    hello folks.

    has anyone run across a situation where the motor of a 1998 civic rotates on
    acceleration to the point where the exhaust compression joint, just below
    the down pipe, separates and makes a 'clunk' noise? if so, or if you can
    imagine this, please tell me which motor mounts need replaced, or if a
    damper can be installed to resolve this. is this a recall or TSB by any
    chance?

    thx.
    fish.

    I am assuming that the motor mounts are my problem. Does anyone have
    experience with motor mounts? How easy are they to replace? I do quite a
    bit of work on my car, I have done shocks all around, brake work including
    replacing calipers, and also repacking a CV joint on a 1991 honda accord.
    Can someone offer up the steps required for replacing these motor mounts?
    And, would one of the motor mounts be worse off than the others?

    thanks again.

    the most important one is the rear. put it in gear [or park] and rock
    the car back & forward - you'll see it in action and can tell if it's
    faulty.

    would this be an automatic, and have you by any chance changed the
    transmission fluid? anything but honda fluid makes a dramatic
    [detrimental] difference to shift quality, and severe loading on the
    motor mounts.

    Jim,

    excellent, i will perform this check. it is automatic so i will zero in on
    the rear mount. by the way, is that rear mount on the top or bottom of the
    engine? i got a feeling its on the top.

    I think i did replace the transmission fluid on this car, and yes i drive
    straight to the dealer for the honda brand fluid.

    thank you.

    it's on the bottom, way at the back. it's a bit of a p.i.t.a. to get
    to, but is doable. the one thing that may be a problem is the big bolt
    in the center of the mount. there's not a lot of rotation room - it's
    really designed for air tool access from what i can see.

    there are also two small mounts on each side at the front, but they are
    more like bump stops than proper mounts. thye have some adjustment so
    you can try adjusting the positon of these a bit, but check the rear first.

    jim beam,

    thanks for the tips and encouragement. i will definitely perform this
    inspection and likely the repair also.

    Another way of testing is to start engine, put the car in drive, press on
    the brake and give it some gas while someone is watching under the hood. If
    you see more than 2 or 3 inches of rngine rock or movement, Jim Beam is
    correct. Replace rear motor mount.
    Good luck,
    Howard

    perfect. i have seen just that. i had an assistant rev the engine slightly
    and the engine rocked quite a bit. it seems like a simple project to
    replace the inside of that rear mount, [relatively to other projects i have
    done], so thanks for the confirmation howard.

    its my understanding that the rear mount can be repaired by replacing the
    insert, is this your understanding howard? or, do i need to replace the
    whole mount? looking at this picture in the link provided below, can you
    tell me what item number is the rear mount?
