Q: How to replace the Camshaft Seal and Crankshaft Seal on V6 engine on 2002 through 2006 Toyota Avalon?
A: To remove the crankshaft oil seal, remove the timing belt and sprocket. You can take out the old seal, clean the bore, and oil the seal. Use a seal driver tool for installation. Install the sprocket and belt, and check for leaks. For camshaft oil seals, remove the timing belt and sprocket. Also, remove the rear timing belt cover as well as the seal. Clean the bore, oil the new seal, and use a seal driver.
