Complete list of all o-rings (by size & by part number) to buy when ordering parts
 
5 Attachment(s)
I was ordering oil filters today when I realized I should have a ready-made list of o-rings by part number to get while I'm already ordering other stuff (not just for oil changes but for all maintenance jobs).
It was untimely, while on the phone, coming up with the part numbers on the fly for optonal o-rings, so, I belatedly realized that it would have been useful to have a ready-made list all the o-rings we might wish to keep in mind to get the 'next' time we're already buying parts.

Here's my starter list below - but the point of this thread is for others to ADD other necessary maintenance o-rings (& rubber o-ring-like gaskets) for adding to existing orders and to keep in stock in the garage.

NOTE: Please make sure the part number and the size & quantity needed is listed!
  • Two small o-rings on the bottom of the oil filter stem
  • Two small o-rings at the top of the oil dipstick,
    • 11431717666, 9mm ID x2.2mm Thick (Quantity=2) $0.73 each
  • Large o-ring on oil filter cap (usually comes with the oil filter)
  • Large o-ring at the bottom of the dipstick guide tube
    • 11431740045, 19.5mm ID x3mm Thick (Quantity=1) $1.81 each
  • Power steering cap o-ring
  • Lower radiator hose coolant temperature sensor o-ring (p/n is for the air temperature sensor in the intake manifold)
    • 13621743299, 8mm ID x 3mm Thick (Quantity=1) $1.25 each
  • Oil filter housing oddly shaped gasket
  • DISA o-ring gasket
EDIT:
By way of example, here are current prices from 4wheelsautoparts (which I assume are typical out there):
Quote:

- 2 x Oil Filter Stem Seal, Lower (11427549573) = $3.64 ($1.82 each)
- 2 x Oil Dipstick Seal, Upper (11431717666) = $1.30 ($0.65 each)

- 1 x Oil Filter Kit, including O-ring, copper seal, and Mann filter (11427512300) = $4.60
- 1 x Oil Dipstick Seal, Bottom (11431740045) = $0.56
- 1 x Oil Drain Plug Bolt (11131273093) = $1.74
- 1 x Power Steering Reservoir Gasket Ring (32411128333) = $1.49

If anybody can tell me how to get the PS reservoir O-ring installed, that would be great. I cannot get it to stretch enough to sit, and stay, in the recess. And yes, the old O-ring has been removed.

Thanks!!!

Interesting thread. :thumbup: I have ignored (or more to the point, been ignorant of) these o-rings completely. Are there any recommended change intervals for these o-rings from any reputable source? I don't remember seeing any guidance in Bentley's. And I hate looking through the TIS. Mine are all probably original. Another thing(s) to replace...

I know last summer when I changed the O-rings on the distribution piece, they were hard as rock. Literally. The new ones are a tad softer - they are hard to replace.
They do deteriorate in time, sometimes it's a leak (like the oil leak by the CPS). Sometimes it's vacuum leak (DISA). BTW, Gary's O-rings work well, BUT: make sure you lube them lightly, then when you re-install the DISA, be VERY GENTLE in pressing it in. You have to actually rotate it back and forth and press it very gingerly in. Otherwise, the new O-ring will shear. Ask me how i know.
The PS O-ring, once you start seeing ATF on the canister - it's a dead givaway. I always thought it's soiled because of the vent hole. I was wrong. Since I change that sucker, I never had a drop of the red stuff staining the canister.

According to RDL in post #118 here, the BMW TIS recommends the two little o-rings on the bottom of the oil-filter-housing stem to be replaced at EVERY oil change!
- How NOT to change your oil!

I doubt anyone does it that frequently
- but it's apparently in that TIS.
All I have is this screenshot ... so if you have the TIS - let us know what it actually says.

The O-ring I bought appears to be too small and I can't get it to stay in the miniscule recess. Such a simple thing but very frustrating.

It's too cold right now to mess with any further so I'll try again later.

That's the way for most of us.

In fact, this is a picture (from this classic priming-oil-filter thread) of my very first oil change (please ignore the embarrassing $18 STP filter! I've since learned my lesson.)

