- Here is a quick video I made showing you how to fill your passenger side motor mount on your E90 BMW 3 series to make it more stiff and help avoid any down pipe contact with your sub frame. I do this on my 2008 BMW 335i with the N54 motor. You could follow this guide and reinforce both mounts on any model for a better overall feel.
I use 3M Window Weld to help reinforce the mount. These are cheap mounts that can be purchase for under $30.
Search for URO 22116760330, I bought mine online from Rock Auto.
Here is a video I made showing you how to remove your mounts:

Everybody wants to talk down on improvised ‘ghetto’ fixes but no one wants to admit some of them work. Good job I’m gonna try this with my sedan ..
I took my old mounts out, cut all the rubber out and poly-filled the whole thing. Worked great.
Did this on my 09 128i after installing the rouge transmission mounts. MAJOR improvement, very minor increase in NVH. Great video, keep up the great work.
Just injected my motor mounts while doing the pan gasket and down pipes. Great collection of videos, and alot of tips put to good use. Thank you.
Thank you for sharing! Considering doing this on any new engine mount I buy for any car, seems like it'll extend working life 👍🏽
Great tip.Thanks. Keep up the good DIYs.
You’re a legend man, thank you for sharing this info.
Still working well on my n54 E92, Now I'm doing it to my E92 328xi LS swap. Ordered new mounts and will reinforce with the urethane to make sure the pan doesn't contact the steering rack due to "spongy" mounts.
awesome!! keep up the great content. I tried this with liquid polyurethane. being a complete novice it came out like concrete and my car sounds sh*t inside. lots of vibrations and bass coming though. I have new months ready but will definetly be trying this window sealer.
Awesome vid man.
your outside the box thinking reminds me of my father
keep up the the great work and ideas man...
Also works great for BMW Exhaust Hangars which tend to rip but can be permanently fixed with this method. (at least for E46)
This is what we use to do on the center bearing hanger mount lol, it seriously do work!
Nice job. Keep the vids coming.
Good to know. Changed my driver’s side mount with the IS mount due to the power steering pulley issue. Will be doing this when I have time to chain the passenger side mount.👌
About to do this as well to both my 335i and 335xi. Appreciate this vid and the other vid you show installing them!
HelpfulCarTips are you doing this for both sides ?
Rene Gonzalez yep! I will be doing it for both
@@tunerworld how’d it hold up?
@@darshkashyap9362 good! I don’t know if filling them in made any difference but car drives better with the new one on and no more pulley damage
Did this to my Buick a few years back. I wanted to get some new motor mounts for my e93 but $300+ for some new ones....no thank you. I'll be doing this very soon.
Anything to help reduce motor movement on the N5x is so important especially to avoid the serpentine belt and power steering pulley breaking from movement. When motor mounts fail, collapse, or start to have movement, the serpentine belt *WILL* start to have issues, if not very big ones. This is very good insurance. and hopefully avoids a considerable headache.
Great videos man. Keep it up.
I have a question. I both set of the mounts but they gave me both with same part number and they look identical. Is it wright? To have left and right but just facing other direction? Please can anybody help ?
Thanks
Great video! Thanks!
Great video. Can you do this on both motor mount ? or will it be too stiff if done with both motor mounts. thanks for any input
How well did it work long term V DIY? Love your detailed vids, but before I try this out, could you please give us some long term feedback 🙏
could you also use RTV gasket maker? just bought two motor mounts from rock auto for $27 each. $68 altogether. I already have a bit of black RTV gasket maker left and would think it'd be the same? or is the window seal harden more during the drying process? and are right and left mounts the same?
Any plans to drill through the plastic cap and fill up the bottom section of the mount as well?
How well does this hold up? Also, are there any other voids in other bushings that could benefit from this? I figure if I’m spending $30 on a tube and probably only using a 1/10th of it, mine as well get the $ out of it!
Very good idea.
Sorry off topic...I thought I saw your DIY on center support bearing but I can't find it. Did you take it off?
Also do you have or plan to do DIY rear differential mounts DIY?
My engine mount is directly under cat converter (like 10cm below). Since polyurethane isn’t heat resistant, is it gonna catch fire or melt? Thanks
This is great! Do you still have these installed on your 335?
before changing the engine mounts did you have vibrations inside the car? were there any symptoms the car had before changing the engine mounts? thanks!
