Tensioner spacer. Standard type not upgrade type.
Should be fitted with 93010505300 above.
The Genuine Porsche spacer sleeve is an original OEM component designed specifically for the timing chain tensioner assembly in Porsche 911 and 930 Turbo engines. It fits between the timing chain tensioner bracket and guide arm support, maintaining correct alignment and spacing in the factory timing drive geometry.

Fits:
Porsche 911 1968 - 1983
Porsche 930 Turbo

• Position on Vehicle: Inside the front timing cover area – installed in the chain/guide/tensioner zone of the flat-six engine.

• Function: Ensures precise spacing in the timing chain tensioner assembly, guaranteeing correct chain tension, optimal performance and minimal noise.

• Specification: Manufactured by Porsche, dimensioned exactly to factory tolerance, with finish and fitment that matches original componentry.

While small in size, the spacer sleeve plays a crucial role in the timing drive system:
• A missing, worn or incorrect spacer can allow the tensioner or chain guide to offset, resulting in increased slack, audible chain noise, accelerated sprocket/rail wear, or worst-case timing failure.
• Incorrect spacing may alter chain path, affect sprocket alignment and shorten component life.
• During engine rebuilds or when the timing cover is removed, it's often overlooked - but renewing this part removes a weak link in the chain drive.

When and why to replace:
•  The timing chain is noisy (chain slap) or exhibits excess play.
•  Timing cover removed for service, tensioner replaced or guide rails changed.
•  Spacer appears damaged, bent, missing or shows visible wear marks.
•  You are performing a full timing system overhaul on your Porsche 911/930 and want all components at new-spec for reliability.
