Replacement RS31290007 Valve Cover Gasket Without Spark Plug Tube Seals

The Replacement RS31290007 is an aftermarket replacement valve cover gasket designed to restore a proper oil-tight seal on Subaru's horizontally opposed 2.5L SOHC (EJ25) four-cylinder engine. This gasket seals the mating surface between the valve cover and the cylinder head, preventing oil leaks that commonly develop as the original rubber deteriorates with age and repeated heat cycles.

This part is sold individually and does not include spark plug tube seals. If spark plug tube seals are also needed, they should be sourced separately (Subaru OEM reference: 10966AA030).

Key Features:

• Direct OEM-replacement fitment for Subaru EJ25 2.5L SOHC non-turbo engines
• Restores a leak-free seal between the valve cover and cylinder head
• Designed to match original equipment specifications and dimensions
• Does not include spark plug tube seals — gasket only
• Replaces OEM reference part number 13294AA070

Valve cover gaskets on Subaru flat-four engines are a well-known wear item. Oil seeping from the valve cover area onto hot exhaust components is a common symptom of a failed gasket. This replacement gasket provides a reliable, cost-effective solution to stop oil leaks and protect engine components from oil contamination.
