Engine Oil Filters (1) Engine oil filters (2) Engine oil filter change valveThe engine oil filters (1) contain six replaceable oil filter elements. There are two banks of filter elements with three filter elements in each bank. Each bank has a purge line port in order to purge the air for draining and for filling.The engine oil filter change valve (2) allows the filters for each bank to be changed separately while the engine is operating. The oil filter elements should be changed at an interval of every 1,000 hours. The oil filter elements should be changed when the oil filter bypass indicator registers a 100 kPa (14.5 psi) pressure drop. This pressure drop is measured across the filter when the engine is at operating temperature, and when the engine is running at rated speed.From the engine oil filters, the oil flows through the priority valve into the oil gallery and into the cylinder block.
