  Q: How do you replace the crankshaft and camshaft oil seals in 3.0L and 3.3L V6 engine on Toyota Sienna?

  A: For crankshaft oil seal removal, remove the Timing Belt and now remove the crankshaft timing belt sprocket. It is also necessary to measure the depth of the seal in the bore and then, carefully remove a part of the seal lip with the razor knife. Effectively remove the existing seal without harming the engine housing bore or the crankshaft, to avoid leakage when using a new seal; and this is best done using a screwdriver or a seal puller. Scrub the bore and lubricate the peripheral surface of the new seal with engine oil or multi-purpose grease and also spread the same grease on to the seal lip. When replacing the seal, use a seal driver or a socket slightly smaller than the seal outside diameter and Hammer the new seal into place to seating, it squarely and to the same depth as previously noted, checking that the spring is still in place. Installation of crankshaft timing sprocket and timing belt- be gentle so as not to damage the crankshaft sensor portion of the sprocket, and check for oil leaks at the front seal by running the engine. For the camshaft oil seals, first, remove the timing belt and the camshaft sprocket(s), next, unfasten the rear timing belt cover. In this case, it is usually outstanding how far the seal is seated in the bore and should be removed with a screw driver carefully while weaving a tape around the tip to prevent scratching the same. Remove the old seal using a seal button scraper or by force and then polish the bore and coat the outer circumference of the new seal with engine oil or multi-purpose grease, for the lip, apply some grease. Bash the new seal into position with the seal driver or socket so that it is in correct alignment and of the same depth as the first one. Replace the rear timing belt cover screw and torque the bolts; also replace the camshaft sprocket(s) and timing belt and start the automobile to test for oil leaks at the camshaft seal area.
