Review MERCEDES benz Used Right Engine Cylinder Head S class 164 Ty fits 2007

The **Mercedes-Benz 210989 right engine cylinder head (M272 OM646 DE20 LA 164 TY)** is a precision-engineered component designed exclusively for the high-performance **2007 Mercedes-Benz S-Class (W221) models** equipped with the **5.5-liter V8 OM646 DE20 LA engine**, specifically the **164 TY variant**. This cylinder head is a critical part of the engine s combustion system, responsible for housing the intake and exhaust valves, spark plugs, and camshaft components, while ensuring optimal airflow, thermal management, and structural integrity under extreme operating conditions. Crafted from high-grade **cast aluminum alloy**, it is engineered to withstand the intense heat and pressure generated by the high-compression, turbocharged V8, which produces a staggering **400 horsepower and 420 lb-ft of torque** in its standard form. The **210989** designation ensures compatibility with the **right-hand side cylinder head** of the engine, which is symmetrically paired with the **210988 left-hand side counterpart**, maintaining balanced performance and longevity.

This cylinder head features a **dual overhead camshaft (DOHC) design**, with each camshaft driving four valves per cylinder (two intake and two exhaust) via **hydraulic lifters**, eliminating the need for manual adjustment and reducing maintenance requirements. The **intake ports** are meticulously contoured to maximize airflow efficiency, while the **exhaust ports** are optimized for scavenging, enhancing both power delivery and exhaust gas recirculation (EGR) functionality. The **spark plug bores** are precision-machined to accommodate the **NGK or Bosch high-energy spark plugs**, ensuring reliable ignition even under high-load conditions. Additionally, the cylinder head incorporates **integrated oil galleries and cooling passages**, which are critical for dissipating heat and preventing thermal warping a common issue in high-performance engines. The **valve springs and retainers** are designed to handle the aggressive valvetrain dynamics of the **164 TY**, which may include modifications such as **forged internals, upgraded camshafts, or high-flow headers**, making this part a **must-replace component** for engines undergoing performance upgrades.

For **2007 S-Class owners** seeking to restore factory performance, replace a worn or damaged head, or prepare their vehicle for a **turbocharged or supercharged conversion**, this **OEM-quality cylinder head** ensures a seamless fit with the **block, gasket (210987), and rocker arm cover (210986)**. The **210989** is also compatible with **aftermarket performance kits**, including **high-flow intake and exhaust manifolds, upgraded valve springs, and custom camshafts**, making it a versatile choice for both **restoration and modification projects**. When installed correctly with the proper **gasket, torque specifications (10 Nm for the head bolts in stages), and valve train adjustments**, this cylinder head will restore or enhance the engine s **power output, reliability, and longevity**, ensuring that the **S-Class s legendary driving dynamics** remain intact. Whether for a **daily driver, a high-performance build, or a classic restoration**, the **Mercedes-Benz 210989 right cylinder head** is an essential component for maintaining the **precision and power** that define the **W221 S-Class s engineering legacy**.

### **Pros and Cons of Buying a Mercedes-Benz 210989 Right Engine Cylinder Head (2007 S-Class, 164 Ty)**

1. **Compatibility and Fitment** This part is a direct replacement for the right cylinder head in a 2007 Mercedes-Benz S-Class (W221) with the **M272 E63 V8 engine (164 HP "Ty" variant)**. It ensures proper alignment with the engine bay, intake manifold, and exhaust system, reducing the risk of leaks or misalignment issues.

2. **OEM Quality** Mercedes-Benz parts are engineered to meet the manufacturer s exact specifications, ensuring reliability, durability, and performance comparable to a new head. This minimizes long-term wear and tear compared to aftermarket alternatives.

3. **Warranty Coverage** Purchasing from an authorized dealer or a reputable supplier often includes a warranty (typically 12 24 months), providing peace of mind against manufacturing defects or premature failure.

4. **Performance and Efficiency** A properly installed cylinder head ensures optimal combustion, which can improve fuel efficiency, power output, and engine longevity. If the original head was damaged (e.g., from overheating or cracking), replacing it restores the engine s intended performance.

5. **Resale Value** Keeping the vehicle in top condition with genuine parts helps maintain its resale value, especially for high-end luxury models like the S-Class.

