Key Features

• Premium-grade valve stem oil seal set
• Controls lubrication at the valve stem to reduce oil entry into the combustion chamber

Detailed Description

DJ Rock VSS315 is designed for engines that need precise valve stem sealing to maintain combustion chamber cleanliness and stable oil control. The seal design uses durable elastomer materials selected for resistance to heat, oil exposure, and chemical breakdown, while the metal shell provides structural support and corrosion resistance. An integrated spring helps maintain uniform pressure around the valve stem for consistent sealing performance. This makes the VSS315 a practical choice for Saturn L300, Cadillac CTS, and Saab 9-5 service work where valve stem seal wear can affect engine operation.

What It Helps Fix

• Oil consumption caused by worn valve stem seals
• Blue exhaust smoke after startup or deceleration
• Oil fouling on spark plugs
• Loss of sealing at the valve stem during top-end service
• Compression chamber contamination from oil leakage

Installation Notes and Tips

Install during cylinder head service or a complete rebuild when the valves are accessible. Inspect valve guides, valve stems, and related top-end components before assembly, and verify that the seals seat fully on the guide and stem. Clean mating surfaces and follow the engine service manual for the correct installation procedure.