Given this picture from this thread, I doubt my o-rings have EVER been changed (since I'm only the 2nd owner):

According to cn90, those two o-rings don't seem 'all' that important, functionally, though:

EDIT: I just realized that all the confusion may be due to the fact that one of these "CPS" above may actually be a CKP (crankshaft) while the other two are CPS (camshaft)!

Interestingly, here is a picture of a reputed CPS o-ring gone bad just now reported today:

EDIT: I'm very confused. I think one of these CPS's must actually be a CKP. Right?

Having had no experience with the camshaft position sensor (aka CPS) or the crankshaft position sensor (aka CKP), I'm a little confused about how many CPS o-rings are needed, as three seem to be listed - but they're all the same part number???
  • 11 Engine > 11 15 Cylinder Head > Cylinder Head Vanos
    • # 06 Intake CPS O-ring 17mm ID x 3mm thick 12141748398 $1.20 <=== am I right that these are for the camshaft
    • # 06 Exhaust CPS O-ring 17mm ID x 3mm thick 12141748398 $1.20 <=== am I right that these are for the camshaft
  • 11 Engine > 11 10 Engine Housing > Engine Block Mounting Parts

For the record, this entire thread is on the M54 engine DISA o-ring, for folks coming here the first time.

The conclusion is to use a #139 Viton O-Ring.

I just remebered last year when I replaced the PS hoses. There are 2 small O-rings p/n 17211742636 (item #11) that go to the heat exchanger.

i am too lazy to replace large o-ring on oil filter with every oil change
normally it lasts forever ( if you dont screw it ) , never oil leak from it

Thanks for that list.

It would be nice if a supplier puts together a kit for our E39s.

I can see them making a profit because, in bulk, the o-rings are pennies, whereas they can charge us a buck or so, and the kits won't take a lot of room on the shelf, and can be easily adapted for other vehicles.

By way of update, my rubber "kit" arrived today, complete with a few extra sets of the hard-to-find 441 (61610154441) wiper blade inserts and a spare oil bolt & crush washer, in addition to the list of o-rings earlier discussed in this thread, each in their own labeled baggy.

Looks like you got a new HID lamp, too.

I've attached the list I posted above, supplemented with parts listed as gasket seals and sorted by application. It's a PDF file. If anyone needs the spreadsheet, PM me.

Wow. Very nice. This is a complete 'kit' for a supplier to create for us, since most of our o-rings are a decade old by now. We could then put the kit on our garage shelf, and, whenever we're taking apart something nearby, we'd have the handy o-ring to replace.

For example, when doing the CCV, we could do the CKP and CPS o-rings, in addition to the lower dipstick tube o-ring.

You're observant! I sat down to open the box that came in the mail, and as I laid everything out to compare to the invoice, I snapped the photo, so I hadn't thought of mentioning the bulb.
I bought the bulb because my low beam indicated it was out. Funny thing - the moment I pulled the old bulb out, it lit right up in my hands.
So now I have an extra H7 bulb, just in case, to stock along with my o-rings.
Oh well, it will eventually get used (as long as I don't lose it, which I am wont to do).
Hmmmm...
Maybe we can open a separate thread, that references this thread for o-rings, that lists all the "stuff" that we can stock to put on the shelf - that our ten year old bimmers are gonna eventually need.

EDIT: I opened this thread for all "stuff" that we probably should stock in our garage:

Very hard to take them off, if you want to pull on them, which I did. I didn't use any sort of blade by fear of cutting the distribution piece, which is plastic. The O-rings for the distribution piece are p/n 11617502761 (Item #6 below)

I don't know if anyone has suggested this yet, but for the DISA, you can get square-cross-section o-rings of almost any material you like.

For example
https://www.mfpseals.com/catalog/cat...trong-nitrile-

And, of course, you can get round-cross-section o-rings at lots of places too, for the VANOS or for other parts
1. (easy to use oring warehouse calculator)
2. the o-ring store
3. mfp seals
4. orings usa

What we need is a list of the "trade sizes" for each of the replacement orings, and the material.
