Geezus, these shops are gouging !! I never charged over 3 hours labor for AOS on manual 996 or any 986.. The 986 was much easier and almost felt guilty charging 3 hours labor on them.
996 Tiptronic is a different story, requires the intake manifold bank 1 removal and is almost easier to drop the engine..
But a 996 manual is not that bad for a pro Technician, I have never wrestled with one more than 3 hours. BTW there is no book time on this procedure, so the price" is what it is" ...If they actually remove the engine/transmission unit, then by all means address whatever needs attention..

So I need to replace my AOS. Will have my local indy do it. They're suggesting while ithe engine is out to do the IMS as well due to the labor savings. Of course this also increases the bill substantially. The issue I have is with mine being an early 98 dual row build, is this really necessary ? The failure rate for the early 99's are very low. I'm just turning 95,000 miles and you get to a point where you wonder how much makes sense to spend on a car that's 20 years old. Probably no one good answer here but thought I would throw it out there.
If the AOS will be done with engine in the car, then it doesn’t make sense. If out, well, it’s a rabbit hole. If the RMS is leaking or you need a clutch, that’s different, the IMSB might make sense because you are right there.
I would try to see i you can get the AOS done yourself or engine in the car. It’s a pain, sure, but that’s what I would try.
We have dual row bearings in our cars, and we already took a gamble on leaving it alone. Why not laugh at the IMS gods and flaunt our dual-row bearing in their faces? One of two things will happen:
1.) Karma is a b^|€£ and we deserve a failed IMSB and destroyed engine for taunting the gods and not taking the advice or pretty much everyone with any sense at all. So we pay the price, admit fault, move on.
2.) The gods can try all they want, but the early IMSB is no match. And then early cars become notable. Didn’t Apollo, with its 230,000+ miles have an original IMSB?

Certainly valid points. Seems like you have to take apart half the engine in order to replace the AOS which is why I'm not thinking this is a good idea for me.
I guess another question would be, how long should a clutch last and how do you know if it's going bad ?
My clutch seems fine, but it's one of those things where, ok the engine is out to do the AOS and at almost 100k in mileage, is it ust a matter of time before that needs to be replaced and since we're doing that, might as well do the IMS/RMS.

You might be looking at clutch, IMSB, RMS, AOS, all at the same time. I would do all of these only if the engine is healthy and doesn’t show signs of bore scoring.

$4100 is getting close to The Solution $... remember, that doing multiple jobs while your engine is out reduces the labor cost per job substantially. Don't let them quote you separate labor per job if they're doing multiple jobs at the same time. The AOS is only a $200 part - so the cost for the job is mostly labor

Maybe they are billing it as two separate jobs charging for two engine drops?

Prior owner of my car did AOS, RMS, clutch and IMS Solution via a certified installer for $4700 about 2 years ago. It’s been done for less but if you are being quoted $4100 and your car can be certified for The Solution, do it and enjoy it.
