When the crankshaft is viewed from the front of the engine, the crankshaft rotates in the following direction. ... Clockwise

When the camshaft is viewed from the front of the engine, the camshaft rotates in the following direction. ... Clockwise

The front of the engine is opposite the flywheel end of the engine. The left side of the engine and the right side of the engine are determined from the flywheel end. Number 1 cylinder is the front cylinder of the engine.

When you are lifting or moving the engine, use the following procedures in order to prevent engine damage.

1. Do not tilt the engine to an extreme angle unless the lubricating oil is first drained from the oil pan.

2. Do not turn the engine onto a side or an end surface unless the lubricating oil is first drained from the oil pan.

3. If the oil is not drained prior to tilting the engine or turning the engine onto a side or an end surface, the lubricating oil from the oil pan can enter the closed crankcase breather system and flow into the intake manifold and the cylinder bores. This situation could cause an hydraulic lock in the engine. Hydraulic lock can damage the engine.
