SET OF 12 valve guides - standard. Inlet x 6 and exhaust x 6.
This is the standard valve guide used in early air-cooled Porsche 911/930 cylinder heads. It’s a plain (non-hydraulic) guide that locates the valve stem in the head; when worn it causes oil burning, loss of compression and poor valve seating — so they’re commonly replaced whenever heads are rebuilt.
What the part is (technical data / dimensions)
Application: Porsche 911 / 930 from about 1965–1989 (varies slightly by model and year; early cars both intake & exhaust, later years sometimes exhaust only). Standard size (typical OE): ID ≈ 9.00 mm, OD ≈ 13.06 mm, length ≈ 51.2 mm.

Why these guides should be replaced
Valve guides are a wearing item. Replace them when any of the following occur or when you rebuild the engine head.Excessive valve stem play — worn guide ID internal diameter lets the valve rock and misalign with the seat , poor sealing, reduced compression and power.Oil consumption / smoking — worn guides allow oil to wick down the stem into the combustion chamber, causing blue/grey smoke and fouled plugs.Hard starting, rough idle, misfire — poor sealing / valve timing irregularities from misaligned valves.Valve wobble that leads to premature valve stem wear or valve seat damage — once stems or seats are damaged you need deeper surgery.If a guide is cracked, broken, or has excessive ovality — must be replaced.Whenever you remove and refinish seats / replace springs / do a full head rebuild — replacing guides at that time is cheap insurance and ensures correct alignment.

Valve springs endure significant thermal stress, which can cause them to lose tension over time. A broken spring can lead to severe engine damage, therefore, it's crucial to inspect and replace the springs as needed during an engine overhaul. The intake and exhaust valves use identical springs, consisting of an inner and outer spring pair for each valve. Alongside these, we offer a comprehensive selection of engine repair components, including valve stem seals and valve guides.

This valve forms a gas-tight seal against the valve seat to contain combustion pressure, then opens to allow exhaust flow out of the cylinder. Because exhaust valves operate under high heat, correct material quality and precise machining are critical for longevity and reliable sealing
A worn, pitted, or burnt exhaust valve can cause compression loss, misfires, poor performance, and potentially lead to costly cylinder head damage if ignored. Replacing valves during a rebuild helps restore correct sealing and reliable operation under heat load.
When to replace:
• Low compression / leak-down points to valve sealing issues
• Burnt valve symptoms (misfire, rough idle, power loss)
• Visible pitting, tuliping, or seat damage during teardown
• Excessive valve stem wear found during head inspection
• During cylinder head overhaul or full engine rebuild

OEMatch Engine Valves / Guides / Springs — Durability, Sealing, Performance
OEMatch supplies a selection of engine valves, valve guides and valve springs for Porsche models. These cylinder head components control air intake, exhaust flow and valve timing. Installing correct parts helps restore compression, reduce oil consumption and maintain consistent combustion across classic air-cooled flat-sixes and modern water-cooled engines.
Available Types
- Inlet (intake) valves
- Exhaust valves
- Valve guides
- Valve springs and retainers
- Valve seats and shims
Understanding OEMatch Engine Valves / Guides / Springs
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original engine valves / guides / springs.
OE (Original Equipment) refers to parts matching original specifications for the engine valves / guides / springs and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM engine valves / guides / springs engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Valves, guides and springs together control airflow into and out of the combustion chamber, maintain valve alignment and close valves with the correct force. Worn or incorrectly matched components affect sealing, timing and engine smoothness; correct selection is important for reliable operation and long-term durability. OEMatch catalogues a wide range of Porsche items, with several thousand part numbers and extensive cross-references to support rebuilds and restorations.
Benefits Include
- Restores correct airflow and combustion sealing for improved compression
- Reduces oil consumption and exhaust smoke by renewing worn guides and seals
- Eliminates valve float and restores high-RPM stability with appropriate spring rates
Why Engine Valves / Guides / Springs Wear and Fail
- Valve seat wear or pitting that reduces sealing and compression
- Burnt or bent valves from overheating or incorrect timing
- Worn valve guides causing increased clearance, oil consumption and smoke
- Fatigued or weakened valve springs leading to valve float at high engine speeds
- Corrosion and carbon build-up from poor fuel quality or many short trips
The Importance of Replacing with OEMatch Engine Valves / Guides / Springs
Timely replacement of valves, guides and springs preserves engine compression, throttle response and fuel efficiency. Renewing these components during a head rebuild or scheduled overhaul prevents secondary damage to pistons and seats, helps maintain emissions performance and keeps the engine running smoothly under load. Choosing parts selected for Porsche applications supports correct clearances, spring rates and material properties needed across different model years and engine types.
Advantages
- Direct-fit alternatives engineered to match original dimensions and tolerances where applicable
- Options suitable for restorations, routine overhauls and performance maintenance
- Components chosen for heat resistance and fatigue life to suit Porsche cylinder head conditions
