Ugh...having replaced my AOS I cringe at the thought of putting a $46 Parts Geek replacement in there with all the work required. There is something to be said for OE Porsche replacement parts, or the UAOS forever fix.

My follow up; (with thanks to everyone who made suggestions)

I tackled this job myself, after reading a number of comments stating that it wasn't that hard to do - some had completed it in a couple of hours. I ordered a new AOS, set to work, and finished up the job yesterday. )Apr 16, 2022. For anyone considering doing this replacement work yourself, here are my stats; The car was up on the jacks for about two weeks. I spent between 1 and 7 hours working on it nearly every day, since I first removed the air box. The major hang-ups for me were the alternator, the coolant tank, the gas line going to the fuel rail (I had to remove it to make room to get the coolant tank out) removing the center plenum (the second one) removing the sixth bolt at the back of the air intake plenum, loosening various coolant hoses and the rubber boot at the bottom of the old AOS, uninstalling the old AOS, installing the new AOS, reconnecting the various coolant hoses, tightening the sixth bolt on the air intake, reinstalling the coolant tank, reinstalling the alternator, and reinstalling the 2nd plenum. Everything else was easy. After all that, the car started... but is still emitting heavy white smoke. There are two possibilities here; either I screwed up the AOS during installation, somehow, or I should have gotten the problem diagnosed by a professional shop, because it now seems likely the problem wasn't the AOS at all, but score boring or something equally disastrous. I'm going to talk to the Porsche shop down the road tomorrow & get their opinion. My car is a 2001 996 .1, incidentally. Thanks again.

I have the same car, and I feel your pain. Stick with it and keep us posted. Your determination to get this done yourself is admirable. I'm hoping that my aos will hang on until I can get the uoas and have it done by my specialist. My cars going to be worth more than a new 911 at this rate. Or, I'll have spent more on it. But I'll own it, and I love it. There a certain madness involved perhaps... 🤔

Does anyone have the torque number for the two bolts that hold the engine in? (next to the engine mounts).

Thanks to all for the comments and suggestions. I didn't learn about the UAOS until I'd already ordered my standard part, so I just went with that. It seems to be working well. One further comment about the relative difficulty of doing this job; first, it's likely the mechanic doing the work (me) may not be a particularly skilled or experienced one, and (2) the job can be considerably easier or harder depending on if the car was garaged all it's life, or sat outside and was driven through, say, 20 Pennsylvania winters, versus a hanger queen. Last; if you're doing this replacement, and you're reconnecting the last few hoses, be careful when you're reattaching the tiny vacuum line that comes out from close to the starter motor. There's nothing holding it in but friction, and if you pull on it with any force, it'll come out. If you've already put the near plenum and throttle body back on, they've got to come out again, and probably the back plenum too.

Anyone know the book hours for this job?
