Engine at idle speed
Avoid using the engine at idle speed or without
a load for long periods (more than 20-30

without a load, the turbocharger is at low
pressure in the exhaust chamber C and air
supply D; this may cause oil leaks from seals E
to the extremity of the shaft. Even if this does
not cause damage, it can cause blue smok

fr
om the exhaust when the engine speed and
load are increased.
