Review DETROIT 671 12v71 Diesel Cylinder Head Rebuilt But Rusty From Storage
The **Detroit Diesel 5117435 671 12V-71 cylinder head** is a robust, high-performance component designed for the legendary **Detroit Series 60 (671) diesel engine**, a workhorse known for its durability and reliability in heavy-duty applications such as commercial trucks, buses, and industrial machinery. This particular cylinder head is part of the **12-cylinder (12V) configuration**, which powers the **71-series** engine variant, renowned for its robust displacement and torque output. Crafted from high-grade cast iron, the head is engineered to withstand extreme operating conditions, including high compression ratios, intense heat, and prolonged exposure to demanding environments. Its design incorporates precision-machined combustion chambers, optimized valve ports, and integrated cooling passages to ensure efficient heat dissipation and optimal combustion performance. Over time, exposure to moisture, salt, and environmental contaminants can lead to surface corrosion, which is why this unit may exhibit signs of rust common in stored or long-term unused components. Despite this, the core structural integrity remains intact, making it a viable candidate for restoration or replacement in engines requiring a like-new cylinder head. Whether sourced for a classic Detroit diesel restoration project or a modern rebuild, this part offers a blend of historical significance and functional reliability, ensuring that the engine it serves will continue to deliver the power and endurance expected from Detroit s legendary diesel architecture.
### Pros and Cons of Buying a Rusty Stored Detroit Diesel Cylinder Head (Serial Number 5117435, Model 671, 12V71)
#### **Pros:**1. **Potential for Restoration** If the cylinder head is structurally sound beneath the rust, it can be restored to like-new condition with proper cleaning, machining, and sealing. This makes it a cost-effective option for someone with mechanical skills or access to a machine shop.
2. **Compatibility with Existing Engines** The Detroit Diesel 12V71 is a well-documented engine, meaning parts, manuals, and aftermarket support are widely available. If you already have a compatible engine or plan to rebuild one, this head could be a good fit.
3. **Lower Upfront Cost** Compared to buying a new or reconditioned cylinder head, a rusty used part is significantly cheaper, making it attractive for budget-conscious buyers.
4. **Learning Opportunity** Working on a rusted head can provide hands-on experience in engine repair, including cleaning, machining, and sealing techniques.
5. **Potential for Resale Value** If restored properly, a well-maintained Detroit Diesel cylinder head retains good resale value, especially in industrial or marine applications.
#### **Cons:**1. **Extensive Cleaning and Machining Required** Rust can cause pitting, warping, or internal corrosion, which may require extensive cleaning (using chemical or mechanical methods) and machining to restore proper sealing surfaces. This adds labor and material costs.
2. **Risk of Hidden Damage** Rust often masks deeper issues such as cracked castings, warped decks, or corroded internal passages. Without professional inspection, you may end up with a head that needs replacement rather than repair.
3. **Time-Consuming Process** Restoring a rusted head is labor-intensive. If you lack experience, it could take significantly longer than expected, delaying engine rebuilds or equipment repairs.
4. **Sealing Challenges** Rust can interfere with gasket surfaces, requiring precision machining to ensure proper sealing. If not done correctly, leaks or poor compression can result.
5. **No Warranty or Guarantee** Since the head is used and stored, there is no warranty or return policy. If issues arise during restoration, you bear the full cost of repairs.
6. **Potential for Overpaying** If the head is in poor condition, you may end up paying more than it s worth after accounting for restoration costs. Always compare the price to the cost of a reconditioned or new head.
7. **Environmental and Safety Risks** Rust cleanup often involves harsh chemicals (like muriatic acid or rust converters) that require proper ventilation and protective gear. Improper handling can pose health risks.

### **Conclusion:**Buying a rusty stored Detroit Diesel cylinder head can be a worthwhile investment if you are prepared for the work involved. The key factors to consider are your mechanical skill level, available time, budget for restoration, and whether the head is structurally sound beneath the rust. If you are confident in your ability to restore it properly, the cost savings can be significant. However, if you lack experience or time, the risks of hidden damage and excessive labor may outweigh the benefits.
For most buyers, purchasing a **reconditioned or new cylinder head** from a reputable supplier is the safer and more reliable option, as it eliminates uncertainty and ensures proper function. If you proceed with the rusty head, conduct a thorough inspection (or have a professional do so) before committing to avoid costly mistakes.
### **Recommendation:**- **If you have mechanical experience, access to tools, and patience**, proceed with caution, budget for restoration costs, and consider consulting a machine shop for an inspection.
- **If you lack experience or time**, opt for a reconditioned head from a trusted dealer to avoid unnecessary headaches.
- **Always verify the head s condition** look for signs of warping, cracks, or excessive pitting before purchasing. A visual inspection (or ultrasonic testing for hidden defects) is essential.
- **Negotiate the price** based on the head s apparent condition, accounting for the work needed to restore it.
Ultimately, the decision depends on your priorities: saving money now versus ensuring reliability and ease of repair. For most practical applications, a reconditioned part is the best balance of cost and performance.
