hi guys, does anyone here with the RX-8 vibrate excessively change their engine mounting i was told by my workshop that the engine mounting was the cause of the vibrating problem. so, they have order the mounting for me and will change it for me in a few weeks time. jus want to check out any bro here had change the mounting and solve the problem

 

how bad is the vibration?

 

typically a vibrating car are caused by these few things:
1. mounting
2. drive shaft
3. wheel balancing

not too diff to differentite between 1/2 with 3. for 3, happens even when not accelerating and only above certain speeds. 2 is not common and only happen after many years (above 5yrs), esply if the car was lowered excessively. for mounting wear, quite common. Depending on usage (and how often your redline), typically mounting needs to be changed every 2-3 years.

How old is your 8?

 

did u install anything recently? INtake? or anything???

 

Quite bad actually u actually can feel the vibration through the steering and the seat

 

hmm...not sure abt no. 2& 3. but was told by my workshop guy that someone had the same prob as mine had the engine mounting change and solve the prob.
my 8 is abt 1 1/2 yrs now, but the prob started abt 10 mths ago

 

nope. except exhaust, but this prob started b4 i changed the exhaust. and 1 thing i notice recently is that my oil pressure moving ard 1 or slightly below when on idle. dunno whether there is a connection on the engine mounting
hopefully can solve these probs in a few week time.....

 

my view:

hmmm...that means problem started since car was 8 months old? then it might not make sense that the mounting is worn, esply when typically, rotary engines should vibrate less than piston engines. unless you drive the engine real hard all the time? if it is not the mounting, changing of the mounts may experience some improvement but not for long.

if it is still under warranty, better get it sorted out and find the root cause. hope that it's something minor and not major.

For the time being, go with the suggestion of changing mounts, see how it goes. it's like the cheapest solution at this point. take a look at the old mounts when they are removed, see whether the rubber is cracked / torn / hardened.

 

hi bro, from what i see when i open the bonnet, the engine doesn"t vibrate that excessively.
u mean when u drive hard often, the mounting will get premature wear but i thought this car is meant to drive hard :p
btw, i used to drive hard on my previous civic vtec but it still served me well for 2 1/2 yrs.
my warranty is already over, so hope nothing major hope changing of mounting help. after that me try to control not to rev hard so often :D
anyway, thks for the reply cheers....

 

I think its because the engine and gearbox are located so close to the driver position. When the combustion timing runs out of scale, you will feel the vibration. But dunno whether it has something to do with the Apex Seal. Can someone tell me wat will happen when Apex Seal is "KONG"???

Thanks

 

btw wont see diff at idle. when i said driving hard, it's just a general statement of more wear when car driven hard. nothing wrong driving hard on the 8, it's built for that, like your previous civic vtec. just remember to perform a visual inspection on the mounting when they are out from your car. hopefully all is well soon. Good luck!

 

thks bro hopefully it solve the prob after the mounting change

 

Intrega bro,

any improvements after the mount change?

 

hi bro, the parts has yet to arrive...i will update u once i've change the mounting.

 

I had the new right (passenger-side) engine mount installed on my car today. I was told by the mechanic at my dealership that this is a known issue that a tech support bulletin had recently been released on. He said according to the notice it was affecting cars at approximately 18,000 to 25,000 miles and was caused on the passenger side only because of the close proximity of the engine mount to the exhaust ports on that side of the engine. The problem can be seen if you remove the wheel and pull back the rubber splash gaurd and inspect the top portion of the engine mount for cracks. If you have the problem you would notice the car vibrating at idle. The problem was not noticeable once you had the car above 1500 RPM and where moving. The new part number for the updated mount is F151-39-040C. The original was 39-040.

 

cool bro thks for the info.

 

Ours is right hand drive cars. So the mounting is on driver's side? Intrega, can u check with you workshop?

 

check wif them already...was told they will change both the engine mounting instead of 1. by now, the parts have yet to arrive...sigh

 

Anyone knows how much it costs to change the mounts?

 

was told ard $100 for the labour, but they didn't quote me the mounts yet.

 

atl8 .....which shop did u install it at ? do they do rx8's from malaysia ? cause the shops in kl are practically useless when it comes to 8s ...

 

Integra, your mounts' been replaced yet?

 

yo bro, not yet...ask my workshop ppl why so long the parts haven't arrive, but no answer was given, keep asking me to wait. will call them again tmr...will let u know the outcome....

 

Is your a parallel import one?
If it started 10 mths ago, it should be under warranty at that time right?

Just wish to find out if the dealer will warranty the mountings.
Cos with way I am driving, I may not reach 25000km even after 3yrs and by then the 3yrs warranty offer by Mazda motor will be over.

 

Wow, i realli hope this recently released tech bulletin is the answer man!

Many of us do face the vibration problem. Mine started since dunno when... maybe couple of months after i got my ride?

Keep us posted on urs Integra. In the meantime, i will get this part number and c whether GR can get the part. Fingers X-ed this stoopid piece of mounting will solve the problem. Aint it pissing us off? esp so when we paid so freakin much for the damn car....SIGH
