Oil Cooler Installation Kit For Early Engine Case With 6mm x 8mm Studs.
(Kit Includes Two Oil Cooler Seal Rings, Part And Two Studs)
The OE Match Oil Cooler Installation Kit for Early Engine Case with 6mm x 8mm Studs is a premium-quality engine installation kit designed to provide all the essential components required to correctly mount and seal the engine oil cooler on compatible early Porsche engines fitted with 6mm x 8mm mounting studs. Manufactured to OE specifications for fit, sealing performance and durability, this comprehensive kit ensures a secure, leak-free installation while maintaining correct oil flow and cooling efficiency.

Fits:

• Porsche 356 1950-55
• Porsche 356A 1955-59
• Porsche 356B 1959-63 

The kit contains high-quality OE-style seals, gaskets and installation hardware where applicable, all manufactured from premium heat- and oil-resistant materials capable of withstanding the demanding operating conditions of the Porsche lubrication system. Designed as a direct OE-style replacement, it is ideal when replacing the oil cooler, rebuilding an engine or carrying out preventative maintenance on early engine cases.

What This Product Does:

• Provides the components required to install the engine oil cooler correctly.
• Creates secure, leak-free seals between the oil cooler and engine case.
• Maintains correct engine oil flow through the oil cooler.
• Supports efficient engine oil cooling.
• Helps prevent oil pressure loss caused by leaking seals.
• Restores factory oil cooler installation standards.
• Ensures compatibility with early engine cases using 6mm x 8mm studs.
• Forms an essential part of the engine lubrication system.

Symptoms Of Wear Or Failure:

• Engine oil leaking around the oil cooler.
• Oil residue on the engine case or cooling fins.
• Low engine oil level due to external leaks.
• Reduced oil pressure caused by sealing failure.
• Oil contamination around the oil cooler mounting area.
• Hardened, cracked or compressed seals.
• Difficulty achieving a leak-free oil cooler installation.
• Oil dripping beneath the vehicle.
• Increased engine operating temperatures if oil flow is affected.
• Premature wear of lubrication system components.

Why Replacement Matters:

• Oil cooler seals and installation components are continually exposed to hot engine oil, pressure fluctuations and repeated thermal cycling. Over time, seals naturally harden, compress or lose their elasticity, reducing their ability to maintain an effective seal between the oil cooler and engine case.
• A leaking oil cooler installation can result in oil loss, reduced lubrication performance and contamination of the engine bay. If left unresolved, oil pressure may be compromised, increasing the risk of accelerated engine wear or serious internal damage. During oil cooler replacement or engine rebuilding, installing new seals and hardware is essential for reliable, long-term performance.
• Replacing the original installation components with the OE Match Oil Cooler Installation Kit ensures the oil cooler is mounted securely and sealed correctly. Manufactured to OE standards using premium-quality heat- and oil-resistant materials, this kit provides factory-style fitment, dependable sealing performance and long-lasting durability, helping maintain efficient engine cooling, reliable lubrication and the performance expected from your Porsche.
