Information
Pressure ring for rocker cover.
A small sealing ring / pressure ring / rubber-grommet placed under valve-cover / rocker-cover bolts to seal the bolt hole and prevent oil from seeping past the fastener into the engine bay.
Sold each
Fits:
Porsche 944 S / 944 S2 1987 - 1991
Porsche 968 1992 - 1995
Porsche 928 S4 / 928 GT / 928 GTS 1987 - 1995
Diagram ref no 12.
This pressure ring creates a tight, oil-resistant seal around the valve-cover bolt holes, preventing leaks and keeping the cover seated properly. It maintains correct bolt clamping tension while protecting the aluminium cover from damage, and its heat-, oil- and vibration-resistant construction ensures long-term reliability under engine operating conditions. By replacing worn or hardened grommets, it restores proper sealing and supports clean, leak-free valve-cover installation during maintenance or gasket replacement.
Over time, pressure rings / bolt grommets degrade due to heat, oil exposure, and mechanical stress.
Worn seals can lead to:
• Oil seepage around valve-cover bolts
• Leaks dripping down into the engine bay or onto belts/harness
• Reduced engine bay cleanliness and potential fires in worst-case scenarios
• Difficulty obtaining proper clamping pressure when re-torquing the cover
Replacing the ring restores proper sealing, prevents future leaks, and ensures the valve cover remains securely mounted and sealed under all conditions.
When to replace - You should install new rings if:
• You are removing or replacing the valve cover or gasket
• Existing rings appear hardened, cracked, brittle, or deformed
• You notice oil leaking around valve-cover bolt heads
• You are performing engine maintenance or rebuilding the top end

Information
Crankshaft gear wheel
The crankshaft gear wheel is installed on the front of the crankshaft and is responsible for driving the timing belt system that synchronizes the rotation of the crankshaft with the camshaft. In Porsche 944 and 968 engines, this gear forms the primary drive point for the timing system, ensuring that valve timing remains precisely aligned with piston movement.
Fits:
Porsche 944 1986-1991 with engine types M 44.40 and M 44.41
Porsche 968 1992-95 with engine types M 43 and M 44.
Diagram ref no 15
This OE Match version of part number 94410512507 is designed to match the factory specifications used in Porsche engines, providing accurate tooth geometry and reliable engagement with the timing belt and associated components.
The crankshaft gear transfers rotational motion from the crankshaft to the timing belt system. This ensures the camshaft opens and closes the engine valves at the correct time relative to piston movement, maintaining proper combustion and engine performance.
If the gear becomes worn or damaged, the timing system may lose accuracy, which can affect engine efficiency and reliability.
Function
• Timing Drive: Transfers crankshaft rotation to the camshaft timing system
• Engine Synchronization: Maintains precise timing between pistons and valves
• Power Transmission: Drives the timing belt mechanism
• Engine Reliability: Ensures stable and accurate valve timing
Timing system components are subjected to constant load and engine vibration. Over time the gear teeth may wear or become damaged, which can affect timing belt alignment and engine timing accuracy. Replacing the crankshaft gear during major engine service or timing system overhaul helps ensure precise timing operation and protects other components in the engine’s timing system.
Consider replacing the crankshaft gear wheel when:
• Performing a timing belt or engine rebuild service
• Gear teeth show wear or damage
• Timing system components are being replaced
• Engine timing alignment issues are detected
