Toyota 90311-38051 Camshaft Seal

Pull off the timing belt and the sprocket of camshaft if available. Remove the bolts of the rear (No. 3) timing belt cover. Position yourself to where your eyes are looking at the centre of the bore alongside the seal, then try to pull the seal out as far away from the bore as you can see it, using a straight slot head screwdriver while be careful not to slip and scratch the bore or damage the camshaft hence causing the new seal to leak. Scrub the bore and coat the peripheral surface of the new seal with engine oil or multipurpose grease and smear the seal lip with multipurpose grease. Before replacing the seal, insert a socket having an outside diameter slightly less than the diameter of the seal into the seat of the seal with care and then drive the new seal into the place with a hammer until it is flush with the pipe and square with the socket if pipe is not available a short section of pipe can also be used. Retake the rear timing belt cover and fasten the bolts; then, replace the camshaft sprocket the single and timing belt. Lastly, start the engine and examine the region where the camshaft seal is situated for seepage of oil.
