Frequently Asked Questions (FAQs)

1. What is the best material for a rear main seal?

Molded synthetic rubber is the material most commonly used for rear main seals. It offers proven sealing ability, excellent heat resistance and easy installation.

2. What causes a rear main seal to leak?

The most common cause of rear seal leaks is age and/or high mileage. The seal can also leak due to the vehicle being stored for an extended period of time, or from running the engine low on oil. This causes drying and hardening of the seal leading to shrinking, cracking and tearing of the rear main seal.

3. What is a rear main seal called?

An oil leak from the main seal, also known as the rear crankshaft seal, will usually drip from where the transmission connects to the engine, though it may show up elsewhere, such as on the oil pan.

4. Is crankshaft seal and rear main seal the same?

A rear main seal, or crankshaft seal as it is commonly referred to, is a big, round rubber seal between the engine and transmission. The rear seal fits snuggly around the rear of the crankshaft and keeps the engine oil from escaping.
