Hi,
the video gives you a step by step tutorial how to replace the pads at the tensioner of the timing chain in your Porsche 944 S2. The timing chain connects the 2 camshaft in the 16 valves cylinder head. This repair should be done every 100000 km. A broken pad results in a serious engine damage.

The video has a German soundtrack, but English subtitles are available at YouTube. If you don't see them by default, watch the video directly at YouTube and press the subtitle button below the frame.
Enjoy it,
Jürgen
