CAMSHAFT VALVE CLEARANCE EM-21 < PERIODIC MAINTENANCE > [VQ35DE] C D E F G H I J K L M A EM N P O • By referring to the figure, measure the valve clearances at locations marked “ × ” as shown in the table below (locations indicated in the figure). • No. 5 cylinder at compression TDC 3. Perform adjustment if the measured value is out of the standard. Refer to “ADJUSTMENT”. ADJUSTMENT • Perform adjustment depending on selected head thickness of valve lifter. Measure the valve clearance. Refer to “INSPECTION”. 2. Remove camshaft. Refer to 3. Remove valve lifters at the locations that are out of the standard. 4. Measure the center thickness of the removed valve lifters with a 5. Use the equation below to calculate valve lifter thickness for replacement. : Engine front Measuring position [bank 1 (A)] No. 1 CYL. No. 3 CYL. No. 5 CYL.
