An oil distribution system for a vehicle diesel engine having a replacement oil cooler block which directs oil to a remote oil filter block. Filtered oil is routed across the supply passage of a thermostat to an oil-to-air oil cooler. Oil from the cooler is directed via a return passage to the oil cooler block for distribution to the engine. The thermostat will bypass oil directly to the return passage when the oil temperature is below a preset level. The system may be an OEM system or a retrofit modification to existing engines. The system may include multiple oil-to-air heat exchangers and may be adapted to retain existing components such as a stock oil-to-coolant oil cooler.

1. An oil filtering and cooling system in combination with a vehicle engine having a mounting location for an oil cooler on the engine, the location having existing passageways for a coolant supply, oil to be filtered and clean oil supply, the system comprising: (a) an oil cooler block having a mounting plate having passageways compatible with the existing oil passageways in the engine and a seal aligning with the existing coolant supply passageway;(b) an oil filter block having a first inlet communicating with the oil to be filtered passageway of the oil cooler block and a first outlet communicating with the clean oil in passage in the oil cooler block;(c) the oil filter block having a receptacle for an oil filter and passageways for directing oil to the filter and a second outlet for filtered oil and a second inlet for return oil;(d) a thermostat having a body having a supply passageway communicating with the oil filter block second outlet and a return passageway communicating with the oil filter block second inlet, the thermostat having a thermostatic bypass element operatively connected between the supply and return passageways to bypass oil to the return when the oil temperature is below a preset temperature, the return passageway communicating with the oil filter block; and(e) a first air-to-liquid heat exchanger having an inlet connected to the supply passage of the thermostat and an outlet connected to the return passage of the thermostat, the heat exchanger being mounted in an airflow path in a vehicle. 2. The oil filtering and cooling system of claim 1 wherein the thermostat includes a pressure responsive element to direct oil to the return passage when the pressure differential across the heat exchanger exceeds a predetermined setting. 3. The oil filtering and cooling system of claim 1 wherein the oil cooler block includes a stainless steel oil filter screen. 4. The oil filtering and cooling system of claim 1 wherein the oil cooler block has mounting holes located to conform to existing mounting locations on the engine. 5. The oil filtering and cooling system of claim 1 wherein the oil filter receptacle is threaded to receive a spin-on oil filter. 6. The oil filtering and cooling system of claim 1 further including a second air-to-liquid oil cooler connected in series with the first air-to-liquid oil cooler. 7. An oil filtering and oil cooling system in combination with a vehicle engine having a coolant-to-oil oil cooler and an oil cooler cover mounted on the engine, the oil cooler having an outlet for cooled, unfiltered oil and a return inlet for filtered oil, the system comprising: (a) an oil filter block having a first inlet communicating with the oil outlet passage of the oil cooler block;(b) the oil filter block having a receptacle for an oil filter and passageways for directing oil from the first inlet to the filter and a first outlet for filtered oil;(c) a thermostat having a body having a supply passage connected to the first outlet of the oil filter block and having a return passage connected to the oil cooler block via the filter block, the thermostat having an element to bypass oil from the supply passage to the return passage when the oil temperature is below a preset temperature; and(d) an air-to-liquid heat exchanger having an inlet connected to the supply passage of the thermostat and an outlet connected to the return passage of the thermostat, the heat exchanger being mounted in an airflow path in the vehicle. 8. A method of modifying an automotive engine having a stock coolant-to-oil oil cooler with an oil cooler cover mounted on the engine, the engine having oil supply and oil return lines, the method comprising: (a) removing the stock oil cooler and oil cooler cover from their mounting locations;(b) mounting an oil cooler block having passageways compatible with the oil passageways in the mounting location and having a seal aligned with the existing coolant supply port in the mounting location;(c) mounting an oil filter block remotely from the oil cooler block, the oil filter block having a receptacle for an oil filter, the oil filter block having a passageway communicating the oil supply with the oil filter and having a first supply outlet for filtered oil and a return oil outlet;(d) connecting the oil supply oil passage on the oil cooler block with the supply passage of the oil filter block;(e) connecting the return oil outlet on the oil filter block to the return line of the oil cooler block;(f) providing a thermostat having a body with a supply passage and a return passage with a bypass element connected between the passageways to bypass oil when the oil temperature is below a predetermined level;(g) mounting an air-to-liquid heat exchanger having an inlet and outlet in the engine area in position to receive airflow when the vehicle is operating;(h) connecting the inlet of the heat exchanger to the supply passage of the thermostat;(i) connecting the outlet of the heat exchanger to the return passage of the thermostat; and(j) connecting the return passage to the engine cooler cover via the oil filter block. 9. A method of modifying an automotive engine having a stock coolant-to-oil cooler and an oil cooler cover mounted on the engine, the engine having existing passageways for a coolant supply, oil to be cooled and cool oil return, the method comprising: (a) removing the stock oil cooler and oil cooler cover from their mounting locations;(b) mounting an oil cooler block at the mounting location of the removed stock oil cooler and cover;(c) routing a flow of oil from the engine through the oil cooler block to a remotely mounted oil filter block having a filter;(d) routing the flow of oil through the oil filter to an outlet on the oil filter block;(e) mounting a liquid-to-air heat exchanger having an inlet and an outlet at a location remote from the engine;(e) routing the flow of oil to the inlet of the liquid-to-air heat exchanger; and(h) routing the flow of oil from the liquid-to-air heat exchanger to the oil cooler block, whereby cooled filtered oil is returned to the oil return passage of the engine. 10. The method of claim 9, further comprising: providing a thermostat module disposed in a flow path between the oil filter block and the liquid-to-air heat exchanger, the thermostat module having a supply passage, an outlet, and a return passage, the thermostat module further comprising a thermostatic element disposed between the supply passage and the return passage, the thermostatic element moving from a first position in which the flow of oil is directed to the return passage toward a second position in which the flow of oil is directed to the liquid-to-air heat exchanger in response to increasing temperature of the flow of oil. 11. The method of claim 10, further comprising: providing a pressure relief element, the pressure relief element moving from a first position in which the flow of oil is directed to the liquid-to-air heat exchanger to a second position in which the flow of oil is directed to the return passage in response to increasing differential pressure between the engine oil to be cooled and the engine cool oil return. 12. The method of claim 9, wherein: The flow of oil passes through the oil filter before passing through the liquid-to-air heat exchanger. 13. The method of claim 9, wherein: the oil cooler block is mounted so that the existing passageway for the coolant supply is sealed.
