Review TIMKEN Acura Crankshaft Seal Front fits LEGEND 1986–1995

The **Timken 67668SGNB** is a premium, high-performance front crankshaft seal designed specifically for the **1986 1995 Acura Legend (including the 1987 1989 models)**, ensuring a reliable, long-lasting seal for the engine s front crankshaft area. Engineered with Timken s reputation for durability and precision, this seal is crafted from high-quality **nitrile rubber**, reinforced with a **steel spring retainer** and a **galvanized steel shield** to prevent oil leaks, contamination, and premature wear critical factors for maintaining optimal engine performance and longevity. The **SGNB** designation indicates a **snap-in, grease-nibbed** design, which simplifies installation while providing a secure, vibration-resistant fit that resists loosening over time. This seal is meticulously manufactured to meet or exceed OEM specifications, ensuring a perfect match with the **Acura Legend s front cover**, whether equipped with a **2.5L or 3.0L inline-6 engine** (common in the 1987 1989 models). Its **lip-style construction** creates a tight seal against the crankshaft, effectively blocking oil from leaking into the timing chain or belt area while preventing dirt and debris from entering the engine. Ideal for both **replacement and upgrade applications**, this seal is built to withstand the demands of high-mileage engines, extended service intervals, and varying operating conditions, making it a trusted choice for mechanics and DIY enthusiasts alike. Proper installation requires careful alignment with the engine s front cover and the use of the included **grease nibs** to ensure a proper seal, while Timken s engineering ensures it remains resilient against heat, pressure, and mechanical stress keeping your Acura Legend s engine running smoothly for years to come.

### Pros and Cons of buying a Timken 67668SGNB Crankshaft Seal for a 1986 1995 Acura Legend (1987 1989 Front)

1. **Direct Fitment** The Timken 67668SGNB is specifically designed for the front crankshaft seal on 1987 1989 Acura Legend models (and extends to 1986 1995 in some cases). This ensures compatibility with your engine s dimensions and mounting points, reducing the risk of installation issues.

2. **High-Quality Materials** Timken is a well-known manufacturer of premium automotive seals, bearings, and related components. Their products are engineered for durability, resistance to oil and heat, and long-term performance, which helps prevent premature failure.

3. **Reliability** Timken seals are widely trusted in the automotive aftermarket for their consistent quality. Many mechanics and DIYers prefer Timken over generic or lower-grade alternatives due to their reputation for lasting longer without leaks.

4. **Ease of Installation** The seal is designed to fit standard tools and procedures for crankshaft seal replacement. While some models may require special tools (like a seal installer or puller), the Timken part is straightforward compared to aftermarket knockoffs that may not align perfectly.

5. **Warranty Coverage** Timken often provides warranties on their seals, offering some peace of mind in case of defects or early failure. This can be particularly valuable if you re unsure about the quality of cheaper alternatives.

6. **Prevents Costly Damage** A failing crankshaft seal can lead to oil leaks, which may contaminate the timing belt or chain, damage the water pump, or even cause engine damage if oil enters the cylinder head. Replacing it proactively avoids these secondary issues.

7. **Aftermarket Availability** Timken parts are widely available through auto parts stores (O Reilly, AutoZone, RockAuto), online retailers (Amazon, RockAuto, eBay), and specialty suppliers. This makes it easier to source than rare or discontinued OEM parts.

1. **Higher Cost** Timken seals are premium-priced compared to generic or no-name alternatives. While the price reflects quality, it may be a significant investment if you re on a tight budget, especially if you need additional parts (like a new timing belt or water pump) during the same service.

2. **Potential Overkill for Some Applications** If your Legend s seal failure is isolated to minor wear (e.g., a slow leak rather than a complete failure), a Timken seal might be more durable than necessary. In such cases, a mid-range aftermarket seal could suffice without the extra cost.

3. **Installation Complexity** Replacing a crankshaft seal often requires removing the timing belt/chain, water pump, and possibly the alternator or other components. While the seal itself is simple, the labor-intensive nature of the job means you ll need mechanical skill or a mechanic s help which adds to the total cost.

4. **Risk of Contamination During Installation** If not handled carefully, old oil or debris can be pushed into the engine during removal or installation. This can lead to further issues if the oil isn t properly cleaned out afterward.

5. **Mixed Reviews on Longevity in Some Cases** While Timken is generally reliable, some users report that the seal may not last indefinitely, especially in high-mileage or heavily modified engines. Factors like oil quality, maintenance history, and driving conditions can affect performance.

6. **Possible Counterfeit Concerns** If purchasing from third-party sellers (e.g., eBay, Amazon), there s a risk of receiving a counterfeit or low-quality Timken knockoff. Always verify the seller s reputation and check for authenticity markings on the seal.

7. **Alternative Options May Be Cheaper** Other reputable brands (e.g., Gates, Fel-Pro, or ATE) offer crankshaft seals at lower prices with comparable quality. While Timken is excellent, these alternatives might be sufficient for your needs without the premium price.

The Timken 67668SGNB crankshaft seal is an excellent choice for your 1987 1989 Acura Legend (and compatible models) due to its direct fitment, durability, and reliability. It s a wise investment if you prioritize long-term performance and want to avoid the hassle of frequent replacements or secondary damage from a failing seal. However, the higher cost and labor-intensive installation should be weighed against your budget and mechanical comfort level.

If you re confident in your DIY skills and want the best possible seal, Timken is a strong recommendation. If you re working with a tight budget or prefer to test a mid-range option first, consider alternatives like Gates or Fel-Pro seals, which may offer similar performance at a lower cost.
