For whatever reason, couldn't find specs in the Bentley manual

Thank you

Anyone have an update on the stiffer 335is engine mount after some use? Does anyone else hypothesize there could be issues with a difference in stiffness after significant wear?

Just trying to make sure I dont make more problems (uneven wear or strange vibrations) for myself later by using different materials for "engine suspension" parts.

I have slight vibration at idle.
I'm getting no vibration when first start up(about 900rpm) but start to get small vibration after engine warms up(5-600rpm).
Is this symptom of motor/transmission mount?
Easy DIY?

I have this same problem. I replaced the passenger side motor mount to no avail. I am still unsure how to get to the driver's side passenger motor mount (have an XI and there is no room). Would be curious if we come up with a solution on this.

Nobody?

Sounds like you're gonna have to drop the sub frame.

How many miles? Have you considered replacing motor mount when you do the oil pan gasket?

I'm getting the upgraded motor mounts installed today as I have the same issue. Curious to see if they solve the problem...

Does anyone have tightening torques for subframe bolts?

Followup on this.

All vibrations are completely gone. The car is now as smooth as it was when I first bought it. The mechanic said one of the motor mounts was completely shot and it was about time for new transmission mounts as well. The labour was expensive but everything worked out perfectly.

I have a weird "rattle" or clank noise on start up only, wondering if this could be motor mounts. Car has 200k on it and they are stock mounts. I do notice that if I push on the valve cover just a bit I can see the motor deflect in the engine bay.

100 percent your motor mounts are worn at that miles.

just ordered a new set. Should be installed this weekend. Will post back with my impressions. Hoping it makes a big difference

[techie182]

Have DIY for this and is it easy job?

[Neckbreaker]

great post, thx!

Get trans mounts while you are at it.

Frankly, every bushing in the car is pretty much ready to be swapped at 100k.

Still at idle I would get this odd rumble, very annoying, It had to be motor mounts, I ordered the upgraded 335is motor mounts, the passenger side is the upgraded mount as it takes the majority of the load.

I planned on installing them myself, but I didn't have a lift and after getting a excellent quote to install the mounts WAY less expensive then everywhere else from Drew, decided to have them installed.

Met up with Drew in the shop in OC, first impression, this guy knows these cars, one of the most knowledgeable guys I've talked to, you can tell he works on these cars all day, knows all there secrets most are not good

Shop had two beautiful brand new lifts just installed, a 06 E60 M5 he was replacing the SMG Clutch

Knows all the shortcuts to how to get things done on these cars fast (as most dealer techs know) dropped my front subframe casually as I was talking to him under the car like he has done it 9000 times, mounts go in no problem.

My passenger side mount was shot and had been that way for a while he estimated 70-80k there is a bump stop on the mount the motor will start to ride on when the mount goes bad, the driver side was good but I replaced it anyway.

The transmission mounts are cheaper then lunch at a fast food restaurant and a fast install so I did those as-well, they were not torn but significantly compressed and shorter then the new ones.

The car fired up SILKY SMOOTH, I don't remember the car EVER idling this smoothly, not sure what is just new mounts and what is due to the upgraded HD 335is mount.

Transmission shifting is improved more notchy, should noticed a even better difference when I do the fluid/filter soon.

I redlined the car and did not even recognize it, all the slack in the drivetrain is gone, car just goes now.

Drew went over the entire car with me, everything looked great I was particularly concerned over bushings he told me the only ones that usually go bad on e90's is the front tension struts mine looked like they just been replaced but they had not been, was shocked to hear this after reading guys from the east coast having theirs replaced at 19k. Shit roads I guess. I also slowly walk the car over driveway/ramps all the time like I'm lowered, I know people who just crash into them.

My Oil Pan is leaking which I'm likely going to have done by him, and I have a slight bend in my front wheel that you can see by looking at a fixed point on the inner part of the wheel and spinning it on the car.
