Diagram Ref No 4

The cam belt forms part of the engine timing system and helps keep the camshaft movement synchronised with engine operation. Correct camshaft timing is essential for smooth running, power delivery, fuel efficiency, and long-term engine reliability.

Functions
• Replaces the cam belt / timing belt
•  Supports correct camshaft timing
•  Helps synchronise valve train operation
•  Maintains smooth and reliable engine running
•  Replaces cracked, worn, stretched, contaminated, or aged belts
•  Suitable for scheduled timing belt service and preventative maintenance
•  OE Match replacement for Porsche 944 S / S2 and 968 engine timing service.

Why Replace This Part?
Cam belts wear with age, mileage, heat, oil contamination, tension changes, and repeated engine use. A worn or overdue cam belt can crack, fray, stretch, lose teeth, or fail without warning. Timing belt failure can cause poor running, loss of valve timing, non-start issues, or serious engine damage. Replacing the belt at the correct service interval helps protect the engine and maintain reliable performance.

When to Replace This Part
•  The timing belt service interval is due
•  The cam belt is cracked, frayed, glazed, contaminated, or worn
•  Belt teeth are damaged or missing
•  The belt has been exposed to oil, coolant, or dirt
•  Timing belt tension is incorrect or unstable
•  Tensioners, rollers, water pump, or front engine seals are being replaced
•  Preventative replacement is being carried out during major engine service.

Where it fits on the car
This cam belt fits within the engine timing belt / camshaft drive system on Porsche 944 S, 944 S2, and 968 models. It runs around the relevant camshaft and timing pulleys according to the factory timing layout.

Product Information
Cam belt
Genuine Porsche OE cam belt / timing belt for Porsche 944 S, 944 S2 and 968 models. This original Porsche toothed belt is used in the camshaft drive system on Porsche 16-valve DOHC engines, helping keep the crankshaft and camshafts correctly synchronised for accurate valve timing.

Fits:
Porsche 944 S/S2 1987 - 1991
Porsche 968 1992 - 1996

Diagram Ref No 4.

What This Part Does / Functions
•  Synchronises crankshaft and camshaft rotation
•  Maintains correct valve timing during engine operation
•  Drives the camshaft gear / camshaft timing system
•  Supports smooth running, correct combustion and engine performance
•  Helps prevent timing slip when installed and tensioned correctly
•  Provides OE Porsche tooth profile, length and fitment
•  Replaces a worn, aged, cracked or contaminated timing belt
•  Helps protect the engine from timing-related failure when serviced at the correct interval.

Why Replace This Part?
The cam belt is a critical engine service item. Over time, the belt can age, crack, stretch, wear or become contaminated by oil or coolant. If the belt slips or fails, the camshafts and crankshaft can move out of synchronisation, which may cause serious internal engine damage. Replacing it with a Genuine Porsche OE cam belt helps maintain accurate engine timing and supports the reliability of the 16-valve Porsche engine. During replacement, it is recommended to inspect the tensioners, rollers, water pump, balance shaft belt and related timing components.

When to Replace This Part
•   During scheduled timing belt service.
•   If the belt is cracked, frayed, glazed or visibly worn.
•   If the belt has been contaminated by oil, coolant or debris.
•   If the belt age or mileage is unknown.
•   When recommissioning a stored Porsche 944 S/S2 or 968
•   During camshaft, cylinder head, water pump, tensioner or roller service
•   If timing belt noise, tracking issues or tension problems are present
•   When restoring the engine with correct OE Porsche service parts

Where It Fits on the Car
This belt fits at the front of the engine, within the camshaft timing drive system. It runs around the timing pulleys and camshaft gear arrangement on the 16-valve DOHC engine.

About Engine Rebuild Kit

Complete Engine Rebuild Kits for Restoring Power, Reliability & Long-Term Performance

Engine rebuild kits provide all the essential components needed to restore, refresh or fully overhaul your Porsche engine. These kits are designed to replace worn or failing internal parts, restore proper sealing, and return the engine to optimal running condition. Whether you're addressing age-related wear, oil leaks, low compression, overheating, unusual noises or a full performance rebuild, a complete engine rebuild kit ensures every critical component is replaced with high-quality parts engineered for durability and precision.

Suitable for classic, modern and high-performance Porsche engines, these kits provide a cost-effective, reliable and comprehensive solution for both DIY engine builders and professional workshops.

What Engine Rebuild Kits Do

Engine rebuild kits play a vital role in restoring engine functionality and performance by including the major components needed to:

  • Replace worn seals and gaskets to stop leaks and restore proper sealing
  • Renew pistons, rings or bearings (depending on kit type)
  • Stabilise engine compression, improving power and efficiency
  • Rebuild top-end and bottom-end components during full overhauls
  • Restore correct oil pressure with refreshed lubrication components
  • Improve engine reliability, eliminating weak points caused by age
  • Prepare the engine for performance upgrades or forced-induction builds

A well-designed rebuild kit ensures a balanced, precise and long-lasting engine restoration.

Why Engines Fail Over Time

Even the best-engineered engines degrade due to natural wear and demanding operating conditions. Common causes of engine deterioration include:

  • Worn piston rings, leading to low compression
  • Bearing fatigue, causing bottom-end knock or oil pressure loss
  • Age-related gasket failure, resulting in oil and coolant leaks
  • Heat cycling, weakening materials and sealing surfaces
  • Poor lubrication or oil starvation, damaging internal surfaces
  • Carbon buildup, affecting combustion and valve performance
  • Overheating, causing cylinder scoring or warped components

These issues often prompt rebuilds to restore performance and prevent catastrophic engine damage.

Why You Should Replace Worn Components with a High-Quality Engine Rebuild Kit

Upgrading with a precision-engineered engine rebuild kit designed to meet or exceed original performance specifications ensures long-lasting reliability and performance.

Key benefits include:

  • Restored power and smoother engine operation
  • Proper sealing to eliminate oil leaks and coolant loss
  • Reduced oil consumption and improved combustion efficiency
  • Increased engine lifespan through refreshed internal components
  • Peace of mind for classic or high-mileage engines
  • Better performance foundation for tuning, remapping or turbo upgrades
  • Protection against future mechanical failures

A rebuild kit is the most efficient and cost-effective way to bring an ageing or troubled engine back to life.
