With a strong commitment to precision, durability, and value, URO Parts ensures each part meets the highest standards. For reliable and cost-effective replacement components, URO Parts is the go-to choice.

The main reason all of the VANOS units will eventually fail is because the material used for the sealing rings from the factory is not designed for that type of environment. When this happens the only option that BMW leaves you with is buying a new and expensive VANOS unit with the same sealing rings that failed in your original unit.

The VANOS system found in BMW engines is a great feature (when it’s working properly), keeping your power curve smooth and responsive especially in lower to mid RPM range. What usually goes unnoticed is the gradual loss of power within this range as the vehicle's age due to slowly failing seals within the VANOS unit. The way the VANOS system works is based off of oil pressure triggered by a solenoid that allows for a small range of timing degree adjustment, this is where the power curve is affected. When the seals begin to fail (all of them do) there is less pressure to advance the timing reducing the power in that low to mid range. Because this happens slowly it's very hard to notice a difference until you refresh your VANOS unit, then you easily realize the response you've been missing.

There are a number of symptoms that will plague your car as a result of these failing seals such as erratic idle, engine hesitation, stalling, and increased fuel consumption to name a few. If you've been chasing down any of these symptoms with no fix then this could be your issue.

While you're replacing the seals in your VANOS unit it a good time to install anti-rattle spacers to tighten up the gaps in your stock assembly and get rid of that noisy VANOS clatter.

Seals & O-rings:

The seals  were the main focus of this project since the OE units are built with Buna-N rubber o-rings instead of the ECS supplied Viton rubber o-rings. The Buna-N material quickly hardens from the heat and chemical exposure within the engine, where the Viton is significantly more resistant to these chemicals. This knowledge was also used when it came to the commonly failed o-rings found on the VANOS seal plate, replaced at the solenoid.

Rattle Repair:

When it comes to the VANOS rattle this is commonly described as "marbles in a can", and can be heard throughout the different RPM ranges depending on the engine. These upgraded rings and washers are precision ground from hardened steel to resist wear and deformation keeping your VANOS rattle free. The rattle repair tools are designed specifically for this VANOS anti-rattle repair, design from hardened steel to stand up to the job. Designed to perfectly follow the splines of the shaft for a tight grip when applying the necessary torque to disassemble & reassemble the VANOS transfer gear. The keyed socket was designed with the intent to use a "common" wrench so this can be completed at home in your garage.    

When Servicing your VANOS unit we recommend getting everything you need to replace on the way to service which includes an oil change and valve cover gasket set. Fresh oil and gaskets is the best way to start off a fresh rebuild of any kind giving you the maximum performance of your freshly serviced components.

BMW E39 M5 S62 ECS VANOS Seal Kit

Revitalize your BMW E39 M5 S62 engine with the ECS VANOS Seal Kit, designed to restore peak performance and eliminate common Vanos system issues. Over time, the original seals in the Vanos units can harden and wear, leading to reduced hydraulic pressure and compromised cam timing control. Symptoms such as cold start rattle, erratic idle, and decreased torque output are common indicators of failing seals. ECS Tuning offers a cost-effective solution with their precision-engineered seal kit, crafted to OEM standards for reliability and durability.

Key Benefits:

• Rebuilds Vanos units to eliminate performance issues
• Precision-engineered seals ensure optimal cam timing control
• DIY-friendly with detailed installation guide for professional results
• Includes bronze impregnated Teflon seals and 70A Viton backing o-ring for enhanced durability and chemical resistance

Our Vanos seals were engineered in-house and precision machined to exacting tolerances to restore the original performance of the Vanos units.

Bronze impregnated Teflon seal for durable dynamic sealing.
70A Viton backing o-ring for extended chemical resistance, removing the OE failure point.

If you're not sure if your Vanos seals are bad then the only question you need to answer is if you've replaced them. Every unit from the factory came with the same failure prone o-rings and seals, even the re-manufactured units you can still get today. The only real fix is by replacing the seals and o-rings with material that is built to last in the oiled, extreme temperature environment found in these kits. 

A premium product replacement with easy to follow instructions makes rebuilding your Vanos unit a must. Even thought the power loss is barely felt it's the opposite result once you replace the seals, every car that gets rebuilt ends up wowing the customer and all of them saying they didn't realize what they lost. 

There are a number of symptoms that will plague your car as a result of these failing seals such as erratic idle, engine hesitation, stalling, and increased fuel consumption to name a few. If you've been chasing down any of these symptoms with no fix then this could be your issue.

The timing chain tensioner from the 1995 E36 M3 is a great upgrade for other Motorsport models - 1988-1991 E30 M3 and 1989-1995 E34 M5! This tensioner virtually eliminates the cold start-up engine rattle so common with the S14 and S38 engines. It makes the whole engine quieter and smoother. Any new tensioner will accomplish that but the S50 tensioner has several new features that make it superior to the original design. This unit also has a internally loaded spring, so installation is much easier than the old style tensioner (no need to squeeze the spring and hold it while installing). Includes oil seal ring (not pictured).
