Re: When must we change the Engine Mounting?
I changed my engine mounts and some tensioner thing when my 318i was about 2½ years' old. The engine was vibrating quite noticeably when the engine was idling. Must say that this is the fastest I've ever had to change engine mounts amongst all the cars I have owned.

Re: When must we change the Engine Mounting?
anyway, dun walk into the workshop telling them u want to change the engine mounting. let the workshop guys diagnose the prob for u and then u decide.
could turn out to be some other problem.instead of engine mounting.
3.5 years is not too old to warrant the change of engine mounting unless u always whack your car hard lor.

Bro
Why Shiok leh??? what did you feel that is different immediately cos like what you said, our Valvey eng Will vibrate a little even if car is new.....What is the significant change felt?
Er....what was the damage for Eng Mounting?
Thanks!

I have changed both my Engine Mounting and Control Arm Bushing.
One word "SHIOK".
But still can feel some vibration during idling but I think this is normal for Valvetronics Engine

Hi ! Simon.
The whole car feel tight and I think is the Control Arm Bushing.
As for the Engine Mounting, when you start the car, you can feel the engine don't vibrate so much but still shake during Idling. The feeling like heavy vehicle pass-by and you feel that kind of shake (The same old problem when the car is new).
Cheers

Re: When must we change the Engine Mounting?
Ok, Thanks Ben!
My control arm bush changed under warranty before already so maybe what I am feeling right now is not as much as what you were getting....But I think my eng mounting also gone liao lah...quite normal for wear and tear I guess? My mileage is 72K
Now you can LOOT away all over again! Kekeke!
Cheers!

Re: When must we change the Engine Mounting?
guess the time to change the engine and tranny mounts are about 2-4years or 60-70k km... should be due at about the second oil service per the service indicator...
looks like these mounts can last till 100k km... however, early change would be okie...

Re: When must we change the Engine Mounting?
Hmmm with regards to the engine mounting, I have owned both continental and Japanese sedans before. My 1st car a Renault, needed to have Engine mounting change within 2 yrs, but my Honda didnt vibrate enough to warrant a mounting change even after hard driving for a year before I sold it. My renault started vibrating within the 1st 10 months and got so bad that I had to change it just before it reached 2 years old.

Re: When must we change the Engine Mounting?
I read that all these rubber parts need to be changed after a number of miles. But it shouldn't follow a certain fixed period or miles. However, if money is in excess, then by all means change engine oil on every petrol top up.... If not it should be changed only when you feel its disturbing you. hehe

Re: When must we change the Engine Mounting?
Your Honda does not have an encapsulated engine. BMW's mostly encapsulate their engine to hide the noise. This encapsulation makes it really hot. But most germans are encapsulated, but BMW engines especially the valvetronic ones are really nicely efficient, and runs hot, and the engine bay is pretty small.
All this make the engine bay temps hotter than any previous BMW generations.
Hydraulic engine mounts in BMW engines pre-2006 stock has a natural rubber main spring. Exposed to extreme heat, they die very very quickly. Starting from 2007, starting with the BMW 335 only, I've read that they changed most mounts to a new tech silicone main spring. These take the heat very well, and perform much better than rubber in damping. And they will LAST up to 3-5 times longer than normal rubber mainsprings.
You just have to sit in a 335i to know how good their engine mounts are. The refinement is almost 7-series standard, perhaps better.
By the way, my experience is that engine mounts first show signs of wear when you high relatively high revs with the car shaking like hell. It could happen in any frequency range, however.

Re: When must we change the Engine Mounting?
Hmm that means more frequent replacement of the engine mountings seems more imminent. Well I gotta be lighter on the foot to minimise the acceleration of wear and tear on the mountings due to the extra heat generated from the encapsulating design of the engine.
Okie learnt something new today to cut down on maintenance costs and increase the lifespan of wear and tear parts,

BUT... you just moved from Honda to BMW. If you really wanted to save costs you'd buy a .... Civic. Ooops.
