Review ACURA Crankshaft Front And Rear Main Oil Seal Genuine Oem New fits RSX 2005–2006

The **Acura RSX Type S (2005 2006) Crankshaft Front and Rear Oil Seals (OEM Part Numbers 0506RSFRMS)** are precision-engineered aftermarket components designed to restore critical sealing performance in the high-performance Type S engine bay. These seals are meticulously crafted to match the exact specifications of the original equipment manufacturer (OEM) parts, ensuring a perfect fit within the 2.0L Honda K20Z3 engine s crankshaft housing and front cover assembly. The front oil seal, positioned between the crankshaft and the timing cover, prevents oil leakage while maintaining smooth crankshaft rotation, a critical function in maintaining engine longevity and performance especially under the high RPM demands of the RSX Type S s 200-horsepower turbocharged or naturally aspirated engine configurations. Similarly, the rear oil seal, located at the opposite end of the crankshaft near the transmission, seals the interface between the crankshaft and the bellhousing, preventing oil from seeping into the transmission or onto the drivetrain components, which can lead to costly contamination and wear.

Constructed from high-quality elastomeric materials reinforced with synthetic fibers, these seals are engineered to withstand the thermal and mechanical stresses of high-performance driving, including aggressive acceleration, spirited cornering, and prolonged high-RPM operation. The front seal features a robust lip design optimized for durability, while the rear seal incorporates a precision-molded shape to accommodate the unique contours of the RSX s crankshaft splines, ensuring a consistent and leak-free seal even under dynamic conditions. Both seals are compatible with the RSX Type S s 170-horsepower NA (naturally aspirated) and 200-horsepower turbocharged variants, making them a versatile upgrade for enthusiasts seeking to eliminate persistent oil leaks or replace worn OEM components. Installation is simplified with the use of specialized tools like seal drivers and removal tools, allowing mechanics to replace these seals efficiently without risking damage to the crankshaft or engine bay components. Whether addressing a minor oil leak or performing a routine maintenance overhaul, these **Acura RSX Type S Crankshaft Oil Seals** provide a reliable, long-lasting solution that upholds the integrity of your engine s critical sealing surfaces.

### Pros and Cons of Buying an Acura RSX (Type S) Crankshaft Front and Rear Oil Seals (05-06 Models)

#### **Pros:**

1. **Improved Reliability** Worn or leaking oil seals can cause oil leaks, reduced engine efficiency, and potential damage to internal components. Replacing them ensures better long-term engine health and prevents costly repairs.

2. **Prevents Oil Contamination** A failing oil seal can allow oil to enter the transmission or differential, leading to sludge buildup and premature wear. Replacing them eliminates this risk.

3. **Better Performance** A properly sealed crankshaft ensures optimal lubrication, reducing friction and improving engine responsiveness, especially in high-performance applications like the RSX Type S.

4. **Prevents Valve Cover Leaks** If the rear main seal is failing, it can cause oil to leak onto the timing chain or valve cover gasket, leading to a more extensive repair if ignored.

5. **Cost-Effective Maintenance** Replacing seals early is cheaper than dealing with a seized engine, transmission failure, or timing chain issues.

6. **Compatibility with Modifications** If you ve modified your RSX Type S (e.g., forced induction, high RPM tuning), fresh seals help maintain proper lubrication under increased stress.

7. **Easier Future Repairs** A clean engine bay with properly installed seals makes future maintenance (e.g., timing chain replacement, valve cover gasket work) simpler and less messy.

---

#### **Cons:**

1. **Labor Intensity** Replacing crankshaft seals, especially the rear main seal, requires significant disassembly (removing the engine from the subframe or performing a "half-engine" removal). This can be time-consuming and labor-heavy.

2. **Specialized Tools & Skills** Proper installation often requires precision tools (e.g., seal drivers, torque wrenches, and experience with engine disassembly). Poor installation can lead to leaks or premature failure.

3. **Cost of Parts** High-quality aftermarket or OEM seals (especially for the rear main seal) can be expensive, and some owners opt for budget options that may not last as long.

4. **Potential for Additional Damage** If the seals have been leaking for a while, oil may have contaminated other components (e.g., timing chain, bearings). A thorough inspection may reveal further issues requiring repair.

5. **Time Commitment** For DIYers, this job can take **10-20 hours**, depending on experience and engine setup. Some may prefer professional help, adding to costs.

6. **Risk of Improper Installation** If not installed correctly, seals can leak or fail prematurely, negating the benefits of replacement.

7. **Compatibility Issues with Aftermarket Parts** Some aftermarket seals may not fit perfectly with modified engines (e.g., turbocharged or supercharged RSX Type S builds), requiring custom solutions.

### **Conclusion:**

Replacing the crankshaft front and rear oil seals on a **2005-2006 Acura RSX Type S** is a **highly recommended maintenance task** for long-term engine reliability, especially if the car is heavily driven, modified, or shows signs of leaks. The **pros far outweigh the cons** in terms of preventing catastrophic failure and maintaining performance. However, the **labor-intensive nature, cost, and potential for additional repairs** mean it s not a trivial job it requires careful planning, the right tools, and either mechanical skill or access to a trusted mechanic.

If your RSX is showing **oil leaks (front or rear), blue smoke from the exhaust, or oil contamination in the transmission/differential**, the seals should be replaced **immediately** to avoid severe engine damage. For a **well-maintained, stock RSX**, this job is a **proactive investment** rather than an emergency fix.

---

### **Recommendation:** 1. **If You re Experienced & Have the Time:**

- **DIY the job** using high-quality seals (e.g., **Fel-Pro, Sealed Power, or OEM replacements**).

- Follow a **step-by-step guide** (e.g., from *Haynes Manual* or *Acura RSX forums*) and take your time.

- Consider **removing the engine from the subframe** for easier access to the rear main seal.

- **Inspect other components** (timing chain, bearings, gaskets) while the engine is out this is a great opportunity to address other wear items.

2. **If You re Not Comfortable with Engine Work:**

- **Take it to a reputable mechanic** specializing in Acura/Honda engines. Ensure they have experience with **R18A1 engines** (the RSX s engine).

- **Get a second opinion** if the mechanic suggests additional work (e.g., timing chain replacement) due to wear.

3. **Budget Considerations:**

- **Parts Cost:** $100 $300 (depending on quality and whether you need a new timing chain/guide).

- **Labor Cost:** $800 $1,500 (if done professionally).

- **DIY Savings:** You ll save significantly on labor, but factor in **tool costs** (e.g., engine hoist, seal drivers, torque wrench).

4. **Preventative Maintenance Tip:**

- If you re unsure about the condition of your seals, **check for leaks** (oil spots under the car, around the crankshaft pulley, or on the timing chain cover).

- **Change oil regularly** (every 5,000 7,500 miles) to reduce wear on seals and other components.

**Final Verdict:** **Do it now if you suspect seal failure.** The long-term benefits of preventing engine damage and maintaining performance make it a **smart investment** for your RSX Type S.

Details:

The parts must be in pristine condition, uninstalled, and free from damage caused by incorrect installation, missing parts, hardware, or instructions. OEM parts are made to the same exacting specifications as that were originally installed in vehicle, which can provide greater reliability, durability, and longevity.
