Hyundai 24110-03170 Camshaft-Intake,LH

Engines with 1.4L, 1.6L, 2011 and later 1.BL, and 2014 and later 2.0L configurations utilize small post type hydraulic lifters and rocker arms instead of shim bucket style lifters. Begin by visually inspecting the camshaft bearing surfaces for any signs of damage such as pitting, score marks, galling, or abnormal wear, as damaged surfaces necessitate cylinder head replacement. Measure the outside diameter of each camshaft bearing journal and record these measurements, then compare them to the specified journal outside diameter, followed by measuring the inside diameter of each corresponding camshaft bearing. Calculate the oil clearance by subtracting the cam journal outside diameter from the cam bearing bore inside diameter, and ensure the results fall within the specified journal-to-bearing clearance limits; if not, replacement of the camshaft or cylinder head may be required. Assess camshaft runout by placing the camshaft back into the cylinder head and using a dial indicator on the center journal, recording readings as the camshaft is turned, and if the runout exceeds specified limits, the camshaft should be replaced. Measure camshaft endplay with a dial indicator aligned with the camshaft snout, zeroing it before pushing the camshaft rearward and then forward to check the reading; excessive wear on bearing caps indicates the need for cylinder head replacement. Compare camshaft lobe heights using a micrometer, ensuring to measure each intake and exhaust lobe separately, and if the difference exceeds 0.005 inch, the camshaft should be replaced. Inspect the contact and sliding surfaces of each lifter for wear and scratches, ensuring lifters are not laid on their side or upside down to avoid trapping air, and verify that each lifter moves freely in its bore to prevent potential internal engine damage. For noisy valve lifters, run the engine to normal operating temperature, remove the valve cover, and rotate the engine until the No.1 piston is at TDC, then use a feeler gauge to measure clearance between the camshaft lobe and lifter; if clearance exceeds 0.008 inch, inspect the lifter and camshaft lobe for wear. If no clearance exists, depress the lifter to bleed it down and check again, repeating the process for remaining cylinders by following the firing order. If any clearance exceeds the maximum allowed, inspect the camshaft, and if it is in good condition, replace the faulty lifters. Ensure all parts, whether new or old, are thoroughly inspected before reassembly.

Remove the timing chain cover and timing chain. It is possible to remove the timing chain with the cover in place if you have access to special tools to release the tensioner.
