Does My Vehicle Have a Main Seal Leak?

Updated: 11/09/2023

One of the most common automotive problems is a main seal leak. Located near the transmission, this part keeps oil in the crankcase and flowing to the various engine components. Often, a car's oil consumption is hidden by other parts, but a rear main seal leak is very obvious. In addition to oil spillage, your vehicle may also have other issues such as a cracked head gasket or a broken main gasket.

How Does A Main Seal Leak Happen In A Car?

In some cases, a main seal leak can occur from a defective rear seal. The leak can be asymptomatic until the car reaches a certain temperature. If it is a slow leak, the problem is most likely at night or after parking. If you notice oil stains, it may be a sign that your car is losing oil. However, if you notice a leaking main gasket, it's better to get a professional to diagnose it.

How Do You Know If Your Car Has A Seal Leak?

The rear main seal is typically driven into the engine's rear cover recess. Once installed, you can't see the seals, so you need to get an expert to diagnose the main seal leak problem. In some cases, oil accumulation may be a sign of a leak. If the oil light comes on after changing the oil, it's likely that you're dealing with a leak.

Do You Need To Go To A Mechanic If You Have A Seal Leak?

A rear main seal leak can be a major problem for your vehicle. It can result in serious damage to your car's engine, which is why it's important to have it repaired as soon as possible. If you think the oil level is too low, you should stop driving the vehicle. The rear main seal can be difficult to repair because it's located in a difficult-to-access location. You may have to remove the engine, transmission, and oil pan to get access to it.

Is A Main Seal Leak Bad For My Car?

Rear main seals are difficult to inspect, but they are vital to the functioning of the car. An oil leak can cause your car to lose engine oil, and it can cause a costly repair bill. In addition to oil leaks, there are other symptoms that may indicate the presence of a main-sealed rear main seal leak. An underbody oil warning light may also indicate a rear-main seal problem.

If you suspect a rear-main seal leak, you should take your vehicle to a professional technician as soon as possible. The oil leak in the front of the transmission is a sign of a rear-main seal failure. The fluid is likely leaking from the front main-seal. If the front main-sealed rear-main seal leak is present, you should clean the engine and check for the leaks.
