Updated as the UAOS develops. Just like Porsche does in there models, it was the best possible at the time, but as time goes on, things can be improved if you try !!

 

PT3 thanks for the info, looks like you have first class customer service ?

 

Well, I don't want any negative feelings about the UAOS. The design is solid . It's an improvement in every way over the original design and will keep many engines from "catastrophic failure"..

As with anything, material flaws and manufacturing issues will always be there, it just comes with the territory. Plan for it and take care of it as it arrises ..

As with the Infra-red monitoring system, if ANYTHING fails it set off the warning (slow flash on the dash). If the sensor fails it flashes, if the relay fails it flashes, if there is a loose connection it flashes, and of course the most important function, if the accumulation gets to dangerous level it flashes. So , as long as your don't even notice it there, you are good- to- go !!! (and never replace the Factory style AOS again)..

As far as "first class customer service" goes, I'm not so sure, the lead time of 2-4 weeks has just barely being met, so I have extended it to 4-6 weeks so not so sure that will make everyone happy.

It took 20 years to come up with a better design of the notorious failure, and probably caused many more total failures then we have previously thought, if I had thought of this 20 years ago, the reputation on the m96 would not have been quite so bad.

 

I would say with the LN Nickies, IMSS and UAOS updates like is being done on Yaz and Scotts engines in the current threads, the m96 is a solid platform.

It took 13 years for the IMSS to be invented, 20 years for the UAOS to be invented, and I can't exactly remember when the Nickies were introduced, but the evolution of the M96 is here !!

 

I was just thinking about that.
Now to improve upon water pumps and timing chains.

 

I don't worry much about timing chains and water pumps, the M96 is no worse on these parts than any other long chain/water-cooled motor.
Plus I already have Solution A and Repair B plans to handle water pump issues.

 

Hey everyone, just getting around to installing my UAOS and running into an issue with the absolute first step. How the heck do we seal the existing AOS?!?

We studied the photos and felt our way around but cannot find the breather hole for the life of us. Crazy thing is we were replacing my clutch so the transmission is out and still we're not having any luck!

We're about ready to give up by based on what most of you have said this should be the easy part!!!

Car is a 2002 with manual transmission.

 

I pulled my AOS and replaced it with a new one that was already sealed, but I don’t think you’ll be able to feel the atmospheric port.
You might feel the Ridge where it is located.

 

That’s a great pic TexSquirrel! Very clear where the port is. If the channel is filled with sealant, that should plug it shouldn’t it?

 

I can overnight you one that is already sealed !!! , wait this is saturday, UPS just closed about an hour ago. Well I can overnight you one on Monday if you want..

Smart move, I think I'm gonna start insisting a new "lifetime" re-worked Factory style AOS be purchased from me with the UAOS kit. The simple sealing of the Atmospheric Port is just causing to many issues.

Joe, you want me to put you an "already re-worked AOS" in the box with Perry's kit ?

 

Thanks for the offer Doc! I emailed you this evening

I had thought, as my AOS is still working well, that it would be a simple task to seal the port, and save all the work to actually remove the AOS. It's very difficult to see what your doing up there, and it seems that you pretty much have to go through all the steps to remove the AOS, in order to install the UAOS kit?

Yea, it would save a bunch of money and is easy for me to do, most people do not have 45 years of wrenching in tight places, so I will have to save them from themselves and just get them to buy a pre-sealed AOS with the UAOS and just have it installed...

 

My $.02


i think reaching the port to seal it from underneath for someone that has not pulled a motor from a car and knows how it is oriented is a no go. If u pull the tb and plenums the port area is very clear and easy to access. The process of sealing the port is also very easy once u can see it. I would enclose one good color print or have a dedicated web site with pics of this operation so people dont need to search for it. This would cut down on the difficulties and issues.

 

Is it possible to install the UAOS without removing the plenums? I doesn’t seem so, but thought I’d ask. I originally thought you could, but now having doubts.

 

Do we have a sense yet for hours to install UAOS by a non-expert wrench? Mine is a '99 C2 with manual transmission.
