DISCONNECT TURBOCHARGER OIL INLET

LINE
1. Drain all engine oil and coolant, if not previously done.
IMPORTANT: When servicing turbocharged engines
on a rollover stand, disconnect
turbocharger oil inlet line (A) from oil
filter housing or turbocharger before
rolling engine over. Failure to do so
may cause a hydraulic lock upon
starting engine. Hydraulic lock may
cause possible engine failure.
Hydraulic lock occurs when trapped oil
in the oil filter housing drains through
the turbocharger, the exhaust and
intake manifolds, and then into the
cylinder head.
After starting the engine, the trapped oil
in the manifold and head is released
into the cylinder(s) filling them with oil
causing hydraulic lock and possible
engine failure.
2. Disconnect turbocharger oil inlet line at turbocharger or
oil filter housing.
