Buy INFINITI JX35 Engine Crankshaft Seals

The engine crankshaft seal, also known as the main seal or crank seal, plays a vital role in maintaining engine integrity. It prevents engine oil from leaking where the crankshaft exits the engine block, ensuring proper lubrication of internal components. By keeping the oil contained, the seal helps maintain optimal engine performance and prevents contaminants from entering the engine.

A failing crankshaft seal can exhibit several signs:

Oil Leaks: Visible oil spots beneath the vehicle, especially near the engine's front or rear, may indicate a compromised seal.
Oil Spray Under the Hood: Oil may be flung around the engine compartment due to the crankshaft's rotation.
Burning Oil Smell: Leaking oil contacting hot engine parts can produce a noticeable odor.
Low Oil Levels: Frequent drops in oil levels despite regular top-ups suggest a possible seal issue.

Several factors can contribute to crankshaft seal deterioration:

Age and Wear: Over time, seals can become brittle and lose their effectiveness.
Heat Exposure: Excessive engine heat can cause the seal material to harden or crack.
Contaminants: Dirt and debris can wear down the seal surface.
Improper Installation: Incorrect fitting can damage the seal or cause misalignment.

Proper maintenance can extend the life of the crankshaft seal:

Regular Oil Changes: Clean oil reduces wear on engine components and seals.
Monitor Engine Temperature: Keeping the cooling system in good condition prevents overheating that can damage seals.
Inspect for Leaks: Periodically check the engine area and under the vehicle for signs of oil leakage.
Use High-Quality Oil: Premium oils often contain additives that help preserve seal materials.

Replacing a crankshaft seal requires careful attention:

Professional Assistance: Due to the seal's location, consider having a qualified mechanic perform the replacement.
Quality Parts: Use seals made from durable materials suitable for your engine type.
Proper Tools: Specialized tools may be necessary to remove and install the seal without causing damage.
Follow Manufacturer Guidelines: Adhering to recommended procedures ensures a correct fit and longevity.

Addressing a faulty crankshaft seal promptly is crucial:

Prevent Engine Damage: Oil leaks can lead to insufficient lubrication, causing excessive wear or engine failure.
Avoid Safety Hazards: Leaking oil increases the risk of engine fires or loss of vehicle control if oil reaches tires or brakes.
Maintain Performance: Ensuring the seal is in good condition helps the engine run smoothly and efficiently.
Environmental Responsibility: Fixing leaks prevents oil from contaminating roads and the environment.
