crankshaft seal & camshaft seal of 00 odyssey

Im about to replace the timing belt and water pump of my 2000 odyssey. My question is do we need also to change the crankshaft and camshaft oil seal ?? Pls advice asap. Anything else do I need to replace ??
Thanks and waiting for response

Haven't really seen any leaking yet. One thing to look closely at is the tensioner for the T/belt. If you see any oil where the pin comes out replace it.

Just a note if the dealer says they don't have a tensioner in stock ask them to look up this number. P/N 04140-P8E-000, H/C 7593064

The 02-03 years had a recall and its a kit. Just includes an O-ring for the dipstick. But most dealers would have that rather than the tensioner by itself.
