I know that timing belt changes are a common issue/post but I haven't been able to find a final verdict on this issue by searching.
Do I need to change my Crankshaft seal and Camshaft seals when I do my water pump/ TB / drivebelt change? Should I wait and see if they are worn/damaged/leaky? I am headed off in a minute and the seals are the last parts I need to start the job if I am going to do them. My 4runner is a 3.4 with 130,000 miles. Thanks. D
