Engine Overview
The Porsche 968 968 is available with one engine variant at 239 hp.
The M44.43 is the final and most refined evolution of the Porsche transaxle four-cylinder: 3.0 litres, 16 valves, DOHC with VarioCam variable valve timing — the first Porsche production engine with variable timing. 240 hp and 305 Nm, at launch the most torquey naturally aspirated four-cylinder in its class. VarioCam pushes the torque plateau exactly where it's needed on country roads — compared to the 944 S2 the difference accelerating out of corners is immediately noticeable. More maintenance-intensive than the S2: the VarioCam guide rails (Teflon) wear and can cause tooth breakage on the camshaft sprocket — inspect every 20,000–50,000 km. Interference engine like all M44s. With complete maintenance, over 300,000 km are documented. Fully synthetic oil is mandatory — the VarioCam system is oil-pressure actuated.
- !! Timing belt failure — interference engine from 80,000 km
Same interference engine issue as all M44 engines: timing belt failure = immediate valve damage. The balance shaft belt can take the timing belt with it if it breaks. No official replacement interval — every 30,000–60,000 km recommended. Timing belt history is a key purchase factor.
Symptoms: Engine stops abruptly, cranks unusually fast on restart attempt, metallic knocking from the head - !! Balance shaft belt — secondary risk from 70,000 km
If the balance shaft belt breaks, it can wrap around the timing belt and take it with it — causing valve damage. Always replace together with the timing belt.
Symptoms: Slapping noise from the belt drive, oil traces on the belt, engine dies suddenly - !! Water pump — timing belt risk if seized from 90,000 km
A seized water pump can cause timing belt failure — catastrophic in an interference engine. The thermostat is positioned after the radiator (unusual), which makes diagnosis more difficult.
Symptoms: Temperature gauge rising, coolant loss, squealing noise from the belt drive

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Torque Tube Bearing — Transaxle Weakness Same transaxle design as the 944 — torque tube bearings wear after decades. Removal is labour-intensive; specialist refurbishment is cheaper than new OEM parts. Symptoms: Vibration under load, droning or howling from the centre tunnel, noticeable play during throttle transitions from 200,000 km | High |
