5. Connect mixing elbow to turbocharger and
tighten clamps (Figure 9-6, (6)) securely.
6. Install new gaskets and connect lubrication
return line (Figure 9-6, (4)) and supply line
(Figure 9-6, (3)).
IMPORTANT
NEVER change the length of the wastegate
control rod without doing it in coordination
with a charge pressure test. (See
Measuring Charge Pressure on page 9-7.)
Doing so will cause incorrect boost
pressure resulting in poor performance or
engine damage, and can void all warranty.
7. Install insulating cover (Figure 9-6, (2)) and
connect wastegate control rod (Figure 9-6, (1)).
8. Install air filter (Figure 9-6, (5)).
9. Start engine and check for oil leaks.
