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!

      If you are experiencing a leak and you are not quite sure where the leak is coming from, the BlueDevil Oil Stop Leak (https://store.gobdp.com/oil-stop-leak-49499/) would be your best bet. The Oil Stop Leak is a universal application, and would be able to treat any of the rubber seals/gaskets in the fluid oil system. The best advice in regards to keeping the vehicle in good running condition would be to make sure the vehicle is being serviced regularly and getting oil changes at the recommended intervals.

      Thank you!

    2. I have a 2006 Chrysler it’s been parked for a few days ! Came home from work an there is full of oil under my car from the engine ! Can u please give me an idea of what to do ! I’m scared to drive it to bring it to someone to look at it ! I just bought the car . Thanks

      1. Taylor-

        Thank you for asking about your Chrysler. Are you able to locate where the leak is coming from? If you haven’t done so already, you may want to check the oil level to give yourself an idea of how much oil has been lost. If needed, top it off with oil and we would recommend taking it into a certified ASE mechanic for a proper diagnosis.

        Thank you!

  2. I have a oil leak on the drivers side of my 2011cheverloet Cruze put a new value cover gasket on but still is leaking from somewhere can’t find it where it is coming from

    1. I had the same issue. I replaced the gasket and valve cover and no leaks. The valve cover itself could’ve cracked or something.

  3. I recently got a 2001 VW Passat, tonight I put about half a quart of oil in and in under 2 min all the oil i had just put in was on the ground beneath it. I don’t know much about cars so I’m not really sure where to start. But it is something I would like to try to fix myself if possible.

    1. Taylor-

      Thank you for asking about your Volkswagen Passat. Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

      Thank you!

    2. My undercarriage bottomed out pretty hard when i hit a deep pothole in a local store parking lot (’99’ buick regal GS). I immediately got out the car and looked to see if anything was damaged. After seeing no damage, no flat tires, no bent rims, nothing hanging loose, I got back into the car and headed home. On the way home my car stopped 3 times, but immediately started back up when i turned the key, yet no oil or check engine light’s ever appeared on the dash. About 2 block’s from home i started to hear a loud, vibrating, rattling noise coming from the engine. After about 15 miles i pulled up at home, got out the car again to check it out. The whole front of the undercarriage was moist with what it looked like to be oil. I decided to try and start the car, nothing. After a few failed attempts i gave it a jump and it started, Only to die again 5 minutes later. I jumped it again, it started, died 5 minutes later, still no warning lights appeared on the dash. Why didn’t my oil or engine lights come on? What exactly caused the oil leak? Pretty sure my engine is toast i poured some Lucas oil in it the next day but it’s still the same. Do you have any answers for me?

        Thank you for asking about your Buick Regal. After checking the oil level, does it appear you have lost a lot of oil? Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

        Thank you!

  4. I have a 2014 Chevy cruz, and the oil leaks more noticeably on an incline park, and it’s only on one side of the engine? What could be causing it?

    1. Claire-

      Thank you for asking about your Chevy Cruze. The location of the leak would be difficult to say, not being at the vehicle. Based on your description, we recommend using the BlueDevil Oil Stop Leak. You should expect to start seeing results after approximately 100-200 miles of driving.

      Thank you!

      The BlueDevil Oil Stop Leak would be able to treat a leaking valve seal. As long as the leak isn’t more than a seep or light drip, you would be a good candidate for the product. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!

      Thank you for asking about your Subaru Tribeca. It would be difficult to say where the leak is coming from, not being at the vehicle. It could be valve cover gaskets, timing chain gasket or even the oil pan gasket. As long as you are not losing oil too quickly, you would be a good candidate for the BlueDevil Oil Stop Leak. You should expect to start seeing results after approximately 100-200 miles of driving.

      Thank you!

  5. I have a 2007 LEXUS ls 460. It runs great. However I’m losing all oil 9 quarts, in less than 2000 miles. None on ground. Gas attendant said maybe it’s leaking inside engine. How much trouble am I in.

    1. Gilbert-

      Thank you for asking about your Lexus LS460. Losing 9 quarts of oil in such a short span sounds like it would be an extreme leak. Have you gotten any engine codes or warning indicators on the dash? It doesn’t seem like you are experiencing any issues with vehicle performance, which would also be odd based on the amount and how quickly you are losing oil. We’d recommend bringing the vehicle into a shop for a proper diagnosis.

      Thank you!

  6. I have an 06 Ford Fusion I just bought with 117000 miles on it. It leaks in three places. Two are near the center of the hood and I’m pretty sure they’re transmission leaks. One is at the very front of the engine and after two days of sitting is just a wet spot a little bigger than a quarter. Would stop leak work for this leak?

    1. Brett-

      Thank you for asking about your Ford Fusion. Yes, the BlueDevil Oil Stop Leak would treat the leak you’ve described. Also, we do manufacture the BlueDevil Transmission Sealer to help stop the leaks coming from the transmission. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!

  7. Hi. I have a 2004 corolla le & I found it’s leaking both black oil and light brown oil. It was obvious the black oil was motor oil, but can motor oil leak out 2 different colors? The oil level is good & it’s not dripping much.

    1. Ashley-

      Thank you for asking about your Toyota Corolla. Motor oil will appear between a thin light brown liquid to a thick dark black, depending on its age. Is the leak occurring from around the same location? Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

      Thank you!

  8. I have a small oil leak on the passenger side of my Toyota Camry.. we replaced the gasket but it still is leaking. So what could be the issue?

    1. Rahman-

      Thank you for asking about your Toyota Camry. Is it possible that you are losing oil from a different location other than the gasket that was replaced? If so, we recommend using the BlueDevil Oil Stop Leak. You should expect to start seeing results after approximately 100-200 miles of driving.

      Thank you!
