Timing chain tensioner blade
This OE Match timing chain tensioner blade is a replacement guide rail used within the engine timing chain system. It provides a controlled contact surface for the timing chain and works together with the chain tensioner to maintain correct chain position and tension.
Fits

What This Product Does
Located within the camshaft drive assembly, the blade provides a contact surface for the chain. It cooperates with the tensioning mechanism to control chain movement and support consistent tracking on applicable M96 / M97 flat-six engines.
Functions
- Supports the chain along its intended route.
- Transfers tensioner action through the blade.
- Helps limit unwanted chain movement and vibration.
- Contributes to stable camshaft drive operation.
Technical Details
- 99610515600: Left bank, cylinders 1–3.
- 99610515801: Right bank, cylinders 4–6.
Symptoms of Fault
- Rattling or slapping sounds around the chain drive.
- Visible scoring, fractures or missing sections on the blade.
- Guide fragments discovered during oil-system inspection.
- Timing deviation faults requiring further investigation.
These findings do not establish blade failure on their own; inspect the complete timing assembly before selecting replacement components.
Why Replacement Matters
Repeated chain contact, temperature changes and oil exposure can deteriorate the guiding surface. Renewing a damaged blade addresses wear at that contact point. OE Match provides a Porsche-focused replacement option, with application and specification checks forming part of its component assessment.
Consider blade renewal during chain-drive repairs, camshaft timing work or an engine rebuild when inspection identifies deterioration. Assess the chains, tensioners and neighbouring guides together rather than assuming one replacement will resolve every source of noise.
FAQs
Which reference should I select?
Match the original reference and cylinder bank: 99610515600 serves cylinders 1–3, while 99610515801 serves cylinders 4–6.
Does start-up noise prove the blade needs replacing?
No. Increasing or persistent rattling warrants diagnosis of the chain drive, including its tensioners and guides.
Should related guides be inspected?
Yes. Check adjoining timing components for wear whenever the assembly is accessible.
