How do you fix a rear main seal leak? The short answer is, you don’t. Fixing a rear main seal leak is something that in most cases is left to the professionals unless you’ve got a garage full of lots of fancy specialty tools and have lots of free time to spend getting the motor pulled out of your car. Why is fixing a rear main seal leak so difficult? Location, location, location! Since the rear main seal is at the back of the motor, the transmission has to be removed to replace it. Removing the transmission is always an expensive job and often necessitates other repairs to be done as well, which continues to drive the cost up. To find out why fixing a rear main seal leak is so expensive, join me in the garage where we’ll talk through fixing a rear main seal.

Options for Fixing a Rear Main Seal Leak

  1. Let It Leak
  2. Replace the Seal
  3. Restore the Seal

Let It Leak

Like any problem with your vehicle, you can ignore it and hope it goes away. Depending on how big the leak is, if you ignore a rear main seal leak, it will probably go away pretty quickly. The reason it will go away quickly is because your engine will run out of oil and it won’t leak anymore! Besides being leak free, your engine probably won’t be running for more than a few minutes either, as oil is the lifeblood of your engine and without lubrication, it will quickly seize. A rear main seal leak can lower the oil level in your engine very quickly. Even if you refill your oil level often, the leak will make a huge mess and often can cause oil to get onto your exhaust where it will burn.

Replace the Seal

The best option for your vehicle to keep it running safely is to replace the leaking rear main seal. A new seal will keep all your engine oil where it’s supposed to be so your car can run safely. Our recommendation would be to call a few local mechanics and ask them for an estimate on replacing the rear main seal in your car. The costs might vary widely based on the work they want to do along with replacing the rear main seal, so make sure you fully understand the estimates you get so you can compare apples to apples.
