Turbo-engines with exhaust gas recirculation are
also equipped with a pressure control valve
(141 a). For space reasons this valve is installed
in the rear section of the cylinder head cover.
Note
Because of increased pressure difference
between the intake manifold and the crankcase,
a stronger compression spring (142) with a
higher spring rate was used. The following table
indicates the vehicle and engine models in which
the modified springs were first installed.in
addition to engines 602.962 and 603.970
