The VR6 engine, known for its smooth power delivery, can sometimes develop an annoying rattle from the intake manifold. This is often caused by worn shift rod bushings. Upgrading to aftermarket Vr6 Intake Manifold bushings is a cost-effective solution to eliminate this rattle and prevent further damage.
Why Upgrade Your VR6 Intake Manifold Bushings?
The factory bushings in many VR6 engines are prone to wear. As these bushings deteriorate, they create excessive play in the shift rod, resulting in a noticeable rattling sound during acceleration and deceleration. Ignoring this issue can lead to more significant problems, including damage to the plastic intake manifold itself, requiring costly replacement.
Upgraded VR6 intake manifold bushings are typically constructed from more durable materials and designed with improved geometry for increased contact area with the manifold. This enhanced design provides a more secure fit, reducing movement and eliminating the rattle. Furthermore, the robust construction of aftermarket bushings ensures a longer lifespan compared to the OEM parts.
Choosing the Right VR6 Intake Manifold Bushings
When selecting replacement bushings, ensure compatibility with your specific VR6 engine code and model year. Common applications include:
- 2.8L 12V VR6 (AFP Engine Code): Found in 99-02 Golf/Jetta VR6 models, replacing bushings on OEM VW rod part number 021-133-653.
- 2.8L 24V VR6 (BDF Engine Code): Found in 02 and later Golf/Jetta VR6 models, replacing bushings on OEM VW rod part number 022-133-653.
- 3.2L 24V VR6: Found in all R32, 3.2L Touareg, 3.2L Eos, 3.2L A3, and 3.2L TT models, replacing bushings on OEM VW rod part number 022-133-653B.
In some cases, particularly with very early 99.5 model year VR6 engines, you may need to replace the entire shift rod along with the bushings due to a different design utilizing five bushings.
Installation and Additional Upgrades
Installing VR6 intake manifold bushings is a relatively straightforward process, often achievable with basic tools. DIY instructions are readily available online.
While addressing the bushings, consider complementary upgrades for optimal performance and longevity:
- Upgraded Billet Intake Manifold Ball: Replacing the plastic ball with a billet aluminum version improves durability and reduces wear.
- Upgraded Billet Intake Drive Unit Link: A stronger linkage minimizes flex and ensures precise movement of the intake manifold mechanism.
Preventing Future VR6 Intake Manifold Issues
Even with new bushings, it’s essential to address any existing damage to the intake manifold. If your VR6 has experienced prolonged rattling, inspect the manifold for wear or cracks. A damaged manifold should be replaced to prevent recurring problems.
By proactively upgrading your VR6 intake manifold bushings, you can eliminate annoying rattles, prevent costly repairs, and ensure the long-term health of your engine. Choosing high-quality aftermarket bushings and considering complementary upgrades will provide the best results and peace of mind.
