Removing Intake Manifold

Information 

If you find leaks at the connection point between the intake manifold and turbocharger (drops of engine oil), the intake manifold and screw-type clamp must be replaced.

1. Remove the boost pressure pipe -1-  . To do this, loosen both Henn couplings -2 and 4-  . Once you have removed the boost pressure pipe, move the wire clip for the Henn coupling back into position. Loosen the spring band clamp -3-  .
