The sump gasket seals the oil sump plate and oil strainer assembly to prevent engine oil leakage. It helps maintain proper oil containment and supports reliable lubrication system operation.
Sold each, 2 gaskets required per engine

Fits:
Porsche 911 1965 - 1989
Porsche 930 Turbo 1975 - 1989
Porsche 964 1989 - 1994

Porsche 914 1970 - 1976

Diagram ref no 42.

Installed at the lower section of the engine crankcase, the gasket seals the oil sump plate and helps prevent oil leakage from the engine lubrication system. Proper sealing is critical for maintaining correct oil retention, preventing contamination, and ensuring reliable engine lubrication. The gasket is commonly replaced during oil changes, sump plate servicing, or engine rebuild work.

Function
•  Seals oil sump plate and oil strainer assembly
• Prevents engine oil leakage
• Maintains proper oil retention within crankcase
•  Supports reliable engine lubrication system operation
•  Resists oil exposure and engine heat

Over time, sump gaskets can harden, compress, or deteriorate due to constant exposure to engine oil and heat. A worn gasket may cause oil leaks, reduced sealing performance, and contamination around the sump area. Replacing the gasket during servicing helps maintain proper oil sealing and prevents oil loss from the lubrication system.

When to replace
• Oil leakage around sump plate area
• During oil strainer or sump plate servicing
• Hardened, cracked, or compressed gasket material
• During engine rebuild or maintenance work
• Preventative replacement during oil service

The sump gasket seals the joint between the engine sump plate and crankcase, preventing engine oil leaks while maintaining proper oil circulation and pressure. It is used during servicing of the oil strainer and sump plate assembly, ensuring a reliable seal after removal or maintenance.

Functions & Technical Role
• Oil sealing: Prevents leaks around the sump plate and oil strainer
• Pressure retention: Helps maintain correct lubrication system integrity
• Service component: Replaced whenever the sump plate is removed
• Engine protection: Supports proper oil containment and circulation
• OEM specification: Manufactured to Porsche factory dimensions and material standards

Fitment / Position on car
• Fitting position: Engine lubrication system
•  Location: Between the oil sump plate / oil strainer cover and engine case
•  System: Engine oil circulation and filtration

Over time, sump gaskets can become:
•  Compressed or brittle
• Damaged during removal
• Unable to seal properly after reuse

A failing gasket can lead to:
•  Engine oil leaks
• Reduced oil retention
•  Contamination around the sump plate area

Replacing with a genuine Porsche OE gasket ensures proper sealing and helps protect the engine lubrication system.
