The 3.0L engine came equipped with two camshaft oil seals located on the front side (the side of the timing belt) and two camshaft oil plugs on the rear side (the side of the transaxle). That is why it is recommended to start by removing negative battery cable. Then, take off the drivebelts,
Crankshaft Pulley and the timing belt of the car. Construct a camshaft sprocket holding tool from angle iron and large bolts to hold the sprocket into place while the retain bolt is removed and once it is removed the sprocket can be lifted off by hands. It is important not to fit the wrong camshaft sprockets, and therefore it may be helpful to use an 'F' for front, and 'R' for rear fittings. If doing the front camshaft seal then unbolt the inner timing belt cover, for the rear then unbolt the alternator bracket. Although the front camshaft seal can be replaced individually it is recommended that, during this process, the O-ring situated between the distributor drive adapter and the cylinder head is also swapped. Take off the distributor and the adapter and if the adapter has been recalled, then the on vehicle seal replacement steps should not be followed instead a seal should be placed on the bench then the adapter and the distributor are put back. To remove the old seal drill, small, holes insert sheet metal screws and delicately remove the seal using a screw driver and claw hammer being careful not to cause any damage to the camshaft. For the new seal to be fitted, it is recommended that you use a large socket and an M size bolt to force it in but skipping the thread while it deforms, to prevent the camshaft from turning. In case the front cam seal was replaced, replace the inner timing belt cover too. When reinstalling the sprocket the R or F mark should face outside and the deep recess of the pulley facing towards the engine. Last but not the least ensure that the bolt is tight up to the right torque and the remaining parts replaced in a sequence starting with the last in the removal process.
