Good point on the bypass hose. I did NOT replace it unfortunately. I wish I had.
On the seals, I used a small blade screwdriver and was very careful not to scratch the camshafts. I just pried them out. I was worried to. I was very gentle and at first they wouldn't come off but I finally worked them free.
I was very careful while pulling off the timing belt cover and paid close attention to where each bolt went. Great idea on what you did!
