Hi,
the video shows the sealing of the air intake system, i.e. replacing of all seals and checking all hoses on the Porsche 911 G with the 3.2 l (L-Jetronic) engine. Thus the video serves as detailed tutorial for the removal and installation of the intake manifolds, all the lines and electrical connections processed are explained individually.

The video has a German soundtrack but detailed English subtitles are available on YouTube.
Enjoy it,
Jürgen
