Introduction

Let’s talk about a little-known, but essential, part of your vehicle – the rear main seal. Not a topic on the top of your conversation list? It could be, especially if it starts causing trouble.

What is a Rear Main Seal?

The rear main seal is a circular seal mounted at the rear of an engine that stops the engine oil from leaking as it goes from the engine block to the oil pan. It’s a critical seal between the engine and transmission, and if it fails, the consequences can be quite messy.

How Much Will it Cost to Replace a Rear Main Seal in Canada?

In Canada, replacing a rear main seal typically costs between $400 and $1200. While the seal itself is relatively inexpensive (usually $30 to $80), the labour is where the cost adds up. The complexity of the repair requires several hours of work, often 4 to 6 hours, due to the need to remove either the engine or transmission to access the seal.

What are the Symptoms of a Faulty Rear Main Seal?

• Oil leaking from the rear of the engine.
• Oil spots on the ground where the vehicle is parked.
• Engine oil level decreases more rapidly than usual.

How Long Does a Rear Main Seal Last?

How Does a Rear Main Seal Become Defective?

Wear and tear is a primary cause of rear main seal failure. Over time, the seal’s material can become hard and brittle, losing its ability to keep oil inside the engine. Engine overheating, poor quality oil, and debris can also contribute to its degradation.

How Can a Faulty Rear Main Seal Affect Other Systems in the Car?

A leaking rear main seal can cause oil loss, potentially leading to engine damage due to poor lubrication. Moreover, the oil leaking onto other parts, such as the exhaust, could pose a fire risk.

While a minor leak may not cause immediate issues, driving with a faulty rear main seal isn’t advised. The risk of engine damage from oil loss and the potential fire hazard from oil leakage make it a repair you shouldn’t postpone.

How Can I Make My Rear Main Seal Last Longer?

• Regularly check and maintain your engine oil level.
