What is a front crankshaft seal?
Front crankshaft seals play a critical role in your vehicle. Positioned in front of the engine and behind the main pulley that drives the serpentine and timing belts, they ensure smooth operation and shield the undercarriage from debris and contaminants.
Constructed from robust materials like rubber or silicone, crankshaft seals are built to withstand the rigors of daily exposure to high temperatures and corrosive engine oil. However, they are susceptible to wear and tear over time.

FAQs
Here are a few common reasons why a crankshaft seal might develop a leak:
- Wear and tear of the crankshaft: Over time, the crankshaft can experience wear and tear, causing the seal to become loose and resulting in leakage.
- Damaged gaskets: Extended exposure to high temperatures can degrade the rubber in gaskets, leading to leaks.
- Cracked shell: The crankshaft seal is housed in a metal shell, and if this shell develops cracks, it can allow air and oil to mix, causing leaks.
- Foreign objects: External elements like dust, grit, or dirt entering the engine can become trapped between the seal and crankcase wall, leading to friction and eventual leakage.
Ignoring a leaking crank seal is risky. It can lead to engine damage and even total engine failure if left unaddressed.
Replacing a crankshaft seal can be a challenging task, often involving work on the engine or dealing with other intricate components of the car.