I’m next in line to do this but now is there any excessive vibration?
I'm gonna try this for my 330i
Did you modify you cluster? Looks great
I just did this a couple of weeks ago. I had Revshift 80A Motor Mounts on both sides and it was a lot of NVH. I also had Revshift transmission mounts which added to that. So I took the driver side out and replaced with stock 335i Genuine BMW mount and filled it with this 3M stuff to see if it would reduce NVH. I might have reduced it a tiny bit. So I replaced the Revshift transmission mounts with Rogue Engineering mounts and that also helped a tiny bit with the NVH. The only thing that really stops the NVH is raising your idle speed to 900RPM.
Once the Revshift 80A passenger side mount goes south, I will replace it with the stock 335i mount with this 3M stuff and see how that feels. And I will also restore the car to stock idle RPM of 600.
How is your car holding up so far with the mounts? Still good?
You should use 335is engine mount instead of 335i
I'm going to be doing this to mine, what's the longevity like 3 years later?
If you clean old rubber bushing with acetone or toluene and fill it up with window weld, after cure you have poly bush.
What difference would that make from what he did in the vid? Wouldn’t acetone or toluene melt the rubber a little??
@@alloutofdonuts3998 It would damage it slightly, but you won't notice it. I did it due to dust and dirt. Easy way to dissolve anything. You can pressure wash them with detergent.
@@alloutofdonuts3998 I dont recommend poly bushes for diff mount (can destroy chassis) or for main part of suspension (ride way too stiff). I changed window weld bushes back to rubber. It was good experiment. 500 Nm on rear diff didn't like stiff mount. Lesson learned.
Try it with Soudal Fix All is stead of 3m Window Weld it's almost like rubber.
Good to know, thanks for the tip.
I get a slight vibration when my rpm drops does not matter the gear including N (auto) I will be giving this a try.
Did this fox the issue mate?
Do you still have these mounts? How are they holding up if so?
For my car realoem list 22116760330 for left and 22116773744 for the right. Can you confirm whether 22116760330 will fit left and right? what is the difference between the two part numbers? thanks
I thought the difference was the alignment pins that break off anyway. Maybe not, but it’s a theory lol.
Great performance mod, for a fraction of the 335is mount price!
please, can you tell me if the mount is the same for both sides? thanks
@@setterlee No, left and right are different
The Left Motor Mount Is Cheaper. Can I buy two Left Motor Mount's and use them? TIA
do these engine mounts have oil in them? i have e90 320i and i see oil leaking from passenger side engine mount and i am not sure where its coming from
How did this hold up over time
Hey I noticed your temperature gauge was reading about halfway between 160 and 250 is that normal for your car? Cuz that's what mine has been at
That's oil temp. You can see your actual coolant temp in a diagnostic menu. Lots of videos about it!
So these are holding up after two years?
What if you just put that silicone inside of your broken mounts? It should stiffen them up a bit...right?
I don’t think silicone would be as stiff plus it has to dry for a few days before adding more(like 1/4” bead at a time) unlike urethane. That would take a while. I’ve heard the mounts also collapse a bit. If that’s the case you’d be better off just getting the cheapy mounts and putting the urethane in em.
I like it. Any chance of an update on the condition of that modified mount in 2021 ?
Was literally just wondering this as changing a mates next week!
I’ve done this before and kept the car running the same mounts for about 2 years and the mounts held up really good, hence it was in my old wrx not my e92 but I was a car that was pushed to red line quite often
@@jass164 wrx doesn't make nearly as much torque as an N54 lol
Well, did your diy engineering work.....I mean after driving for 2,000 miles?
Did you get alignment after each install of new mounts?
I did not, not sure how much dropping the subframe changes the overall alignment but I do have a lifetime alignment agreement on this car so I could always double check. I didn't feel a difference after installing the mounts in terms of alignment.
@@VehicularDIY - How is it possible to have lifetime alignment on a BMW? Unless you use a nonBMW service provider like Firestone...who do not have the ability to align as per BMW best practices, and also cannot align to M3 specification if you have m3 suspension upgrades.
