Oil Flow through The Oil Filter
Illustration 4 g00291435
Oil flow when the engine is warm.
(1) Oil manifold
(2) Oil supply line
(3) Oil return line
(4) Oil filter
(5) Bypass
(6) Oil pan
(7) Front section of the oil pump
(8) Suction lines When the engine is warm, oil comes from oil pan (6) through suction lines (8) to the front section of oil pump (7). The front section of the oil pump sends oil to the oil filter. The oil from the oil filter is sent to oil manifold (1) in the cylinder block and to oil supply line (2) for the turbocharger. Oil from the turbocharger goes back through oil return line (3) to the oil pan.

(8) Suction lines When the engine is cold, oil comes from oil pan (6) through suction lines (8). The oil is drawn into the front section of the oil pump (7) from the suction bell. When the oil is cold, an oil pressure difference in bypass valve (5) causes the valve to open. The bypass valve provides immediate lubrication to all components when cold oil with high viscosity causes a restriction to the oil flow through oil filter (4). The front section of the oil pump sends the cold oil through bypass valve (5) for the oil filter. The oil from the oil filter is sent to oil manifold (1) in the cylinder block and to oil supply line (2) for the turbocharger. Oil from the turbocharger goes back through oil return line (3) to the oil pan.When the oil is hot, an oil pressure difference in the bypass valves also causes the bypass valves to close. There is normal oil flow through the oil filter.The bypass valves will also open when there is a restriction in the oil filter. This prevents a restricted oil filter from stopping the lubrication of the engine.Oil Flow Through The Oil Cooler

Oil flow when the engine is warm and the BrakeSaver is "OFF".
(1) Oil cooler
(2) Bypass valve
(3) BrakeSaver control valve

(5) Rear section of the oil pump
(6) Oil pan
(7) Suction lines When the engine is warm, oil comes from oil pan (6) through suction lines (7) to the rear section of oil pump (5). The rear section of the oil pump sends oil to BrakeSaver control valve (3). When the BrakeSaver is in the off position, oil is sent to oil cooler (1). The oil cooler cools the hot oil. The cool oil from the oil cooler goes back through the BrakeSaver control valve to the oil pan.
