Engine Mounts: When Proactively Replace

elerner61 · 08-23-2022, 04:31 PM

For M owners, when are your engine mounts failing (or about to fail and you caught them in time)? $150 and two hours or so of work seems like a worthwhile project.

I did mine when I was doing the clutch in early 2020. 2007 car with 80K-something miles. The rubber showed a lot of dry cracking especially on the exhaust side. I can't say there was any indication of a problem while driving, and I would not say that they necessarily NEEDED to be replaced. But it is a 15 year old car and it is German rubber, so, yeah. I'm glad I did it.

I experienced a most unfortunate incident when I was in the wet and in first gear and went pedal down which created an unexpected rear wheel hop and it broke one of the engine mounts which created a noticeable vibration; although it was a minor vibration it was evident something was wrong and my tech found it and all is good; this was about 8 yrs ago.

I need to keep this in mind, I'm currently doing all rear bushings including diff and rear carrier sub frame bushings

my mounts are needing replacement soon on my E85, I've watched a YouTube video, it's really only expected to be 2 hours of labor? Appeared harder than that

Two different Indies charged me roughly 2 hours worth of labor the last 2 times I had them replaced. So I guessed 2 hours sound about right if you got the "right" tools?

My engine mounts look pretty tired at 91,000 mi. I'm replacing them with 034 Motorsports higher density rubber mounts,https://store.034motorsport.com/bmw/.../s54-3-2l.html
You should probably also replace your transmission mounts as well, all four are generally done at the same time, the transmission mounts can be changed out in 10 min.
