INSPECTION AFTER INSTALLATION

Inspection of Camshaft Sprocket (EXH) Oil Groove

CAUTION:

• Perform this inspection only when DTC P0014 is detected in self-diagnostic results of CONSULT and it is directed according to inspection procedure of EC section. Refer to DTC Description. (P0014)

• Check when engine is cold so as to prevent burns by the splashing engine oil.

Check engine oil level. Refer to Inspection.

Perform the following procedure so as to prevent the engine from being unintentionally started while checking.Release the fuel pressure. Refer to Work Procedure. Remove intake manifold. Refer to Removal and Installation. Disconnect the harness connectors from the ignition coils and fuel injector. Support the bottom surface of engine using a transmission jack, and then remove the engine mounting bracket (RH) and engine mounting insulator (RH). Refer to Removal and Installation.

Remove exhaust valve timing control solenoid valve. Refer to Removal and Installation.

• Lift the front side of the engine with a jack base to remove intake or exhaust valve timing control solenoid valve.

Clean the mounting area of intake or exhaust valve timing control solenoid valve, and then insert a clean waste with no oil adhesion into the oil hole of the cylinder head.

Install engine mounting insulator (RH) and engine mounting bracket (RH). (After the removal of intake or exhaust valve timing control solenoid valve and insertion of a waste into the oil hole.)

Perform cranking to check that engine oil comes out from the oil hole (mounting hole of intake or exhaust valve timing control solenoid valve) of cylinder head.

• Regarding the engine oil check, judge it by the amount of oil adhered to the waste inserted into the oil hole.

WARNING:

• Do not insert fingers into the oil hole.

• Do not touch rotating parts (crankshaft pulley, etc.).

CAUTION:

• Do not perform cranking without installing the engine mounting insulator (RH) and engine mounting bracket (RH).

• Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil and so as to prevent engine oil contamination.

• Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to engine and Nissan Ariya vehicle. Especially, be careful not to apply engine oil to rubber parts of engine mounting insulator, etc. Wipe engine oil off immediately if it is splashed.

Perform the following inspection if engine oil does not come out from intake or exhaust valve timing control solenoid valve oil hole of the cylinder head.

• Clean oil groove between oil strainer and exhaust valve timing control solenoid valve. Refer to Engine Lubrication System.

Remove components between exhaust valve timing control solenoid valve and camshaft sprocket (EXH), and then check each oil groove for clogging.

• Clean oil groove if necessary. Refer to Engine Lubrication System.

After inspection, installation is in the reverse order removal.

INSPECTION AFTER INSTALLATION

Inspection for Leakage

The following are procedures for checking fluid leakage, lubricant leakage, and exhaust gas leakage.

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to Fluids and Lubricants.

• Use procedure below to check for fuel leakage:

  • Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.

  • Start engine. With engine speed increased, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

  NOTE:

  If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may generate a pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise will stop after hydraulic pressure rises.

• Warm up engine thoroughly to check that there is no leakage of fuel, or any oil/fluids including engine oil and engine coolant.

• Bleed air from lines and hoses of applicable lines, such as in cooling system.

• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.
