drive belt and accessories.  Replacing the timing cover gasket is always an expensive job as you’ve got to remove lots of other pieces before you get to the timing cover. BlueDevil Oil Stop Leak is again a great option to stop leaks in your timing cover gasket to save you money!
