I have not changed the DISA O-ring on my 99 528i (M5TU) yet - only the 2001 (M54)
RealOEM does show an O-ring for my M52TU but not for the M54.
The DISA P/N for the M52TU is different from M54 so that is a caution flag.
DISA O-ring for M52TU - 11617504543 - is sold here

Lol $2.31 for the o-ring and $10.50 for shipping.
Thank you for the link though
I just wasted $18 on getting the 140 seals from rocket seals. Those only work for m54 engines and not for m52 which i have. Both seals are available at the dealer M54# 11611437691 and M52# 11617504543. And they both are avaible from ECS tuning
I changed my seal but I still hear that "swoosh" sound comign from the DISA when revin the engine.
is there another place in the Disa that needs to be sealed /
I think the part # you posted for the M54 Disa valve O-ring might be the wrong one, because it looks green...

Sorry to hear that - You must have missed my post (#27) above indicating M52 DISA o-rings are different from M54.
Additionally, the P/N you provide for M54 (11611437691) is actually for M44
http://www.realoem.com/bmw/partxref....ur=&series=E36
Realoem does not have a P/N for the M54 DISA o-ring - hence the value of bimmerfiver's original post in this thread for M54 owners
i got my M52TU DISA o-ring from my local shop that received it from BMW at the astronomically high price of $2.61, and it is indeed green.
Thank you Mahmoud for posting the correct P/N for me
I have P0171 and P0174 codes. Already replaced the intake boots, but the code came back after 100 miles or so. I am thinking about replacing the DISA o-ring.
Anybody has a spare that would like to sell? Please pm if so...

Do smoke test on engine.
No more thinking or guessing.
Find the cause and source of running-lean aka vacuum leak.
Then re-read the thread.
See how some e39 engine's DISA valve o-rings are available at dealership.
See how M54 DISA valve o-ring is available at Rocket Seals.
Then purchase o-ring from dealer, on-line or directly from Rocket Seals.
It's silly to randomly replace things while hunting P0171 and P0174. I had those identical codes...and...guess what it was? My CCV (crank case vent valve). This is not my thread, but read it (and understand how it flowed pun intended and how when jlevie speaks YOU LISTEN):
http://forums.bimmerforums.com/forum....php?t=1644431
My intention of this thread was three-fold:
1). If you are doing your CCV, you have to remove your DISA Valve...and you better/best have a new DISA o-ring in-hand/in-stock. When doing your CVV I also have a thread in the DIY Section above regarding Air Intake Boot as well as the Air Distribution Piece. When doing the CCV I would replace all.
2). If by chance someone has only a DISA Valve o-ring leak, they'd know how to handle it very easily and inexpensively. Again, this thread distinguishes the o-rings and where to buy.
3). If someone at say 75K/100K miles decides to preventatively tackle things like cleaning their ICV Valve, replacing a Throttle Body gasket, replacing intake boots, assorted vacuum hoses that attach to the boot and run behind the engine...which then re-connect near the pre-cat 02 sensors (hint-hint)...they would include a $2.00 and ten minute DISA o-ring.

I just ordered these, but was not sure if you specified the encapsulated o-rings (shown in the link) or standard viton 0-rings (not encapsulated), so I ordered both. Which should I use when they arrive? I assume the non-encapsulated, but is there a problem using the encapsulated?
'05 330Ci ZHP
Please see post # 18.***
Good luck to you.
*** = In post # 18 I stress and urge and demand you use the VITON version and why? Read all of below and focus on the red.
Encapsulated PTFE w/ Viton Core O-Rings
Perfect for sealing corrosive fluids. Made with a PTFE coating that makes them virtually impervious to most solvents and chemicals. Extremely low coefficient of friction and excellent resistance to taking a set after compression, makes them ideal for static sealing application. The resin in PTFE meets L-P-389A and ASTM D-2116 requirements, and is FDA compliant. Offers greater chemical resistance than PTFE-encapsulated silicone and is recommended for long-term sealing. Durometer is Shore A: 75; temperature range is -65 to 400/500F.

~Macktheknife in my epic Jennifer Connelly OT Thread
In this post you say to use the Viton "version":
In post #18 you say to use "Viton":
2). The proper gasket for the M54 is size #140 gasket. Purchase a # 140 o-ring (buy several to stock yourself) in "VITON".
Your link described the PTFE coating but also differentiates Viton from Silicone. I got a little confused. The PFTE coated version was back ordered so i only bought the Viton o-ring. That should still work, correct?

