Frequently Asked Questions

Q: What is the primary function of a crankshaft oil seal?

The crankshaft oil seal prevents engine oil from leaking out of the crankcase while allowing the crankshaft to rotate freely, ensuring proper lubrication and engine health.

Q: Why are PTFE and ACM materials used in these seals?

These materials are chosen for their exceptional resistance to high temperatures, chemical degradation from engine oil, and their ability to maintain a tight seal under pressure.

Q: How can I tell if my crankshaft seal is failing?

Common signs include visible oil puddles under the vehicle, a noticeable drop in oil levels between services, and oil residue around the transmission side of the engine.

Q: Is a professional installation required for the 038103171 seal?

Yes, we strongly recommend installation by a qualified mechanic to ensure the seal is seated correctly and the mounting sleeve/flange are properly aligned.

Q: Can a leaking crankshaft seal affect fuel efficiency?

Indirectly, yes. Oil leaks can lead to poor lubrication and internal friction, which reduces engine efficiency and can negatively impact fuel consumption.

Q: Are these seals compatible with multiple car brands?

Yes, this specific model is designed for compatibility with several major brands including Audi, BMW, Mercedes-Benz, VW, and others. Please check the OE number for exact fitment.
