Information
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.
Fits:

Diagram Ref No 2 and 2A.
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.
Inner diameter 9,00 mm
Outer diameter 13,06 mm
Total Length 51,20 mm

Working alongside the camshaft, valve springs, valve guides and cylinder head assembly, it ensures the precise delivery of the air-fuel mixture required for efficient combustion and optimum engine performance.
What This Product Does:
- Controls the intake of air and fuel into the combustion chamber.
- Opens and closes in precise timing with engine operation.
- Maintains an effective seal during the compression and combustion cycles.
- Supports efficient airflow and engine breathing.
- Helps maximise engine power and responsiveness.
- Contributes to fuel efficiency and emissions control.
- Forms a critical part of the engine valvetrain system.
Symptoms Of Wear Or Failure:
- Reduced engine power and performance.
- Rough idle or uneven engine operation.
- Engine misfires.Poor throttle response.
- Increased fuel consumption.
- Low compression in the affected cylinder.
- Difficulty starting the engine.
- Ticking or tapping noises from the cylinder head.
- Engine management warning lights or fault codes.
- Failed compression or leak-down test results.
Why Replacement Matters:
- Inlet valves are subjected to continuous operation and must withstand high temperatures, combustion pressures and constant airflow. Over time, valves can become worn, bent, burnt, carbon-contaminated or develop sealing issues that reduce their effectiveness and compromise engine performance.
- A damaged inlet valve can restrict airflow into the combustion chamber, resulting in poor combustion efficiency, reduced power output and increased fuel consumption. If left unresolved, valve-related problems can contribute to compression loss and cause further damage to valve seats, cylinder heads and other internal engine components.
- Replacing a worn or damaged inlet valve restores proper airflow, improves combustion efficiency and helps maintain optimal engine performance. An OE Match replacement provides factory-style fitment, precision manufacturing and long-term durability, ensuring reliable operation and helping protect your Porsche engine from premature wear and costly repairs.
