I did my own AOS, and also replaced the O-rings on the oil cooler, so I had removed both intakes.

I've managed to get the left upper intake off and replace the AOS, but now I am really struggling to get the rubber sleeves and intake back in place.
Replace stubborn "tight" rubber parts get some silicon spray lube

I haven't done this particular job myself but if you are replacing stubborn "tight" rubber parts get some silicon spray lube, it helps considerably when putting things back together.

Good luck with the rest of the repair and hopefully you are back up and running already!

I'd be leery about using silicone spray anywhere near the intake system as I have always heard that the vapors from drying silicone can cause MAF sensor failure.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The AOS went out on my car and since my garage couldn't get to it for a couple of weeks, I decided to attempt it myself. Thanks Ken on Renntech.org for the great DYI write-up. I've managed to get the left upper intake off and replace the AOS, but now I am really struggling to get the rubber sleeves and intake back in place. I've done a lot of searching and reading, but unfortunately haven't found any articles that give suggestions/advice on how to align them and re-attach everything. Any advice from this group would be greatly appreciated.
Thanks,
Nate
911 - it is a frustrating part. From my recent experience I found the following to be helpful.
1 - remove the band clamps. Unscrew all the way and install last
2 - lightly lubricate the ends of the sleeves and throttle body with some oil. This will allow you to slide the body into the sleeve mor easily
3 - try and do one side first, then gently push and twist until the other side pops in. The sleeve may get folding into the body at some point so have a small screw driver or dental pick type device to slide around the edge.
Dont give up..it can be done

I did my own AOS, and also replaced the O-rings on the oil cooler, so I had removed both intakes. I found placing the intakes in place, without the bolts, then attaching the cross rubber hoses and plenum with the bands totally loosened was the ticket. The hoses were oily, even cleaned up, so slipped on with a bit of effort, but not too bad. Far worse was getting in the bolt for the intake against the AOS.
