Beav, Harvey, Trevor, experience needed

[Chicane]

My car is leaking oil from the front of the engine. Phil diagnosed this as the crank seal leaking... but the cam seals might be dripping a bit too. I'd really like to do this myself, and I'm pretty mechanically inclined, but I'm just not real familiar with a flat 6 engine. I've started reading through the manuals that Reaper put online, and it doesn't look too horibble, but I guess my biggest question is this:

What all do I have to do (to replace the crank seal and the cam seals)?

In order to REACH the crank seal, I'd have to take out the radiator (I want to get it flushed and realign the fins), waterpump, and .... then what?

I've changed heads on my 383 charger by myself before (man did that suck), and I've rebuilt a stude engine with my dad, but this is just so foreign to me. I'll also probably be doing this with my fiance's dad sometime next month, and he used to be a mechanic (went to school and everything for it), so that should help.

But any tips? I just sorta feel like I should be able to do IT, but I'm not sure exactly what IT entails.

Thanks in advance!
