One of the best indicators of camshaft wear can be gotten without even having to pull the camshaft, and that is through the measurement of lobe lift. For the particularity of lifting only, some particular protocols have to be followed in the removal process. Start with the detaching of the radiator, fan, and the fan shroud. On air conditioning mounted models, loosen with a screwdriver the condenser assembly so that it comes off but the refrigerant lines need not be disconnected; to get the battery case out of the way may be necessary. Subsequently, release the distributor, if you wish, you can take out the front bumper or grille to free the camshaft and pull it out from the frontal part of the engine. Disconnect the spark plug wires and take them off and take off the cylinder head. The valve Lash Adjusters have to be removed by using magnetic pick-up tool or by a special Lash Adjuster removal tool and must be stored apart for re-use in the same bores. Disconnect the
Timing Chain and sprockets, and with some force, pull the camshaft out and if need be, temporarily put the sprocket bolt back in to act more as a handle while holding the cam to avoid scratching the bearings. Check out the Lash Adjusters to the following specifications Depending on the location of the camshaft bearing, replacement is very tricky and demands special tools, so it is recommended that the engine block be taken to automotive machine shop for the job. If the camshaft is wearing on the timing chain cover side then examine camshaft thrust pin and spring and also observe the RTV oil pressure relief hole on rear cam journal. Before inserting the camshaft into the engine, the camshaft journals and lobes must be lubricated using moly-base grease or engine assembly lube, the camshaft must be supported near the block to avoid damaging the bearings. As for removal, the installation procedure is the reverse and before starting and running the engine change the oil and filler.
