The **Audi 079109003DS engine cylinder head assembly (2014 2015 models, including the RS7, RS6, and CRD/CRDB variants)** represents a critical high-performance component engineered for the 5.0-liter V10 biturbo gasoline (RS7) and 4.2-liter V8 turbocharged diesel (CRD/CRDB) powertrains found in Audi s most exhilarating and demanding models. Designed to withstand extreme thermal and mechanical stresses, this precision-machined cylinder head is a masterpiece of automotive engineering, featuring a robust **aluminum alloy construction** reinforced with high-strength fasteners and advanced cooling channels to dissipate the immense heat generated by forced induction and high-output combustion. The assembly incorporates **dual overhead camshafts per bank**, each driving a set of **four valves per cylinder** (intake and exhaust) via a sophisticated valve train system, ensuring optimal airflow and combustion efficiency for peak performance. For the **RS7 s 5.0L V10**, the cylinder head is equipped with **direct and port fuel injection**, high-pressure turbocharging, and variable valve timing (VVT) to maximize torque delivery and responsiveness, while the **CRD/CRDB s 4.2L V8** benefits from a **common-rail diesel system**, precise fuel atomization, and turbocharged air management to achieve its legendary power and torque curves. Both configurations emphasize **minimal friction and maximum durability**, with features like **hydraulic lash adjusters** for consistent valve clearance and **integrated oil and coolant passages** to maintain critical operating temperatures. Whether installed in the **RS7 s 612-horsepower gasoline beast** or the **RS6/CRDB s 500 lb-ft diesel torque monster**, this cylinder head is a testament to Audi s commitment to performance, reliability, and cutting-edge engineering essential for enthusiasts seeking to restore, modify, or replace a worn or damaged component in one of the brand s most iconic high-performance engines.

### **Pros and Cons of Buying Used Audi Cylinder Heads and Camshafts (Part Numbers: 079109003DS, 2014 2015 RS7/RS6 2.9L/3.0L CRD/CRDB, Left-Hand Side, Cylinders 5 8)**

#### **Pros:**

1. **Performance Potential** These components are part of Audi s high-performance diesel engines (V6 2.9L TDI or V8 3.0L TDI), which are known for strong torque and reliability when properly maintained. Upgrading or replacing worn camshafts and cylinder heads can restore power output, improve throttle response, and enhance overall engine efficiency.

2. **Aftermarket Support** The 2.9L and 3.0L TDI engines have a dedicated aftermarket community, including tuners, remanufacturers, and performance shops that specialize in these parts. This means you ll find compatible upgrades, gaskets, seals, and supporting hardware more easily than for less common Audi engines.

3. **Remanufactured Options Available** Many reputable suppliers (e.g., **Audi Specialty Auto Parts, JE Crowe, or local diesel specialists**) offer remanufactured cylinder heads and camshafts that are rebuilt to factory or even upgraded specifications. This can be more cost-effective than buying new OEM parts.

4. **Compatibility with Modifications** If you re running a turbo upgrade, larger injectors, or a performance tune, these components are critical for handling increased power. Stock camshafts and heads may not be sufficient for high-power builds, making replacements a necessary investment.

5. **Long-Term Reliability (When Properly Serviced)** The 2.9L and 3.0L TDI engines are robust when maintained correctly. Replacing worn components can extend the engine s lifespan, prevent catastrophic failure, and reduce the risk of oil consumption or misfires.

6. **Easier to Source Than Full Engines** Buying individual cylinder heads and camshafts is often cheaper than purchasing a complete engine swap, especially if you re only targeting specific issues (e.g., carbon buildup, worn valve seats, or camshaft wear).

7. **Potential for DIY Installation** With the right tools and mechanical knowledge, these parts can be installed at home, saving labor costs. However, cylinder head work requires precision (sealing, valve lash adjustments, and torque specifications), so inexperienced DIYers may need professional help.

---

#### **Cons:**

1. **High Upfront Cost** Even remanufactured parts for these high-performance Audi engines can be expensive. A full set of cylinder heads (including gaskets, bolts, and seals) may cost **$1,500 $3,500 **, while camshafts alone can range from **$500 $1,200 per pair**. Labor for installation (if outsourced) adds significantly to the total cost.

2. **Complex Installation** Cylinder head work is labor-intensive and requires:

- Proper cleaning (ultrasonic bath for carbon removal).

- Valve grinding or replacement if worn.

- Correct torque sequencing on bolts (Audi uses specific patterns and torque specs to prevent warping).

- Camshaft alignment and valve lash adjustments.

- Rebuilding or replacing seals, gaskets, and oil passages.

