When the 944 motor has it's head or block faced, the distance between the cam gear and the crankshaft pulley is reduced. This changes the camshaft timing because the belt is in effect longer. The cam is now retarded in it's timing from stock. Avancing the cam timing has the effect of lowering the RPM at which peak power occurs. The opposite is achieved when the cam timing is retarded.

Porsche Camshaft Covers | Engine Sealing & Reliability Upgrades
Camshaft Covers seal and protect the camshaft housings, retaining engine oil while shielding vital valvetrain components from contamination. In Porsche engines, camshaft covers play a critical role in maintaining correct oil pressure, preventing leaks, and ensuring long-term valvetrain reliability—particularly in high-mileage or performance-driven vehicles.
Available from Design911, this range of Porsche camshaft covers includes upgraded and performance-focused solutions designed to improve sealing, durability, and resistance to heat-related distortion under demanding operating conditions.
What Do Camshaft Covers Do?
Camshaft covers enclose the camshaft housings and maintain a sealed lubrication environment.
Core Functions:
- Retain engine oil within the camshaft housing.
- Protect camshafts and valvetrain components.
- Maintain correct oil pressure to the top end.
- Prevent contamination from dirt and debris.
- Support reliable valve timing and operation.
Properly functioning camshaft covers are essential for engine health and efficiency.
Why Do Camshaft Covers Fail?
Over time, standard camshaft covers can degrade due to heat,
pressure, and material fatigue. Common failure causes include:
- Warping or distortion from repeated heat cycles.
- Gasket failure leading to oil leaks.
- Cracking of plastic or composite covers.
- Seal hardening due to age and temperature exposure.
- Increased crankcase pressure in tuned engines.
Failed camshaft covers can cause oil loss, misfires, and accelerated valvetrain wear.
Why Upgrade Camshaft Covers?
Upgraded camshaft covers are designed to improve durability and sealing performance.
Upgrade Benefits:
- Improved resistance to heat distortion.
- Enhanced sealing surfaces to reduce oil leaks.
- Stronger materials for long-term reliability.
- Ideal for high-mileage or performance engines.
- Supports clean, consistent top-end lubrication.
Upgrading camshaft covers helps protect the valvetrain and maintain engine performance under demanding conditions.