Update: installed the disa o-ring on my m52-tu and the p/n was correct. Thank you Mahmoud! And I also replaced the giant o-ring at the junction of the MAF and air box. Mine was very flat on both articular edges. It seals much better now
As for the condition of my disa o-ring, it was flat and shrunken and definitely didn't appear to be sealing too well. I havent noticed too much of a difference but the idle seems to have smoothed out a little more. After I replace my CCV it should be rock solid.

Now instead of purchasing from Rocket Seals and going through the quoting process only to find a high shipping price... Amazon (of all places) sells the size 140 seals in 10 packs for only $8.61 with free Prime shipping or if you buy more than $25 worth of stuff.

I thought this might seem useful to someone. I'm buying a 10 pack. Feel free to PM me if you want to buy one for $1.44.

The M54 DISA O-ring is part of the DISA valve. This is why the O-ring is not sold separatly. Also a brand new M54 DISA valve has the DISA O-ring FLAT from factory, with A THIN LIP on it that will fit into a groove inside the DISA body.
An O-ring like one Keith used, will fill the flat O-ring void (after you scoop the old one out) AND the groove.
I think this piece of crap engineering was purposly build like that because of the flapper issue. If you change the O-ring expecting another 100k out of the DISA, the pin will land into the engine (because the flapper will break due to the poor design).
The safe bet is to
-either buy a new DISA (which is expensive
-do Keith's O-ring change, but then keep your eyes and especially your ears peeled for abnormal noises/codes (the elusive P0174 & P0171 - check DISA FIRST if you have a M54 engine)
-hope for the new engineered DISA repair kit which will might be available from a member from the "other" forum (I know I will).
The OEM M54 DISA O-ring is flat from factory (plus the little rib for the groove, which will be shaved off when you remove the unit)

FOR SALE -- I have an extra gasket from the company described in the original post for an M54. Just installed one on my 2005 330Ci and it fit perfectly. Mine is in the basic viton (not the encapsulted version described at the original link) and will work and perform just fine.

just called rocketseals, they want $10 each with minimum order of 8 seals.
besides the basic silicone, any other alternatives that are cheaper than $80?
i haven't reached my post limit to personal message you
Hello all:
I just wanted to say thanks to all the people who posted helpful comments here and other posts on BF regarding the DISA valve. I would like to share with you my personal experience. I tested my ticking DISA and realized the part was bad. I ordered a new one and when i removed my old one, the pin was hanging off the part and almost fill into the intake, my free advice:
PULL VERY SLOWLY ON THE DISA IF YOU THINK THE PART IS BAD, DO NOT RISK IT FALLING IN WHEN YOU ARE REPLACING THE PART!!!!!!!!!!!!!!!!!!
Just my two cents, i read on BF to pull slowly, but I didnt and it was alomost the biggest mistake.
Hope this helps remind others!!
AL
This is unacceptable.
I am going to call Rocket Seals on Monday and discuss your post with them. I am Bimmerfiver, I wear Allen Edmonds Presidio shoes, confer with OnTheFence regarding style, I will be running for Presidency in 2024 and nobody gets over on me; I am both shocked and angry to read your post as I am Mr. Rocket Seals who found them and their gaskets. I can just as easily locate the identical seals for $1.50 each, with either no minimum or minor.
If what you say is true and you are correct, you haven't been smoking dope or you aren't mistaken, I will personally and professionally address this on Monday with Rocket Seals. Is a minimum order fair? Yes. Is a million-percent increase fair on price? No.
Capitalism and Mr. Bimmerfiver will get involved on Monday. If you would like to, I suggest you send me a PM with complete details, who you spoke with, precisely what was said and what you ate for lunch that day. I have a dog in this fight and my teeth are always sharp. Nobody puts baby in a corner and nobody pushed e39 DISA's around. In your PM include your SHIP TO address. I believe I have an extra DISA o-ring and I will mail it to you for free.
EDIT: On Amazon here is a 5-pack for $6.68 total:
http://www.amazon.com/Viton--Ring-Du...6509677&sr=1-3
And GRAINGER has a 10 pack for under $8.00 total:

The shipping is what gets me. In any half decent size city you should be able to find a supplier of O rings. My supplier was out of stock, had one shipped overnight from the other side of the country and still only charged me $1.25.