6. **Reduced Risk of Future Issues** If the original head had internal damage (e.g., warped deck, cracked combustion chambers, or worn valve guides), replacing it prevents secondary problems like oil leaks, misfires, or catastrophic failure.

7. **Professional Installation Support** Many suppliers offer installation services or guidance, ensuring the head is correctly gasketed, torqued, and aligned, which is critical for preventing leaks or compression loss.

---

1. **High Cost** OEM cylinder heads are significantly more expensive than aftermarket alternatives. For a 2007 S-Class, prices can range from **$1,500 to $3,000 **, depending on the supplier and whether additional components (e.g., gaskets, bolts) are included.

2. **Labor Intensity** Replacing a cylinder head requires disassembling the engine, removing the intake/exhaust manifolds, and performing precise adjustments. This is a **multi-hour job** that typically requires a mechanic with experience in Mercedes-Benz engines, adding to labor costs (often **$1,500 $3,500 ** depending on the shop).

3. **Potential for Hidden Damage** If the engine was previously damaged (e.g., from overheating, detonation, or poor maintenance), the cylinder head may have internal stress or cracks that aren t immediately visible. A thorough inspection (ultrasonic testing, magnaflux, or pressure testing) may be needed before installation.

4. **Limited Availability** While this part is common for the W221 S-Class, sourcing it from a trusted supplier (especially for rare variants like the "Ty" engine) can be challenging. Buying from unscrupulous sellers may result in counterfeit or mismatched parts.

- **Gaskets** (head gasket, intake/exhaust manifold gaskets)

- **Bolts** (new cylinder head bolts are required per Mercedes service bulletins)

- **Valves/Seats** (if worn or damaged)

- **Oil pump kit** (if the engine was overheated)

- **Coolant system flush** (to remove old coolant and prevent corrosion)

6. **Risk of Overpaying** Some sellers inflate prices for "rare" or "high-demand" parts. Researching market prices (e.g., through **Mercury Marine, eBay, or specialist forums**) helps avoid overpricing.

7. **Time Off the Road** A cylinder head replacement is a major service job that can take **2 5 days** depending on the shop s workload. This downtime may be inconvenient for daily drivers.

---

- The engine is experiencing **misfires, compression loss, or overheating**.

- You prioritize **long-term reliability and performance** over cost savings.

- You have access to **professional installation** and are prepared for the associated labor costs.

- The part is sourced from a **trusted supplier** to avoid counterfeit or damaged goods.

However, if the engine has **significant internal damage** (e.g., warped block, seized valves, or a blown head gasket), replacing just the head may not be sufficient additional repairs (e.g., deck machining, valve job, or even a full engine rebuild) may be necessary.

---

1. **Verify the Need** Confirm the issue is **exclusively the cylinder head** (not the block, pistons, or valves) via a **compression test, leak-down test, or ultrasonic inspection**. If the engine has other problems, address them simultaneously.

2. **Source from a Reputable Supplier**

- **Authorized Mercedes-Benz parts dealers** (e.g., MBUSA, local dealerships).

- **Specialist online retailers** (e.g., **Mercury Marine, eBay verified sellers, or forums like S-Class.org**).

- Avoid **eBay "private sellers"** unless they have strong feedback and clear documentation.

3. **Budget for Full Repair**

- **Part Cost:** $1,500 $3,000 (OEM head gaskets/bolts).

- **Labor Cost:** $1,500 $3,500 (depending on shop rates).

- **Additional Costs:** Coolant flush, valve job, or engine diagnostics if needed.

- **Total Estimated Cost:** **$3,000 $6,000 **.

4. **Consider Aftermarket Alternatives (If Budget is Tight)**

- **High-quality aftermarket heads** (e.g., **Fel-Pro, Felgus, or Bosch**) can be **30 50% cheaper** but may lack long-term warranty support.

- **Remanufactured heads** (e.g., from **Mercedes-Benz remanufacturing centers**) offer a balance of cost and reliability.

5. **Choose a Skilled Mechanic**

- Look for shops with **Mercedes-Benz certification** and experience with **M272 engines**.

- Request a **detailed quote** and ask for references.

6. **Post-Installation Checks**

- **Break-in period:** Follow the mechanic s advice on oil changes and driving habits.

- **Monitor for leaks, misfires, or overheating** in the first 1,000 miles.

- **Schedule a follow-up inspection** after 500 1,000 miles to ensure proper sealing.