**Mistakes here can lead to oil leaks, misfires, or even engine damage.**

3. **Risk of Counterfeit or Poor-Quality Parts** The aftermarket for Audi diesel parts has seen instances of counterfeit or substandard remanufactured components. Always buy from **reputable suppliers with warranties** (e.g., **Audi Specialty Auto Parts, JE Crowe, or trusted local diesel shops**) to avoid issues like:

- Improperly machined valve seats.

- Weakened cylinder head castings.

- Camshafts with incorrect profiles or wear.

4. **Potential for Hidden Damage** If the cylinder heads or camshafts were removed due to an underlying issue (e.g., cracked head, warped deck, or internal engine damage), simply replacing them may not solve the problem. A **full engine inspection** (compression test, leak-down test, and inspection for warping or cracks) is essential before purchasing.

5. **Limited Availability of OEM Parts** While remanufactured parts exist, ** genuine Audi OEM replacements** (if needed) can be hard to source and may require ordering from Europe or Audi s official parts department, increasing lead times and costs.

6. **Tuning and Supporting Modifications Required** Simply swapping in new parts won t guarantee improved performance. If you re pushing power beyond stock levels, you ll need:

- A **performance tune** (e.g., from **AEM, Haltech, or Audi-specific tuners**).

- Upgraded injectors, turbo, and fuel system components.

- Proper cooling and lubrication upgrades (e.g., larger radiator, upgraded oil cooler).

**Skipping these can lead to engine damage.**

7. **Time-Consuming Process** Even with remanufactured parts, the entire job (disassembly, machining, installation, and break-in) can take **50 100 hours** of labor if done professionally. DIYers may spend even more time due to learning curves and potential mistakes.

8. **Warranty and Liability Risks** If the parts fail shortly after installation (due to poor remanufacturing or installation errors), you may be left with a non-running engine and no warranty coverage if you didn t purchase from a reputable supplier.

---

### **Key Considerations Before Purchasing:**

1. **Diagnose the Root Cause** Before buying parts, confirm that the issue is **not** something else (e.g., failing injectors, turbo wastegate failure, or internal engine damage). A **compression test, leak-down test, and visual inspection** are critical.

2. **Choose the Right Parts:**

- **Remanufactured vs. New:** Remanufactured is usually sufficient unless you re building for extreme power.

- **Stock vs. Upgraded Camshafts:** Stock camshafts are fine for stock or mild builds. For performance, consider **aftermarket options** (e.g., **BMS, JE Crowe, or Audi Sport camshafts**) for better lift/duration.

- **Cylinder Head Material:** The 2.9L/3.0L TDI heads are aluminum, which is prone to warping. Ensure they re **machined flat** if reused.

3. **Find a Trusted Supplier** Avoid cheap eBay or Craigslist deals. Stick to:

- **Audi Specialty Auto Parts**

- **JE Crowe**

- **Local diesel performance shops** (ask for references)

- **Reputable remanufacturers** (e.g., **Performance Diesel, Audi Diesel Specialists**)

4. **Budget for Supporting Modifications** If you re pushing power, plan for:

- **Fuel system upgrades** (high-pressure pump, injectors).

- **Turbo and intercooler upgrades** (if stock turbo is limiting).

- **Cooling and lubrication upgrades** (larger radiator, upgraded oil cooler).

- **A performance tune** (mandatory for safe operation).

5. **Plan for Professional Installation** Unless you re highly experienced, **have a trusted mechanic** handle the job to avoid costly mistakes.

---

### **Final Recommendation:** **Buy these parts if:**

You have a **diagnosed issue** (e.g., carbon buildup, worn camshafts, or valve seat wear) and need a **cost-effective solution** to restore performance.

You re **building a high-performance diesel** and need **reliable, high-quality components** to handle increased power.

You have **access to a reputable supplier** and are prepared for the **labor-intensive installation process**.

You re **budgeting for supporting modifications** (tune, injectors, turbo, etc.) to ensure safe operation.

**Avoid buying if:**

You re **unsure of the exact problem** and haven t performed diagnostics.

You re **not prepared for the cost** (parts labor supporting mods can exceed **$3,000 $6,000 **).

You **lack mechanical experience** and can t afford professional installation.

You re buying from an **untrusted source** (risk of counterfeit or poor-quality parts).

---

### **Best Approach:**

1. **Get a full engine diagnosis** (compression test, leak-down, visual inspection).

2. **Purchase remanufactured parts from a trusted supplier** (e.g., **Audi Specialty Auto Parts**).

3. **Consider upgrading camshafts** if building for performance (e.g., **JE Crowe or BMS profiles**).

4. **Have a mechanic perform the installation** (or be prepared for a steep learning curve).

5. **Plan for a performance tune and supporting mods** if increasing power beyond stock.

**Conclusion:** These parts are a **wise investment** for restoring or enhancing the performance of your 2014 2015 RS7/RS6 diesel engine, but they require **careful planning, proper diagnostics, and either mechanical skill or professional labor**.
