Hi,

the video shows the control of the VarioCam on the Porsche 968. VarioCam is an implementation of a variable camshaft control by Porsche. The camshafts for the intake and exhaust valves are connected by a chain. The chain is shortened by a controlled magnetic actuator and so the timing of the inlet valves changes. The system has some components that are subject to wear. The video gives you a step by step instructions for checking the timing chain, its slide rails and the camshaft gears. Porsche counts this inspection is not part of the regular service, but this inspection is recommended after 100,000 km at the latest.


The video has a German soundtrack, but English subtitles are available on YouTube.

Enjoy it,

Jürgen

I watched this yesterday, very timely because I am embarking on this inspection. There is another video referenced on replacing the chain etc, but I could not find it. Maybe same as for the 944 S2? It is a great video, higly recommended.

Hello,

the mentioned videos are in the pipeline. In three, four weeks the next video will go online. It will show the adjustment of the timing.

Greetings,

I'm always looking for good videos on the Tube about the 968. This might be the most pertinent I've come across.
