What This Product Does
Exhaust valves open to let spent combustion gases leave the cylinders, then close against their seats to seal the combustion chambers. Their condition is relevant when investigating compression loss or assessing a cylinder head during dismantling.
Functions
- Control the passage of exhaust gases from each cylinder.
- Seal against the valve seats when closed.
- Provide replacement exhaust valves for cylinder head refurbishment.
Technical Details
- Kit contents: four exhaust valves.
- Individual valve reference: 61610540650.
- Specified engine capacity: 1.6ltr.
- The 912 assembly diagram covers 1965–69 and specifies four exhaust valves.
- The 356B / 356C assembly diagram covers 1960–1965 and identifies this valve as suitable for unleaded applications with 1600 C/SC engines.
Symptoms of Fault
Possible signs of valve sealing problems include uneven compression, persistent misfiring, irregular idling and reduced engine output. Leakage detected at the exhaust during a cylinder leak-down test can help identify an exhaust-side sealing issue. These symptoms require diagnosis rather than automatic valve replacement.
Why Replacement Matters
Renewal is appropriate when inspection identifies burnt, distorted or worn valves that no longer seal correctly. During cylinder head work, assess the seats, guides, springs and associated hardware as well: replacing valves alone does not address wear elsewhere in the assembly. Compare the four-valve contents with the planned repair before dismantling.
FAQs
What is included?
Four exhaust valves. Do not assume that guides, springs, seals or other installation components are included.
Which checks help identify valve leakage?
Compression measurements and a cylinder leak-down test help establish whether further cylinder head inspection is needed.
Does exhaust smoke confirm that valves need replacing?
No. Guide wear and other engine faults can also cause smoke, so establish the cause before selecting replacement components.

The exhaust valve controls the flow of burnt combustion gases from the cylinder into the exhaust system. Because it operates directly in the combustion chamber, it is subjected to extremely high temperatures and repeated mechanical loading every time the engine runs.
What Does the Exhaust Valve Do?
During the engine's exhaust stroke, the exhaust valve opens to allow burnt gases to leave the combustion chamber. It then closes against the valve seat to seal the cylinder for the next combustion cycle.
Correct sealing is essential for maintaining cylinder compression, efficient combustion and smooth engine performance.
Why Do Exhaust Valves Fail?
Exhaust valves operate in a particularly demanding environment because hot combustion gases pass directly across the valve head and seat.
Over time, deterioration can result from:
- Valve face or seat wear
- Excessive heat
- Burning or pitting of the valve face
- Carbon deposits
- Valve stem or guide wear
- Incorrect valve clearances
- Poor valve seating
- Corrosion during long periods of storage
A valve that no longer seals correctly can cause loss of compression and poor engine performance.
When Should It Be Replaced?
Replacement should be considered if inspection identifies a burnt, cracked, bent, excessively worn or badly pitted valve.
Possible symptoms of valve or cylinder head problems
include:
- Low cylinder compression
- Misfiring or uneven running
- Reduced engine performance
- Poor combustion
- Excessive valve train noise
- Failed compression or leak-down testing
The condition of the exhaust valves should always be assessed during a cylinder head overhaul or major engine rebuild.
Checks During Replacement
When replacing an exhaust valve, also inspect:
- Exhaust valve seat
- Valve guide
- Valve spring
- Valve collets and retainers
- Rocker arm and adjuster
- Cylinder head condition
- Remaining inlet and exhaust valves
Valve guide clearance and valve seat condition should be checked carefully before fitting a new valve.

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.
