Review RAM 3.0l Diesel Passenger Right Rh Cylinder Head Oem fits 1500 2014–2018

The **RAM 3000 3.0L Diesel Cylinder Head (Part # 90352084G, 2014 2018)** is a precision-engineered component designed specifically for the high-performance and durability demands of Chrysler s 3.0L Cummins diesel engine, found in the iconic RAM 1500 and 3000 models from 2014 through 2018. Crafted from high-grade cast iron, this cylinder head is engineered to withstand the extreme pressures and thermal stresses generated by the turbocharged, direct-injection diesel system, ensuring reliable operation under heavy loads, towing, and off-road conditions. The head features a **four-valve-per-cylinder design**, with intake and exhaust valves strategically positioned to optimize airflow and combustion efficiency, contributing to the engine s legendary torque and fuel economy. The **integrated camshaft lobes** and **hydraulic lifters** work in tandem to minimize friction and wear, while the **precision-machined combustion chambers** promote cleaner, more complete fuel combustion, reducing emissions and extending engine life. This part is fully compatible with the **Eaton turbocharger system**, **common rail fuel injection**, and **selective catalytic reduction (SCR) emissions control**, making it a critical component for maintaining the Cummins reputation for rugged reliability. Whether restoring a classic diesel truck or upgrading an existing engine, this cylinder head delivers the structural integrity and performance consistency required to keep the RAM s powerful diesel heart running at peak efficiency for thousands of miles. Proper installation, including the use of high-quality gaskets and torque specifications, is essential to prevent leaks and ensure optimal thermal management, preserving the engine s longevity and performance.

### **Pros and Cons of Buying a RAM 90352084G (2014 2018 1500 3.0L Diesel) Passenger Right-Hand Drive (RHD) Cylinder Head**

#### **Pros**

1. **Reliability of the 3.0L Cummins Diesel Engine**

- The Cummins ISB 3.0L diesel is known for its durability, especially in heavy-duty applications. With proper maintenance, these engines often last well beyond 300,000 miles.

- The turbocharged direct-injection system provides strong torque, making it suitable for towing and hauling.

2. **Strong Aftermarket Support**

- The Cummins 3.0L has a large aftermarket community, meaning parts (e.g., injectors, turbochargers, fuel pumps) and modifications (e.g., tuning, exhaust upgrades) are widely available.

- Common issues (e.g., fuel pump failures, turbo wear) have well-documented fixes and upgrades.

3. **Potential for High Resale Value**

- Diesel trucks, especially well-maintained Cummins models, retain value better than gasoline counterparts in certain markets (e.g., commercial, off-road, or high-mileage buyers).

- If the cylinder head is in good condition, it could appeal to buyers looking for a reliable work truck.

4. **Fuel Efficiency**

- Diesel engines typically offer better fuel economy than gasoline engines, especially on highways, which can be cost-effective for long-distance driving.

5. **Potential for Modifications**

- The Cummins platform allows for upgrades like larger turbos, high-flow fuel systems, and performance exhausts, which can enhance power and longevity.

6. **Availability of Parts**

- Since the 3.0L Cummins was produced for several years, finding replacement parts (even for the cylinder head) is relatively straightforward compared to rare or discontinued engines.

---

#### **Cons**

1. **Common Cylinder Head and Valve Train Issues**

- The **90352084G cylinder head** (and similar models) has a history of **valve train wear**, particularly with the **hydraulic lash adjusters (HLA)** failing prematurely, leading to excessive noise and potential damage if ignored.

- **Exhaust valve leaks** and **warped valve seats** are frequent problems, often requiring a full valve job or head replacement.

- **Head gasket failures** can occur if the engine overheats or if the head bolts are not torqued correctly during assembly.

2. **Fuel System Reliability Concerns**

- The **fuel injectors** (especially early models) are prone to **leaking or failing**, leading to misfires and poor performance.

- The **fuel pump** (common rail or mechanical) may fail around **150,000 200,000 miles**, requiring a costly replacement ( $1,500 $2,500).

- **Common Rail pressure issues** can cause rough idling or stalling.

3. **Turbocharger Wear**

- The **turbocharger** in the 3.0L Cummins is known to wear out around **150,000 200,000 miles**, leading to **boost leaks, lag, and reduced power**.

- A new turbo can cost **$1,000 $2,000**, and labor adds significantly to the expense.

4. **High Maintenance Costs**

- While the engine itself is durable, the **fuel system, turbo, and valve train** require frequent attention, leading to higher long-term costs than a gasoline engine.

- **Oil consumption** can be an issue in some Cummins engines, requiring more frequent top-offs.

5. **Emissions and Modernization Issues**

- Later models (2017 ) may have **DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) system** complications, which can be expensive to repair if clogged or failing.

- Some states have **restrictions on diesel trucks**, making resale or registration difficult in certain areas.

6. **Potential for Hidden Problems**

- Without a **full service history**, it s difficult to know if the cylinder head has been properly serviced (e.g., valve adjustment, seat machining, or gasket replacement).

- **Overheating** can cause **warped heads, cracked blocks, or seized pistons**, which are catastrophic and expensive to repair.

7. **Diesel Fuel Availability and Cost**

- Diesel fuel can be **less available** than gasoline in some rural areas and may have **higher taxes** in certain regions.

- Fuel prices can fluctuate more than gasoline, affecting long-term operating costs.

---

### **Ending Conclusion**

- You **prioritize durability and torque** over fuel economy.

- You **plan to perform regular maintenance** (fuel system, turbo, valve train).

- You **find a well-documented example** with a **clean service history**.

- You **budget for potential major repairs** (fuel pump, turbo, cylinder head work).

However, it is a **high-maintenance purchase** that requires **mechanical knowledge or access to a trusted mechanic**. The **cylinder head itself may need attention** (valve job, seat machining, or replacement), and if the engine has **high miles without proper care**, the costs can add up quickly.

---

### **Recommendation**

- **Get a pre-purchase inspection (PPI) from a Cummins specialist** to check for **valve train wear, head leaks, turbo condition, and fuel system health**.

- **Verify the service history** look for **fuel pump, turbo, and valve adjustments** done at recommended intervals.

- **Budget for a valve job or head replacement** if the current head shows signs of wear.

- **Consider a used but well-maintained example** (under 150,000 miles) rather than a high-mileage brute.

- **Avoid diesel** unless you re certain you can handle the upkeep.

- **Consider a gasoline RAM 1500** (e.g., 5.7L Hemi) if you want **simpler, lower-cost ownership**.

- **Look for a Cummins with a known good cylinder head** (e.g., one that has had a **valve job within the last 50,000 miles**).

- The **Cummins 3.0L is still a strong choice** if you **plan to maintain it aggressively**.

- **Negotiate a lower price** if the seller cannot provide proof of recent valve work or turbo replacement.

The **RAM 1500 3.0L Cummins with a 90352084G cylinder head can be a great truck for the right buyer** someone who **understands diesel mechanics and is willing to invest in maintenance**. However, **it is not a "set-and-forget" purchase**, and buyers should **expect potential repairs** rather than relying on long-term reliability without upkeep. If you re not prepared for the maintenance, a **gasoline RAM or a well-documented diesel with a fresh valve job** would be the safer choice.
