Diagram Ref No 27

Mounted in the camshaft housing area, sealing joints around the camshaft assembly to prevent oil leakage.

What this product does:
•  Creates a tight, reliable seal between the camshaft housing and adjoining engine components
•  Prevents engine oil leaks while ensuring smooth lubrication of the camshaft and valvetrain
•  Supports proper oil circulation and pressure, helping to protect moving parts from wear.

Over time, gaskets can harden, shrink, or crack due to heat and oil exposure.
A failing camshaft gasket may lead to:
• Oil leaks, causing messy engine bays or burning oil smells
• Reduced lubrication, risking wear to the camshaft and related components
• Potential damage to surrounding parts from leaking oil

Replacing with a genuine Porsche 90110519503 gasket ensures proper sealing, reliable lubrication, and preserves both the performance and longevity of your classic 911 engine.
