FIGURE 4-63. ENGINE LIFTING
Carefully lift engine to desired location.
When servicing turbocharged engines on a rollover stand, disconnect
turbocharger oil inlet line from the 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 is the event that occurs when trapped oil in the oil filter
housing drains through the turbocharger, to the exhaust and intake
manifolds, and 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.
