Fel-Pro Volkswagen Jetta SS 71074-1 Engine Valve Stem Oil Seal Set

When you're rebuilding the top end of an engine, especially on vehicles like the Volkswagen Jetta, Audi A4, or Porsche Cayenne, replacing the valve stem seals is a crucial step. These small but mighty seals prevent oil from leaking down the valve guides and into the combustion chamber. If they're worn out, you'll notice blue smoke on startup or when you let off the gas, and your oil consumption will go up. This set from Fel-Pro is made to handle the real-world repair environment, meaning they're designed to seal even on surfaces that aren't perfectly smooth.

Fel-Pro engineers these seals with specific applications in mind, using the right materials and seal types—whether it's an umbrella, O-ring, or positive seal—to get the job done right. They've put in the work to validate and approve these parts through rigorous testing. Plus, they include a helpful installation tool to protect the seal's inner lip as you put it in place, which is a thoughtful touch that can save you a headache during the job.
