Review BMW Genuine Crankshaft Seal fits 760LI 2010–2015

The **73315GRWH crankshaft seal** is a precision-engineered aftermarket replacement part specifically designed to restore optimal performance and longevity to the engine bay of your **2010 2015 BMW 760Li (N63 V8)**. Crafted to meet or exceed OEM specifications, this high-quality seal is meticulously manufactured using **high-temperature-resistant elastomers and reinforced synthetic materials**, ensuring durability under the demanding conditions of a high-performance BMW engine. The seal features a **perfectly contoured lip design** that guarantees a secure, oil-tight fit against the crankshaft, preventing leaks that could compromise engine efficiency or lead to costly internal damage. Ideal for applications requiring both reliability and performance, this seal is built to withstand the thermal and mechanical stresses of the **N63 twin-turbo V8**, which is known for its aggressive power delivery and high-revving nature. Whether you're addressing a leaking crankshaft seal as part of a routine maintenance schedule or replacing a worn component after extended use, this aftermarket seal provides a seamless alternative to OEM parts, often at a more affordable price without compromising on quality. Its compatibility with the **2011, 2012, 2013, 2014, and 2015 model years** of the 760Li ensures a straightforward installation process, allowing for a quick and hassle-free upgrade that restores engine integrity and extends the lifespan of your vehicle s critical components.

### **Pros and Cons of buying a 73315GRWH Crankshaft Seal for 2010 2015 BMW 760Li (2011 2014 Models)**

1. **OEM Quality and Fitment** The **73315GRWH** is a genuine BMW part, meaning it is designed specifically for your vehicle s engine (N63 V12). This ensures proper fitment, sealing, and compatibility with the crankshaft s dimensions and mounting points. Aftermarket alternatives may not match the precision of an OEM seal, potentially leading to leaks or premature failure.

2. **Reliability and Durability** BMW s OEM components are built to meet strict quality standards, reducing the risk of early wear or failure compared to cheaper third-party seals. This is particularly important for high-performance engines like the N63, which operate under high stress and heat.

3. **Warranty Coverage** Purchasing from an authorized BMW dealer or a reputable supplier often includes a warranty (typically 12 24 months). This provides peace of mind in case the seal fails shortly after installation. Aftermarket parts may not offer the same level of warranty protection.

4. **Prevents Engine Damage** A failing crankshaft seal can lead to oil leaks, which if left unchecked can contaminate the timing chain, bearings, or other critical components. Replacing it proactively avoids costly engine damage down the line.

5. **Professional Installation Support** When buying from a dealer or a trusted mechanic, you often gain access to expert installation services. Proper sealing requires precise alignment and torque specifications, which are easier to achieve with professional help.

6. **Long-Term Cost Efficiency** While the upfront cost is higher than aftermarket options, the longevity and reliability of an OEM seal can make it more cost-effective in the long run, especially for high-mileage or performance-oriented vehicles.

7. **Compatibility with Modifications** If your 760Li has been modified (e.g., forced induction, upgraded oil systems), an OEM seal ensures it meets the original engine s specifications, reducing the risk of leaks or compatibility issues.

1. **Higher Upfront Cost** OEM parts are significantly more expensive than aftermarket alternatives. For example, while an aftermarket crankshaft seal might cost **$50 $100**, the **73315GRWH** can range from **$150 $300 **, depending on the supplier. This can be a barrier for DIYers or those on a tight budget.

2. **Limited Availability Outside Dealers** Authentic BMW parts are not always readily available at local auto parts stores. You may need to order from an online dealer (e.g., BMW Specialty Parts, RockAuto, or eBay), which can involve shipping delays or counterfeit risks if not purchased from a verified source.

3. **Potential for Overpricing** Some dealers or online sellers mark up OEM parts excessively, especially for older model years. It s important to compare prices across multiple sources to ensure you re getting a fair deal.

4. **Installation Complexity** Replacing a crankshaft seal requires removing the oil pan, timing components, and sometimes the crankshaft pulley. This is a labor-intensive job that may not be suitable for inexperienced DIYers. Professional installation adds to the total cost.

5. **Risk of Counterfeit Parts** If purchasing from untrusted sources (e.g., unverified eBay sellers or gray-market suppliers), there s a chance of receiving a fake or low-quality seal. Always verify the seller s reputation and part authenticity.

6. **Time-Consuming Process** The job can take **6 12 hours** for a professional mechanic, depending on the vehicle s condition and any additional repairs needed (e.g., replacing gaskets, cleaning the crankshaft). This downtime can be inconvenient for owners who rely on their vehicle.

7. **Potential for Additional Repairs** If the seal has been leaking for some time, oil may have contaminated other components (e.g., timing chain, bearings, or oil passages). Inspecting and addressing these issues during the seal replacement can increase the total repair cost.

### **Conclusion**

The **73315GRWH crankshaft seal** is the **best choice** for your 2010 2015 BMW 760Li (N63 engine) if you prioritize **reliability, longevity, and compatibility**. While it comes with a higher price tag and complexity, the risks of using a subpar aftermarket seal such as leaks, engine damage, or premature failure far outweigh the benefits. For owners who value their vehicle s performance and longevity, investing in an OEM seal is justified.

However, if budget is a major concern, **high-quality aftermarket alternatives** (e.g., Fel-Pro, Sealed Power, or Mann) can be a cost-effective compromise, provided they are from reputable brands with good reviews. Always ensure the aftermarket seal is **direct-fit** and designed for the N63 engine.

---

### **Recommendation**

1. **Buy from an Authorized Source** Purchase the **73315GRWH** from an **official BMW dealer** or a **trusted online retailer** (e.g., BMW Specialty Parts, RockAuto, or a verified eBay seller with positive feedback). Avoid unknown suppliers to prevent counterfeit parts.

2. **Verify Part Authenticity** If ordering online, check for **BMW part numbers, serial numbers, or holograms** to confirm it s genuine. Some dealers offer **authentication services** for OEM parts.

3. **Budget for Professional Installation** Unless you have **mechanical experience**, hire a **BMW specialist or a reputable mechanic** to handle the installation. Improper sealing can lead to leaks or damage.

4. **Inspect for Additional Repairs** If the seal has been leaking, have the mechanic **clean the crankshaft, check the timing chain, and inspect oil passages** for contamination. Addressing these issues upfront prevents future problems.

5. **Consider Aftermarket as a Backup** If the OEM part is unavailable or priced too high, **Fel-Pro 100 or Mann HHG 100** are well-regarded aftermarket alternatives that offer good performance. Ensure they are **direct-fit** for the N63 engine.

6. **Monitor for Leaks Post-Installation** After replacement, **check the oil level and for leaks** during the first few weeks. If any issues arise, address them promptly.

**Final Verdict:** For the **2011 2014 BMW 760Li (N63)**, the **73315GRWH OEM crankshaft seal** is the **best long-term solution** despite the higher cost. It ensures **proper sealing, reliability, and compatibility**, reducing the risk of engine damage. If cost is a concern, **high-quality aftermarket seals** can be a viable alternative, but always prioritize **fitment and brand reputation**.
