6. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve hole (A). End cranking after checking.
• Check engine oil leakage by oil amount adhered to the shop cloth inserted into the oil hole.
WARNING:
• Be careful not to touch rotating parts (drive be lts, idler pulley, and crankshaft pulley, etc.).
• Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engi ne oil contamination.
CAUTION:
• Do not perform cranking without installing right engine mount bracket, right engine mount insu-
lator, and right torque rod.
• Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful not to apply engine oil to rubber parts of drive belts,
engine mounting insulator, etc. Wipe engi ne oil off immediately if it is splashed.
7. Perform the following inspection if engine oil does not come out from intake valve timing control solenoid valve oil hole of the cylinder head.
• Remove oil filter (for intake valve timing control), and then clean it. Refer to EM-199, " Component " .
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-15 .
8. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary. Refer to LU-15 .
