They've installed the UAOS for customer cars but never on their track builds.

I just replaced my motorsports aos with the UAOS track version because it's just a better engineered product from a design, durability, and ability to run an extra quart of oil.

I then had the aos replaced with another oem aos and it happened again.

But let me say this, I have run a 2 quart deep sump and Motorsports AOS for over 15 years.

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.

I got one to go the opposite way, bought it thinking the passenger window/door needed a new sensor because the auto drop didn't work.
I picked up my 1998 996 today as a first time 911 owner and on the drive home I had two OMG moments. First was coolant gushing out under the car after the first 30 minutes of highway driving. Turned out is was an overfilled coolant tank.
Then I got worried by the oil pressure gauge at 5 after some spirited driving with rpms above 5000. I thought the engine was broken until I stopped and googled it...
What were your OMG experiences when you first drove your 996?
Stalling it at a stop light and trying in vain to restart not realizing you have to turn the key all the way off first to get the starter to engage, all the better with a jerk in a suv behind laying on their horn. Maybe they changed this by 996, but was the case with older ones.
First OMG moment: "What the heck is all that engine noise coming from the rear of the car.!?" There was nothing wrong but my ears and brain were calibrated to hearing engine noises coming from the front. It took me a while to adjust. I am glad I stuck with the car because it is well worth it.
A pegged oil pressure gauge at idle (cold start). A warm idle at 675 RPM. A temperature reading of 117C (HVAC hack) and last white line on the dash gauge (the 99s can do this, and DME reading was only 101C). And lastly, that the engine can�t get much more power with tuning and aftermarket mods without redesigning the insides.
First OMG moment was when the oem Aos failed on track and I had a plume of smoke that got me black flagged.
I then had the aos replaced with another oem aos and it happened again. It was then that I had my second OMG moment which was never to run an oem aos on my car ever again.

Yes, it was produced in June 1998 and according to the emission test booklet it came with, the owner tested it in July 1998.
European cars are often spec'ed by customers, then ordered from the factory and delivered later. If I understand correctly, cars in the US seems to more often be spec'ed and ordered by the dealerships.
This car was sold to Switzerland, I think 996 were sold in Europe before they were introduced to the US market.
They are considered 99's in the US, but other countries may not share the same " introductory laws"...so may be considered as "98 models" in those countries...
Why not? Would be strange -at the time - driving around in a 996 built in 1997 calling it a 1999 model.
Porsche operates with model years 1998-2005 for the 996.
Picked the car at the tag agency and drove the previous owner to his job. All the windows were down and sunroof open. Wanted the windows up and roof closed when I got on the highway� windows closed like they should but the sunroof did not. Turns out you gotta finesse the button just right but that was figured out after I got home.
VIN's with a "V" are 1997 model year, and VIN's with a "W" are 1998 model year. Not many V's exist, but there are a lot of W's produced after Sept of 1997 for the ROW market. All North America cars were designated 1999 models (X in the VIN) regardless of build year.
That's just not how models years work in the U.S. for any car. Porsche stretched '99 further than is typical with 1/98s being '99s. I don't know what is happening right now with chip shortages and what not, but ordinarily in the U.S. you could go to any dealership and buy 2023 model years now or soon.
My OMG moment was when I had first given the car some serious beans (as in 150mph on the toll road near my house) and parked it in the garage.
I walked into the garage 15 minutes later and there was this very poignant smell, a mix of rubber and gasoline and burnt plastic...
I immediately posted in a 996 facebook group and was clued in that the "Porsche perfume" I first experienced was very common and nothing to worry about.
I love the smell ever since
Bought my car from a dealership in Massachusetts, I live in Connecticut. The drive home without traffic would be close to 3 hours. About an hour into my drive home, I got a low coolant light. After pulling over for a bit, the light went off. It continued a few times and took me an extra hour and a half to get home. I kept checking temps and everything was fine. Then I worried about intermix, but there was no signs I could see. Got the car home and immediately into a shop for a Post Purchase Inspection. Seems the coolant level was just on the cusp of being too low and kept tripping the light. I had them do a coolant flush anyway and its been fine since. I had some words for the dealership though that let the car go out with the level low enough to trigger a light knowing I had a 3 hour drive ahead of me. Obviously, they did not care.
I forgot two other items from my post:
1,) The smell of my car after a track day
2.) The day I bought my car and drove 200 miles home, pulled into my driveway, and huge plumes of steam coming out the back deck lid. Turns out, the coolant cap was nowhere to be found. Simple, easy fix, thankfully.
My first thought after driving my car for the first time was "Holy Crap! This is the car they've been crapping on all these years? Did anyone actually bother to drive one before claiming it was so terrible?" Set aside the looks and the 996 is a true joy to drive.
Funny. I just spoke with a shop who builds spec boxsters and other assorted M96 based track cars. They build about 12 M96 engines a year. They run the stock AOS on all of their cars without issue. They've installed the UAOS for customer cars but never on their track builds. I don't plan on tracking my car so
All US cars were delivered as 99's. Example: mine is built in Feb of '98 before 98MY 993s and its a 99MY
Oh I remembered another.
The transmission whines. I can only hear it at low speeds, like when driving through my neighborhood with the windows down. It sounds cool - like a race car trundling through the paddock - but I�ve never heard that from any other car. I�ll choose to ignore it for now�
UAOS I think will be my second mod. First will be oil pan upgrade. I see in your signature you have the 2qt. Do you feel like the 2 qt is necessary for tracking on 200 treadwear tires? I am trying to decide if I can do the baffle for now and save the 2qt mod for if I get a little more serious on the track...
My first moment was on the test drive- "How long do you think I can make this test drive without them thinking I stole it
"
I just got my car too. So far the occasional starter whine was a surprise.
I got one to go the opposite way, bought it thinking the passenger window/door needed a new sensor because the auto drop didn't work. Turns out it just needed to be reprogrammed with holding it 'up' for 10 seconds.
75Sixer, you asked a very important question with lots of variables including: your track experience, engine condition, cooling, tires, brakes, suspension, track you will be running, time of year and air temps, length of time you will be on the track, all of which will influence the potential forces you will put your car under on the track.
If you are a novice and it's your first time on the track, you will most likely be relatively slow and your car may not be put under the oil starvation, oil pressure instability and cooling stresses that an intermediate or advanced driver may generate. But in my experience as an instructor, there is always a novice that "just gets it" and can carry more speed early on than the majority of novices. As such, the faster you are, the more you need to prepare your engine to prevent failure.
I enjoy these questions but don't want to sidetrack the intent of the thread with track set-up stuff. Maybe you can start a new thread and I will be more than happy to contribute, or pm me. But let me say this, I have run a 2 quart deep sump and Motorsports AOS for over 15 years. I just replaced my motorsports aos with the UAOS track version because it's just a better engineered product from a design, durability, and ability to run an extra quart of oil. This is huge.
IMHO, on the track, you need as much oil as you can hold in your M96 engine, and the best damn aos that can manage the oil flow.
