To take off the
Timing Belt, crankshaft, and camshaft sprockets start by taking off the inner timing belt covers together with the valve covers, and the camshaft position sensor. In the case of the non-turbocharged models between 2000 to 2005, the process of removing the rocker arm assembly entails the gradual loosening of the bolts in backward order of the sequence followed while tightening the same; the exploded components must also be stored systematically. Then, loosen and cut off the timing belt tensioner and bracket, then unbolt oil dipstick tube,alumni take off camshaft end cap assembly carefully but avoiding journal bores. For the models manufactured from 2006 onwards, provide a special spring installer tool to eliminate the spring stopper and add the lock into the intake rocker arm assembly while lifting it, and accomplish similar actions with other components. For the turbocharged models, the valve clearances have to be checked and for this the VVT oil flow control solenoid connectors have to be disconnected and for models equipped with the timing belt tensioner and oil dipstick tube has to be removed. Then, slowly take off the intake and exhaust camshaft cap assemblies, keeping all the items in order. Lifters can be removed from the cylinder heads during inspection with wear areas verified and the diameter of new and used measure in order to decide on replacements. Inspect rocker arms and camshaft parts for wearing and measuring camshaft journal diameter and lobe height; using Plastigage to determine oil clearance. Lubricate the cam shaft journals and lobes and prepare the camshaft end cap assembly with anaerobic sealant and then install the camshafts very cautiously. Correct valve overlaps with gases if necessary, as well as, applying oil and re-insertion of valve lifters and putting into considerations the right postures of the camshaft to avoid instances of valve damage. Oil number one camshaft cap sealing surface, apply sealant, oil bearing surfaces, then fasten the cap. Last, the camshaft sprockets, the timing belt and the valvetrain are put back, together with the valve covers, and new gaskets should be used, After the engine has been started, it should be examined for any unusual sounds and oil leaks.
