This OE Match exhaust valve guide is a precision-engineered replacement valve guide specifically designed for the Porsche 914 (1970–1976) air-cooled engines. This is a first-oversize exhaust guide intended to fit cylinder heads that may have experienced wear or require an oversize fit during an engine rebuild.
Sold individually, 4 required per engine.
Fits:
Porsche 914-1,7/1,8V
Porsche 914-1,8
Diagram ref no 15
This exhaust valve guide ensures that the exhaust valve stem remains centered and aligned as it moves, reducing lateral movement and minimizing wear on both the valve stem and seat. By guiding the valve smoothly and maintaining proper clearances, it helps preserve engine compression, reduces oil consumption, and contributes to efficient exhaust flow and combustion stability. Valve guides also aid in conducting heat away from the valve stem into the cylinder head, helping protect components from excessive thermal stress.
Valve guides are typically sold individually; a complete head rebuild will normally require four exhaust valve guides (one for each exhaust valve).
Function
• Valve Alignment: Keeps the exhaust valve traveling straight for proper valve seat engagement and sealing.
• Wear Control: Reduces lateral valve stem movement that would otherwise accelerate wear on the valve and seat.
• Heat Dissipation: Helps carry heat from the hot exhaust valve stem into the cylinder head.
• Rebuild Support: Oversize fit for cylinder heads that have been reamed or show wear.
Valve guides wear over time due to high heat, friction, and repeated motion. Worn guides can result in:
• Excessive oil entering the combustion chamber
• Poor compression, rough idle or power loss
• Increased valve stem wear Higher oil consumption and visible exhaust smoke
Installing a correct OE Match valve guide restores proper valve stem alignment, improves sealing and performance, and supports a longer engine life especially crucial during a rebuild or head service.
Replace the exhaust valve guide if you notice:
• Blue smoke indicating oil burning
• Low compression in exhaust valve tests
• Rough running or poor idle quality
• Worn valve stems or seats seen during teardown
• During head rebuild or valve seat work

Exhaust valve guides serve several key functions in the overhead valve train:
• Support and align the exhaust valve stems, ensuring they travel straight within the head.
• Maintain correct clearances between the valve stem and guide for proper sealing and combustion efficiency.
• Help transfer heat away from the hot exhaust valve stem into the cylinder head casting.
• Protect valve stems and seats from wear due to excessive lateral movement.
This set of four valve guides ensures that all exhaust valves on the 914’s four-cylinder engine have correct, matched guidance for dependable operation.
This OE Match set matches Porsche factory dimensions and is ideal for full head rebuilds, valve seat replacements or anytime guides show wear.

Cast Aluminium Bolt-On Valve Cover Upgrade Set
Upgrade your engine with this Bolt-On
Valve Cover Set, manufactured from durable cast aluminium and supplied as a
complete two-piece package with the required mounting parts and gaskets.
Fits:
- Porsche 914 (1970-1976) 1.7 / 2.0ltr
- Porsche 912E 4CYL 1976
Designed as a practical bolt-on upgrade, these cast aluminium valve covers provide a strong and durable replacement for the existing covers while giving the engine a clean, upgraded appearance.
With two valve covers, mounting hardware and gaskets included, the kit provides the essential components required for installation in one convenient package.
What Do Valve Covers Do?
Valve covers enclose and protect the upper valve train components while helping contain engine oil within the cylinder head assembly.
Their main functions include:
- Protecting valve train components from dirt and contamination
- Preventing engine oil from escaping
- Maintaining a sealed environment around the valve gear
- Supporting reliable engine operation
- Protecting internal components from external debris
A correctly fitted valve cover and gasket are essential for maintaining an effective oil seal.
Why Upgrade to Cast Aluminium Valve Covers?
Cast aluminium provides a strong and durable solution for replacing ageing or damaged original valve covers.
Benefits of upgrading include:
- Robust cast aluminium construction
- Improved durability
- Clean engine bay appearance
- Direct bolt-on installation
- New gaskets supplied
- Mounting components included
- Complete two-piece replacement set
This makes the kit particularly suitable for engine refurbishment, restoration and performance-focused builds.
Why Do Valve Covers and Gaskets Fail?
Valve covers are exposed to constant engine heat, vibration and repeated heating and cooling cycles. Over time, covers can become damaged or distorted, while the sealing gaskets gradually harden and lose their ability to maintain an effective seal.
Common problems include:
- Oil leaks around the valve cover
- Hardened or deteriorated gaskets
- Distorted sealing surfaces
- Cracked or damaged covers
- Damaged mounting points
- Previous over-tightening of mounting hardware
Oil visible around the valve cover or cylinder head area can indicate that inspection is required.
When Should They Be Replaced?
Replacement or upgrading should be considered
when:
- Valve covers are damaged or distorted
- Persistent oil leaks are present
- Existing gaskets have deteriorated
- Carrying out an engine rebuild
- Restoring or refreshing the engine
- Upgrading to stronger cast aluminium components
Installing new gaskets at the same time helps provide a fresh seal and reduces the risk of leaks from reusing ageing sealing components.
Kit
Includes
- 2 x cast aluminium valve covers
- 2 x Valve cover gaskets
- Mounting hardware parts
Cast Aluminium Valve Cover Upgrade Kits
A quality valve cover upgrade can improve both the reliability and appearance of an engine, particularly when original components have suffered from decades of heat cycles, oil contamination and previous maintenance.
This OE Match cast aluminium valve cover set provides a convenient complete solution, combining two replacement covers with new gaskets and mounting components. The robust aluminium construction makes the kit particularly suitable for restoration, engine rebuilding and preventative maintenance.
