Restore reliable engine oil sealing and eliminate troublesome oil pan leaks with the Cometic D-Series Oil Pan Gasket (C4660). Designed for select Honda D15, D16, and early Honda engine applications, this replacement oil pan gasket provides a dependable seal between the engine block and oil pan, helping prevent oil leaks and maintain proper engine lubrication.

Cometic is a trusted manufacturer of high-performance automotive gaskets, producing sealing solutions for everything from factory engine rebuilds to demanding motorsports applications. The C4660 oil pan gasket is engineered to fit compatible Honda and Acura engines while providing the durability and sealing performance required for everyday driving and performance use.

The oil pan gasket plays an essential role in keeping engine oil contained within the crankcase. Over time, factory gaskets can deteriorate, become compressed, or lose their ability to maintain a proper seal. This can lead to oil seepage, visible leaks, and oil accumulation around the bottom of the engine.

Whether you're repairing a leaking oil pan, rebuilding a Honda D-Series engine, installing a replacement oil pan, or completing a performance engine build, the Cometic C4660 Oil Pan Gasket offers a quality replacement solution designed to maintain a secure seal under normal and demanding operating conditions.

• Engine Rebuilds: A new oil pan gasket is an essential component during bottom-end engine assembly.

• Damaged Sealing Surfaces: A compromised gasket may no longer seal properly after repeated oil pan removal.

• Oil Pan Replacement: Installing a replacement or compatible performance oil pan requires a properly fitted gasket.

• Preventative Maintenance: Replacing a deteriorated gasket helps prevent future oil leaks and unnecessary oil loss.

• Performance Engine Builds: Fresh sealing components are important when assembling modified or high-output D-Series engines.

Installation Notes

1. Verify Engine Compatibility: Confirm that Cometic part number C4660 is correct for your Honda or Acura engine and oil pan configuration.

2. Prepare the Vehicle: Park on a level surface, allow the engine to cool, and securely support the vehicle using approved lifting points and properly rated jack stands.

3. Drain the Engine Oil: Remove the oil drain plug and completely drain the engine oil into an appropriate collection container.

4. Remove Obstructing Components: Depending on the vehicle, additional brackets, exhaust components, or protective covers may need to be removed to access the oil pan.

5. Remove the Oil Pan: Carefully loosen and remove the oil pan mounting hardware. Separate the oil pan from the engine block without damaging the sealing surfaces.

6. Remove the Old Gasket: Completely remove the existing oil pan gasket and any residual sealing material from the mating surfaces.

7. Inspect the Oil Pan: Check the oil pan flange for distortion, cracks, corrosion, or damage around the mounting holes. Repair or replace damaged components before installation.

8. Clean the Sealing Surfaces: Thoroughly clean the oil pan and engine block mating surfaces. Ensure both surfaces are free from oil, dirt, debris, and old gasket material.

9. Position the New Gasket: Install the Cometic C4660 gasket according to the manufacturer's instructions, ensuring that it is properly aligned with the oil pan mounting holes and sealing surfaces.

10. Apply Sealant Where Required: Follow the Honda service manual and Cometic installation instructions for any specified sealant application points. Avoid applying excessive sealant.

11. Reinstall the Oil Pan: Carefully position the oil pan against the engine block without shifting or damaging the gasket.

12. Tighten the Mounting Hardware: Install and tighten the oil pan fasteners in the recommended sequence using the factory torque specifications. Avoid overtightening, which can distort the oil pan flange or damage the gasket.

13. Refill the Engine Oil: Reinstall the drain plug and refill the engine with the correct type and quantity of engine oil.

14. Check for Leaks: Start the engine, allow it to reach operating temperature, and inspect the oil pan sealing area for leaks.

15. Perform a Final Inspection: After a short test drive, recheck the engine oil level and inspect the oil pan for any signs of seepage.

Installation Recommendation: Proper surface preparation and correct fastener torque are essential for preventing oil pan leaks. Always follow the applicable Honda service manual and Cometic installation instructions.
