    Q:
    How to remove and replace the camshaft and Lash Adjuster and what precautions should be taken during reassembly in four cylinder engine on Chevrolet Malibu? Posted by Customer
    A:
    This is a difficult procedure, involving special tools. Read through the entire material and obtain the necessary tools before beginning. New camshaft sprocket bolts must be purchased for installation. Relieve the fuel system pressure. Disconnect the cable from the negative battery terminal. Remove the valve cover and high-pressure fuel pump. Remove the drive belt and drive belt tensioner. Set the engine to TDC. Remove the timing chain cover, the timing chain, and camshaft sprockets. Each camshaft cap should be marked for location and direction prior to disassembly. Loosen each bearing cap bolt slowly and evenly in reverse order of the tightening sequence. Lift the camshaft(s) from the cylinder head, parallel to the head surface. The caps must be installed in their original locations. Keep all parts from each camshaft together. Remove the rocker arms and place them in a suitable container, in order, for reinstallation. Remove the hydraulic lash adjusters from their bores in the cylinder head and store them with their corresponding rocker arms. Check each hydraulic lash adjuster for excessive wear, scoring, pitting, or an out-of-round condition. If the adjusters or the cylinder head bores are excessively worn, new adjusters or a new cylinder head, or both, may be required. Inspect the rocker arms for signs of wear or damage, particularly at the tip that contacts the valve stem, the socket that contacts the lash adjuster, and the roller that contacts the camshaft. Examine the camshaft lobes for scoring, pitting, galling, and evidence of overheating. Look for flaking of the hardened surface layer of each lobe. Measure the lobe height of each cam lobe on the intake camshaft and record your measurements. Compare the measurements for excessive variation; if the lobe heights vary more than 0.00 inch (0.125 mm), replace the camshaft. Inspect the camshaft bearing journals and the cylinder head bearing surfaces for pitting or excessive wear. Measure the diameter of each camshaft bearing journal at several points. If any journal is less than the specified minimum, replace the camshaft. Lubricate the rocker arms and hydraulic lash adjusters with engine assembly lubricant or fresh engine oil. Install the adjusters into their original bores, then install the rocker arms in their correct locations. Lubricate the camshaft(s) with camshaft installation lubricant or clean engine oil. With the camshaft notch at the front of the camshaft in the 12 o'clock position, install the camshaft into the cylinder head. Rotate the oil seal in the groove of the number one camshaft journal so the split line is at approximately the 12 o'clock position before installing the camshaft caps. Lubricate the camshaft bearing caps, then install the bearing caps into their original locations. Install the camshaft bearing cap bolts and hand-start the bolts. Tighten the bolts in sequence, a little at a time, to the torque. Install the camshaft actuator sprockets and timing chain, and the timing chain cover. The remainder of installation is the reverse of removal.
