I replaced mine last year as it was starting to weep a bit. where did you get your seal? what did you have to do to get the seal out? i still have the water pump and radiator in and i was hoping to not have to pull those out.

[/quote ok thanks man. when I first put it together I replace the seal that i got from an engineering shop that specializes in seals, so I wasn't sure if there was a more specific seal I need to get. this seal only has about 800 miles max on it, so I am not sure why it is leaking. looks like i'll plan on pulling the front of the engine a part soon.
