Thank you spidertri. This is exactly what i was looking for. Seems like a perfect fit.

Hey, I just came across this thread and checked out FTP's solution. Looks good, but wasn't thrilled with paying international shipping cost. I did a little searching around and thought I'd offer a little additional info here. The FTP cover can be purchased from ECS Tuning or, as it turns out that BMS has an alternative, elegant solution.

BMS don't come with gasket

Again, who cares about the cover plate. It's a useless aesthetical mod that they include so they have a justification to a jacked up o-ring price.

Funnily enough I saw a video on youtube about this exact gasket yesterday:

Turns out you can't normally buy the gasket on its own but someone has started making and selling them. https://www.ebay.com.au/itm/193870641392

Where did you purchase this o-ring? Im having trouble finding one.

I just installed one of these O-rings and it still leaks from the bottom screw albeit very slowly. But overtime I am pretty sure it will be a mess unless I wipe it off after every drive. Any suggestions? I am reluctant to spend more to get aftermarket cap just to stop the leak unless that is the only way to resolve this.
thanks

O-ring plus RTV works very well.

[spidertri]

I've had mine on for over a year and never had any leaks from the cap.

I'd make sure all the old gasket material is out of the groove and clean the cap really well. Lube the seal with some fresh oil before installing the cap and make sure it stays in the groove as you install.

If that doesn't work then a little RTV like relative4 says should definitely keep it sealed.

pavjayt I've had mine in for 6 months now and it's holding up well. Key is to get the Viton ring that will be able to maintain the sealing integrity through wide range of temperature changes. I didn't use any rtv gasket.

spidertri thank you again for providing the right specs for this o-ring.

Hey guys I found this dude Matt over in Australia that is making these out of Viton.

I noticed all the other links are dead here is the new ebay link to purchase these things.

That is nice but he’s charging $19 for the gasket and $30 for shipping, so it’s $50 total.

$19 is already ridiculous but then $30 shipping for a small gasket that weighs like the same as a few pennies!?!?

For $19 shipped it **might** be worthwhile lol

If you want an actual gasket this is the only place, I've looked for days. Just posting it as an option for guys willing to pay for it. Just thought I'd help.

Well you can get 5 Viton O rings that work from Granger for $10 so why on earth would anyone pay $50 for 1?

EDIT!! That link is for wrong size!! This link below is the correct ones which are 37mm ID x 43mm OD and 3mm Viton Cross Section:

Dude, BMW literally don't even sell the gasket on it's own so no matter what you do you are technically never putting what it supposed to be there.

And you know it doesn't matter where an item is fabricated right? As long as it's what you need and meets the spec it's ok. If a viton O ring is made in China at a reputable factory it's gonna be the same shit then a viton O ring made somewhere else. Considering Grainger sells them I can assure you they are quality. Like this sa nothing to do about being cheap. In fact I'd prefer to buy something from Grainger than a random eBay seller lol but to each his own.

30$ USD to ship to Canada is an absolute fucking joke as well for a miniscule o ring that weighs nothing.

You think that a gasket from some random ebay guy, that he makes himself, is what is supposed to be in your car?

Did you even see the pictures he has up? The cuts are jagged with leftover material.

Get an o-ring from mentioned quality supplier like the rest of us and be done with it.

[SGMDream]

You guys are right, what was I thinking trying to help in any way. Take care, enjoy your cars.

Chill we just corrected you. No need to take offense when you are wrong. Enjoys your as well!

[Tallicia]

So glad to see this finally happened, could have used it 2016-2018 dealing with this. Finally had to use RTV, at least next tie can use an viton o-ring finally.

Now if only DME repairs were becoming safely openable and repaired with a little soldering and capacitor or IC swapping.

Well I ordered these and they are way too big
https://www.theoringstore.com/store/...ducts_id=27461

Do you have a link to the ones you ordered, or any leftover? I thought 6mm CS 37ID would do it, but no way in hell. They are absolutely massive.

Thanks
