Engine vibrate violently?

For your case, it is certianly your mounting has worn out.

 

You will feel the vibration more when your gear is engaged and less if it is neutral.

And the reason it goes up and down is because of your aircon. The aircon has a thermostat which will kick in the compressor to maintain the cold air. when that happens, it will cause more vibration. when the air is cold enough, the thermostat cut off the compressor and the impact from the vibration also reduces as a result.

 

Go change your mounting. there should be about 4 of them. Not sure how much it cost for a swift, but usually arn 200-300+ for a typical jap car.

[Mivec9]

yes there r 4 mountings...

 

maybe for his case can get the dealer do for free

[Hungryforcar]

base on what prove can convince them, the engine mount need to replace? you knw they will say it like that one, coe car mah.... on and on....

[Firstcall]

I'm not too sure but I think it's about 1k. Will check it out later, but 1k if I do not remember wrongly.

 

Only vibrate like crazy when starting, once I move off it's ok. Even when I stop at an intersection etc.

 

if your engine only vibrate during morning and not any other times, it is not engine mounting issues.

[Mivec9]

ask them to make it dun vibrate...most likely is they adjust the idling higher nia

 

get someone who can argue well along...kekeke

[Mivec9]

morning the car must warm up...

[Hungryforcar]

your gear engaged is ref to clutch in gear 1 and hold it there? or gear 1 in clutch slowly release to move without acc. tip on acc will min the vibrate, normal right

[Mivec9]

yes if accel...enuff power..sure wont vibrate

[Hungryforcar]

so not the engine mounting problem? alternative is i get mech to check then go bk to the dealer.

[Hungryforcar]

it vibrate more violently when just starting engine, then later constant vibrate but not like earthquack.

[Mivec9]

u can do latter...

 

best is get dealer to pay for the engine mount...then u will have peace of mind

[Sky8807]

hmmm..... i tap abit of acc, will reduce in vibrating but once in idlling mode, it vibrate and awhile later vibrate more and goes down, on and on, normal?

last time i own a march, the vibration is not like massage car.

i knw in the high speed it doesnt vibrate.

if the engine mounting problem can i check visually

From your descriptions, this engine is moded. probably some kind of racing cams installed. idling too low will suffer, but driving at speed is fine.

oops... didn't see the date

think he must have changed car liao...

[Yc86]

nv trust dealers..... later they just go tweak something to make the problem go away temporarily..

[Yc86]

mmmmm.... if really, can i buy over the cams?

[Hungryforcar]

dun look like the engine has modded before, but the gear shifting is quite short. rpm is quite low also. 90 km/h 2500 rpm normal or not?

[Sky8807]

camshaft mod will not affect the speed and rpm settings. rpm and speed got to do with gear ratios in the gearbox and the tyre size.

if your cam are upgraded to half or full race cams then the idle rpm cannot sustain if set too low. But once the engine is warm up, it may sustain, morning start you would have to throttle up until the engine warm up and rpm cannot be too low, I have seen those with 1700 rpm idle.

Try accel from 2500 all the way to 5000, shd be able to tell if the cam are moded, the surge is definately obvious after 3K. compared with one without the mod.
