    VS commodore
    Hey guys new to this forum.
    I recently bought a 1996 VS commodore with only 91 thousand kms. I noticed it was vibrating at idle and while accelerating at low speeds, once I reached a higher speed vibrations stopped. I've replaced all engine mounts, and transmission mount and still vibrates. Just as much if not worse. I am cometely dumbfounded.
    Your help is muchly appreciated

    Wouldn't be at all surprised if it's suffering from deteriorated inlet manifold gaskets with that fewer K's on it. I just did a set on a 98,000k car and now it starts beautifully and runs smooth as.

    I guess it all depends on how much you want to spend ? are you going to do the job yourself or get a professional to do it ?

    Some on here will say use Mace parts but all in all I feel they are a bit of overkill for your average road car. I've used Permaseal, Platinum and a few others and non have let me down so far and none have come back for rework either. If this job is done rather methodically and correctly using adequate amounts of sealer in all the corners you shouldn't have any issues.

    Commodores are very touchy when it comes to engine/gearbox mounts, even Repco rubber mounts are too harsh and can cause harmonic vibrations, I know because I chased my tail and spent a lot of money trying to get rid of harmonic vibrations.
    If at all possible fit genuine engine/gearbox mounts.
    If the vibrations is caused by a miss then seriously look at coils.

    Thanks for the reply man, I put new spark plugs and coil pack on today hasn't changed anytjing. I'm begining to believe it's either poor quality mounts or intake manifold gasket. Only thing is I'm not getting any overheating or coolant leaks.
    I've spent so much already and I'm pretty lost at the moment. Can't put my finger on it

    Don't think the intake manifold be a issue, I be getting you cylinders tested, could be a stuck exhaust valve, possibly a bad DFI, Fuel pressure. Vibrating or running rough?

    Gee Trev, you just love to discredit other members on here and have new non experienced people chasing their tails.

    Like really Trevor ! Testing Cylinders for stuck exhaust valves ????? This aint an old Briggs & Stratton on a lawnmower that's been sitting in a rusty shed for years I'm sure.

    This is another perfect scenario where you again just rub people up the wrong way and then start a pissing contest with your superior Googling skills and no actual personal experience.

    Lol, discredit get over yourself, chasing tales says the person who thinks a leak in the intake manifold would make a car shudder when there no mentioned of a coolant leak, nice try, if you want to throw around bs then don't accuse others.
    As The OP said he just brought the car so how long was it sitting for? How old is the fuel? How is the motor running? How's the transmission?
    Is the engine revving up in park without hesitation, any shaking if no then I be looking at transmission or tail shaft.
    You also haven't replaced plug leads or no mention of it.

    More Blah Blah Blah ! from the googling expert that's never worked on a car as he can't lug himself out of his chair away from his warrior keyboard.

    Don't seem to see any likes in you post directly above this one. Must mean no one agrees with you at all, as usual.

    Quote after suggestion made "Thanks for the reply man, I put new spark plugs and coil pack on today hasn't changed anytjing. I'm begining to believe it's either poor quality mounts or intake manifold gasket. Only thing is I'm not getting any overheating or coolant leaks.

    Bit of quote to reply to the last part of your statement", I put new spark plugs and coil pack on today hasn't changed anytjing."

    Unfortunatley I won't comment on what I may think the cause maybe, because there are people on here that say I have no idea on what I'm talking about

    Hey mate slight vibration at idle and take off but engine has heaps of power, no performance issues. It all started after I put rubber mounts on instead of original hydraulic mounts

    Hydraulic Mounts ??????????????????? really ????? as far as I'm aware all engine and gearbox mounts were made of vulcanised rubber and steel construction by Mackay Automotive.

    I don't know I'd call the hydraulic but they are oil fill as are some of the aftermarket options. Generally they a called typle filled, pardon the spelling.

    Then I should have one of those old Morris 1100 rear window stickers on all my VS's

    "It floats on Fluid !"

    Honestly never seen any fluid in any of my original Engine mounts on any of our 4 VS's and I've had a few of them out and re-installed them over the years as nothing was wrong with any of them. They're all Good !
