Review DORMAN/AUTOGRADE Rivet

The **Dorman/Autograde 799-105 Rivet** is a high-performance, precision-engineered fastening solution designed to deliver exceptional strength, durability, and reliability in demanding automotive and industrial applications. Crafted from **high-grade, cold-headed steel**, this rivet is forged to exacting tolerances, ensuring consistent performance under extreme stress, vibration, and temperature fluctuations making it an ideal choice for structural repairs, bodywork, and heavy-duty assemblies where traditional bolts or welds fall short. With a **1/4-inch diameter shank** and a **5/16-inch head diameter**, this rivet strikes an optimal balance between holding power and ease of installation, allowing for clean, flush mounting in sheet metal, aluminum, and steel substrates without the need for additional hardware or sealing. The **smooth, polished finish** minimizes friction during insertion, reducing the risk of galling or stripping, while the **sharp, tapered point** ensures effortless penetration through pre-punched or drilled holes, even in thicker materials. Engineered to withstand **high shear and tensile loads**, this rivet is particularly well-suited for applications such as **frame repairs, suspension components, exhaust systems, and custom fabrication projects** where a permanent, vibration-resistant joint is critical. Its **self-locking design** prevents loosening over time, eliminating the need for additional locking mechanisms like nuts or washers, while the **corrosion-resistant steel** provides long-term protection against rust and degradation in harsh environments. Whether used in professional shop settings or by serious DIY enthusiasts, the **Dorman/Autograde 799-105 Rivet** offers a dependable, cost-effective alternative to welding or riveting tools, delivering a professional-grade finish with minimal effort. Its compatibility with standard rivet guns and the absence of protruding heads make it a versatile solution for both new construction and restoration work, ensuring a clean, professional appearance while maintaining structural integrity.

### **Pros and Cons of buying a Dorman/Autograde 799-105 Rivet (Exhaust Manifold Gasket Kit)**

1. **Compatibility** The 799-105 is designed specifically for GM V8 engines (including the LS-series and older small-block and big-block configurations), ensuring a proper fit without modification.

2. **Durability** Made from high-quality materials, including riveted construction, this gasket kit is built to withstand high temperatures and engine stress, reducing the risk of leaks over time.

3. **Easy Installation** The pre-drilled and pre-riveted design simplifies installation compared to traditional gaskets, reducing labor time and potential errors.

4. **Reliability** Dorman and Autograde are well-regarded brands in the aftermarket, known for consistent quality and performance in exhaust manifold applications.

5. **Cost-Effective** While not the cheapest option, it strikes a balance between affordability and durability, avoiding the need for frequent replacements.

6. **Prevents Leaks** Properly installed, this gasket helps seal exhaust ports effectively, reducing exhaust gas leaks and maintaining engine efficiency.

7. **Widely Available** Easy to find at auto parts stores, online retailers, and through trusted mechanics, ensuring accessibility.

1. **Limited Engine Compatibility** Only suitable for GM V8 engines (not suitable for inline-6, V6, or non-GM applications), which may require additional research before purchase.

2. **Potential Overkill for Some Engines** If the original gasket was already functioning well, replacing it may not be strictly necessary unless there are signs of failure (e.g., leaks, cracks).

3. **Installation Skill Required** While easier than traditional gaskets, improper installation (e.g., uneven seating, incorrect torque) can still lead to leaks or damage.

4. **Price** More expensive than basic paper or fiber gaskets, though justified by its durability and design.

5. **Rivet Design Limitations** The riveted construction may not accommodate minor bolt hole misalignments as flexibly as a traditional gasket, potentially requiring precise alignment during installation.

6. **Not Universal** Some GM engines (e.g., certain LS variants or older big-blocks) may require specific part numbers or additional components (e.g., gasket sealant), adding complexity.

### **Conclusion**

The Dorman/Autograde 799-105 rivet exhaust manifold gasket kit is a **high-quality, reliable choice** for GM V8 engines where exhaust leaks, cracks, or general wear are present. Its riveted design ensures better sealing and longevity compared to standard gaskets, making it a practical upgrade for performance and durability. However, it is **not a universal fix** it is engine-specific, and improper installation can negate its benefits. If your engine is running well without issues, replacing the gasket may not be urgent, but if leaks or damage are confirmed, this kit is a solid, long-term solution.

---

### **Recommendation**

- You have a GM V8 engine (LS-series, small-block, or big-block) with visible exhaust manifold gasket failure (leaks, cracks, or carbon buildup).

- You prioritize durability and ease of installation over cost.

- You plan to perform the replacement yourself and are comfortable with basic engine work.

- Your engine is not a GM V8 (check for a compatible gasket kit for your specific application).

- The original gasket is still intact and functioning, and you want to avoid unnecessary replacement.

- You prefer a cheaper option (e.g., a fiber or paper gasket) for minor maintenance rather than a premium upgrade.

- Always clean the mating surfaces thoroughly before installation.

- Use a high-temperature gasket sealant (if recommended for your engine) to enhance sealing.

- Follow the manufacturer s torque specifications to avoid damage.

- If unsure about compatibility, consult a mechanic or refer to your engine s service manual.

For most GM V8 owners dealing with exhaust manifold gasket issues, the **799-105 is a recommended choice** due to its balance of quality and ease of use.
