I've done a few of these myself. The first time did take several hrs. This hose you mentioned, the best way to remove this is just to cut it and pull the AOS out. The new AOS does come with a new hose. When installing the hose make sure you use a clamp that has either a hex screw or scred driver nut to loosen/tighten.

This method saves you a lot of frustration.

+1 I also recommend the screw type clamps.

UPDATE

So I started getting a very small oil leak right after I did the AOS. From what I can tell, it's the rear main seal. I talked to my mechanic who does the stuff I can't. First, he said I saved myself a bunch of money doing it myself. He said he charges 3 hours for the project. Anyone getting it for $200 is getting a deal. He recommended that I go back and make 100% sure it's not the bottom hose from the AOS, which I'll try to tackle in the very near future. Lastly, he said that he prefers the spring clamps over the screw clamp because he said most people over tighten the screw clamps and the clamp with the hose start working their way off the engine. He's a former Porsche dealer mechanic with over 20 years experience, for what it's worth.

He even encouraged me to do the RMS myself. "If you can do the AOS, you can do the RMS." I still think I'll leave that to him when the time comes to have it done. My bruises from the AOS install are just going away.

Look very closely where the new AOS plugs into the crank. The new red seal is much harder to push in than the old style ones, if you didn't get it all the way in it could be leaking there too. I'd bet you have a small leak that is making it look like you have an RMS leak.

Keep us posted...oh and bright flashlights help find the leaky places.

^I agree! I had to do this shortly after i bought by 986 last year. I think it took me longer to get the thing with the red seal seated all the way in than it took to get the spring clamp back on!!!!! i believe i had to use a long prybar to get the leverage to push it in. i think if someone had offered to do it for $200 i would take it gladly, rather than fight with it for 5 hours myself!!! but its the same reason i did the ignition upgrade myself-to save the money and because i could.

Sorry that it's been awhile since I updated this post. It turns out that I did a great job installing the AOS (according to my mechanic). The bad news is that it's RMS. His suggestion was to wait until something else needed work like the clutch going out and try to get it all done at once. I'm going to live with 1/4 to 1/2 a quart of oil loss each month until I need to pull the trigger to get the car fixed.

Still love my Box though...
