A spring loaded relief valve is integral with the dummy oil filter head mounted on the left hand side of the engine block
and prevents over pressurisation of the system.

The spin on type oil filter is mounted at the rear of the engine.
Oil flows from the filter to the main oil gallery, which runs the length of the cylinder block and also intersects the
camshaft follower chamber.
The main gallery supplies oil to the crankshaft main bearings, connecting rods and both big and small ends. The
underside of the pistons and pins, are lubricated by oil pressure jets mounted adjacent to each main journal housing.
The camshaft drive gear bushing is pressure lubricated through a drilled passage from the front main bearing. The
gear has small oil passages machined on both sides allowing excess oil to escape.
