DOHC engine lubrication system
1 – oil pump housing, 2 – oil pump cardan shaft with rotor, 3 – oil pump cover, 4 – oil pump sprocket, 5 – bypass valve, 6 – oil filter, 7 – gasket, 8 – oil pressure sensor, 9 – oil level indicator, 10 – oil level indicator guide, 11 – oil supply line with oil receiver, 12 – oil pan partition (oil deflector), 13 – oil pan gasket, 14 – oil pan, 15 – oil drain plug
Checking oil pressure
1. Warm up the engine to normal operating temperature.
2. Unscrew the oil pressure sensor.
3. Screw the pressure gauge nipple into its place.
4. Start the engine and check the oil pressure at idle and at 2000 rpm. Compare the obtained values with the required values (see section 3.1.4.3.1.5).
5. Disconnect the pressure gauge.
6. Screw in the oil pressure sensor.
Unscrewing the tensioner bolt of the cardan chain of the oil pump of the DOHC engine
Removal the oil pump
1. Disconnect the ground wire from the battery.
2. Remove the V-belt from the generator and coolant pump drive.
3. Unscrew the bolt securing the pulley to the crankshaft.
4. Using a puller, remove the pulley from the crankshaft.
5. Remove the lower cover of the cardan shaft of the timing chain.
6. Remove the oil pump cardan chain tensioner.
7. Remove the sprocket and chain from the oil pump shaft.
8. Remove the Torx socket bolts securing the oil pump.
9. Remove the oil pump.
Installing an oil pump
1. Check the condition and replace the oil pump gasket if necessary.
2. Install the oil pump with gasket.
3. Tighten the oil pump mounting bolts with a Torx socket.
4. Turn the pump shaft several times to suck in oil.
5. Install the oil pump sprocket (the "FRONT" mark on the sprocket should be visible from the front of the engine) together with the pump drive chain.
6. Tighten the Torx socket bolt securing the sprocket to the pump shaft.
7. Install the oil pump cardan chain tensioner.
8. Screw on the lower cover of the cardan shaft of the timing chain with a new gasket installed.
9. Place the pulley on the crankshaft.
10. Tighten the crankshaft pulley mounting bolt.
11. Install the V-belt for the generator and coolant pump drive and adjust its tension.
Checking the oil pump
1. Remove the oil pump.
2. Unscrew the Torx bolts securing the oil pump cover.
3. Remove the oil pump cover.
4. Using a feeler gauge and ruler, check the gaps between the oil pump elements.
5. Check the radial clearance between the gears.
6. Check the radial clearance between the rotor and the pump housing.
7. Check the axial clearance.
8. Remove the oil pump gears and check their condition.
9. Insert the gears into the pump body so that their markings are visible.
10. Install the oil pump cover.
11. Tighten the Torx bolts securing the oil pump cover.
12. Install the oil pump on the engine block. Other information regarding the technical characteristics, adjustment and repair of the engine is in is in subsection 4.1 and subsection 3.1.3.1.
