Jaguar 4.2L V8 Oil Pan Gasket Transmission Engine Displacement C2S43270

Product Specification

 Jaguar 4.2L V8 Engine Displacement  Oil Pan Gasket C2S43270  Car Engine System

1. Vehicle Compatibility Table

This gasket is primarily compatible with Jaguar models equipped with specific V8 engines, for example:

 Please note: This list is based on common compatibility. The most accurate way to confirm is to check your vehicle's VIN number.

2. Technical Features
    This oil pan gasket incorporates several advanced technologies to ensure reliability:

• • Precision Molding: Manufactured using Computer-Aided Design (CAD) and precision molds to ensure a perfect fit with the Jaguar engine block and oil pan surfaces, providing even pressure distribution.

  • Material Engineering: Typically made from advanced materials like Fluoroelastomer (FKM/Viton®) or Hydrogenated Nitrile Butadiene Rubber (HNBR). These materials offer long-term resistance to engine oil additives (including synthetic oils), high-temperature oxidation, and stress fatigue from thermal cycling.

  • Structural Design: Some designs include an embedded metal core (e.g., steel), providing superior support and resistance to extrusion and deformation, preventing bolt torque loss.

  • Surface Treatment: Many gaskets are pre-coated with an anaerobic sealant. This coating cures in the absence of air and between metal surfaces (after the bolts are tightened), forming a second, reliable sealing barrier.

3. Working Principle
     The oil pan gasket works by filling and sealing the microscopic imperfections between the oil pan and the engine block mating surfaces. It creates a seal by maintaining constant compressive force (from bolt torque and the gasket's own elasticity), preventing engine oil from leaking out of the pan. The pre-applied sealant flows into and fills these micro-imperfections, achieving a comprehensive seal.

4. Primary Purpose

• • Core Function: To prevent oil leaks, ensuring the engine maintains proper oil level and pressure for critical lubrication.

  • Contaminant Protection: Seals out external contaminants (like dirt and moisture) from entering the engine crankcase, protecting the oil's cleanliness.

  • Engine Performance Maintenance: A reliable seal is fundamental to maintaining engine efficiency and longevity (e.g., preventing wear due to oil loss).

  • Maintenance Application: This part is replaced when the old gasket has aged, compressed, or failed during oil changes, engine lower-end repairs, or when troubleshooting oil leaks.

 5. Installation Notes

Proper procedure is crucial when replacing this gasket:

1. Surface Cleaning: It is essential to thoroughly clean both the engine block and oil pan mating surfaces, removing all traces of old sealant and oil to ensure the new gasket seals on a flat, clean surface.

2. Torque Specification: Precisely follow the manufacturer's specified bolt tightening sequence and torque values to avoid distorting the gasket or pan, which can cause leaks.

3. Leak Check: After installation, refill with engine oil, start the engine, and check carefully for any signs of leakage.
