Inspection of Camshaft Sprocket (INT) Oil Groove
WARNING:
- Check when engine is cold so as to prevent burns from any splashing engine oil.
CAUTION:
- Perform this inspection only when DTC P0011 or P0021 are detected in "DTC check" of SDT and it is directed according to inspection procedure. Refer to [P0011, P0021 IVT CONTROL ].
- Check the engine oil level. Refer to [ENGINE OIL: INSPECTION ]
- Perform the following procedure so as to prevent the engine from being unintentionally started while checking.
- Release fuel pressure. Refer to [FUEL PRESSURE CHECK: VQ40DE ]
- Disconnect ignition coil and injector harness connectors.
- Remove intake valve timing control solenoid valve. Refer to [FRONT TIMING CHAIN CASE: REMOVAL AND INSTALLATION ].
- Crank the engine, and then make sure that engine oil comes out from camshaft bracket (No. 1) oil hole. End cranking after checking.
WARNING:
- Be careful not to touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).
CAUTION:- Engine oil may squirt from intake valve timing control solenoid valve installation hole during cranking. Use a shop cloth to prevent the engine oil from spilling on components and the vehicle.
- Do not allow engine oil to get on rubber components such as drive belt or engine mount insulators. Immediately wipe off any splashed engine oil.
- Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from camshaft bracket (No. 1) oil hole. Refer to [LUBRICATION CIRCUIT ], [LUBRICATION SYSTEM: SYSTEM CHART ].
- Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT), and then check each oil groove for clogging.
- Clean oil groove if necessary. Refer to [LUBRICATION CIRCUIT ], [LUBRICATION SYSTEM: SYSTEM CHART ].
- After inspection, installation of the remaining components is in the reverse order of removal.
