Toyota Camry Valve Clearance Adjustment Method

Camry valve clearance adjustment needs to go to the repair shop for adjustment. The adjustment method of Toyota Camry valve clearance is as follows: 1. Preheat the engine until the coolant temperature reaches 80℃-90℃, open the timing mark inspection holes on the clutch housing and cylinder head cover, and confirm that the cylinder head bolts are tightened to the specified torque; 2. Turn the crankshaft so that the "0" engraved line on the flywheel is aligned with the marking line on the clutch housing, and confirm that the cambered surface of the rocker arm of the intake and exhaust valve of the first cylinder is in contact with the cam base circle of the camshaft, that is, the piston of the first cylinder is at the compression top dead center (if the rocker arm is in contact with the cam, turn the crankshaft 360). At this point, the valve is in the closed position; 3. Loosen the lock nut 2 of the adjusting screw 1 and turn the adjusting screw with a screwdriver to make the gap a between the lower end face of the screw and the upper end face of the valve stem 3 reach the specified value (determined by the thickness of the thickness gauge). Keep the screwdriver still, tighten the lock nut to the specified torque, and then insert the feeler gauge into the gap A for recheck, so that the gap between the intake and exhaust valves of the first cylinder can be adjusted; 4. Then turn the crankshaft clockwise (viewed from the front of the engine). The valve clearance of the next ignition cylinder can be adjusted according to the ignition sequence of 1-3-4-2 every revolution of a 4-cylinder engine. For a 3-cylinder engine, it can be adjusted according to the ignition sequence of 1-2-3 every 240 (the rotation angle of crankshaft can be converted by the number of teeth of flywheel ring gear). Camry valve clearance adjustment needs to be carried out in the repair shop.