Even on non M3 specific alignment, BMW certified shops use weights to weigh down the car under driving conditions and then they use BMW specific alignment prongs to attach to the little holes on their wheels.
Hey I've used 3m Windo-Weld on rear diffential brand newbushings on my 2008 335i and it UTTERLY FAILED!!!
3m couldn't hold and broke out badly.
I let them dry for 5 days in AZ 110+ heat but didn't work. Filled them in all at once.
Just wondering what gives???
Somebody chime in why 3m didn't work out?
I also bought Uro motor mounts for this exact job but my confidence is slashed about the 3m.
What do you mean ‘broke out’? Did just the 3m urethane come out or did it rip the rubber part of the bushing out?
Things that come to mind, brand new bushings have mold release residue on them. Cleaning that may help. Another thought, if the urethane isn’t supported or ‘captivated’ on both sides it will not stay in. In this vid it’s filling a cavity. As opposed to just a cavity open on 2 sides. A bushing that is made specifically for an application is always supported somehow.
@@alloutofdonuts3998 Broke out i mean 3m didn't hold while new bushing held fine. I filled in the gaps and filled them all around. The new bushing is liquid filled pouches i believe and it flexed like it should. But 3m got PUNCHED THRU and broke the formation, pieces dangling.
I was very disappointed 😞
It might ok for engine mounts but differential RWD might not be good.
I push about 400hp. But from looks of things I doubt it can handle 300hp stock.
Unless it's not genuine 3m but I bought it from Amazon 3rd party seller in Las Vegas.
It got broken on the same day I test drove. You see?
I did buy new engine mounts and filled those in from left over 3m...almost 1 momth of drying now.
Did you use 3m on differential of your car? What kind of car.
@@alloutofdonuts3998 oh and I did sprayed to heck with brake cleaner. There isn't any other way to get rid of new bushing
Will you be doing trans mounts ???
I just changed them but might try out an upgraded set in the future.
So just making sure , you did this for both mounts ?
Yes but the focus should be on the passenger side.
Good video like always! Question- how’s your tranny doing? With that mileage it’s up there... I use to work on a friends bmw e90. That car had 290K on it a few years ago and it drove perfect.
Thanks! The transmission drives about as perfect as possible I'd say. It shifts like it was just made yesterday. Pretty incredible but it seems like an awesome transmission. I did the solenoids, and seals and changed the oil and filter. The fluid wasn't burnt and the clutches looked silver, no discoloration. I could see them when I dropped the valve body.
That 3
Stuff costs as much as that mount haha good shit though
So from a logic point of view, it's kind of nonsense. I need an explanation, if you're going to use the sealant, why replace it? You can spray it right in from above and drive again tomorrow. Life is extended again. Or do I understand wrong? Thanks in advance
My guess is that the downside of your solution is increased vibration in the cabin compared to original BMW mount, all things being equal. But we will never know.
lmfao i posted this few months ago on a fb post....holds my 500hp 335i so far so good...small vibration on cold days
Hey. How does it feel after more than one year? was the WindowWeld just shot out at one point?
Can anyone report back how this has lasted for them?
Really wanted to try this, but couldnt find a single comment about long-term effects. At least a dozen ppl asked... no response
in all honesty I would say you are just increasing the tendency for vibration in the car. As far as performance I would say that urethane will squeeze out of there in no time. Or sooner if oil gets in contact with it. We would do something similar to this with the W124 126 and 201 Mercedes mounts. The bottom line problem is the URO or any other Chinese made product. Aesthetically, they look sufficient, until it is installed.
Nothing in this comment makes any sense 😂
Lol @ the motor moves while cornering
maybe the engine is meant to swing in corners, you'd think there's a reason those spaces exist
Yeah it's there for a reason yeah, a bit of flex overall would feel smoother in the turns I'd think but I did this due to the limited clearance with aftermarket downpipes. There is no real advantage on a car running stock downpipes I'd say.
What a disgrace!!! Tisk tisk!!!
Ummm... Lemderfor's engine mount got Hydralic damper inside to damp certain frequency from engine... filling with some silicon doesn't help much with the original designed purpose, you may as well put some washer and rubber pads on your engine instead of using these.
