Complete 6.0 Powerstroke Oil Leak Repair – Oil Rail + Injector Seals in One Kit
If your 6.0 Powerstroke is hard starting, losing ICP pressure, or leaking oil under the valve covers, you’re likely dealing with worn oil rail nipple O-rings and injector seals—two of the most common failure points in the high-pressure oil system.
The SWAG Performance Oil Rail Nipple O-Ring Kit + Mahle GS33711 Injector Seal Kit gives you a complete solution, allowing you to service both the oil rail connections AND injector seals at the same time—saving labor, downtime, and repeat tear-downs.
Why This Kit Dominates Competing Options
Most kits on the market only address one issue. This setup fixes both:
✔ Premium Viton® Oil Rail O-Rings – Handles extreme heat and oil exposure
✔ Genuine Mahle GS33711 Injector Seal Kit – OE-quality injector sealing solution
✔ Complete Top-End Leak Repair – Addresses both rail and injector leak points
✔ Prevents Repeat Failures – Replace all critical seals in one service
✔ Better Value vs Competitor Kits – More coverage without overpriced bundles
What Problems This Kit Solves
- Long crank / hot no-start
- Low ICP (Injection Control Pressure)
- Rough idle or injector misfires
- Oil leaks under valve covers
- Power loss and poor throttle response
This is one of the most effective preventative and repair upgrades for any 6.0L Powerstroke.
Compatibility Disclaimer – 6.0L Powerstroke Oil Rail Nipples
Late model (2003.5–2007) oil rail nipples are not compatible with early 2003 “log style” high-pressure oil rails. Although similar in appearance, these components are engineered for different oil rail designs, internal geometries, and pressure systems. Attempting to install late model oil rail nipples into early style oil rails may result in improper seating, inadequate sealing, and high-pressure oil leaks. This can lead to engine performance issues including hard starting, loss of injection control pressure (ICP), injector misfires, and potential engine damage.
