oil leak from timing belt cover on 2004 Lexus RX330

I had my car serviced and they say I had a pretty good amount of oil from the timing belt cover. May need to replace cam & crank seal. How much should this run including parts & labor?

4.5 hours labor
timing belt 59
seals all 3 are 8 per seal.

I had my timing belt replace last year. How much will it cost to replace the seals only?

The shop that replaced the timing belt should have seen this leak when they replaced the belt. May not need the seals; it is a common problem when the pcv valve gets clogged, it forces the oil out the seals. Your shop should already know this if they work on these car regularly If they did not know this, you're going to the wrong shop!
