Civic EG

ok i got a eg tat has ls in it. when i drive normal or race, the motor mount bolt always keep on losing, i tried tighting it but nothang help..
any idea whats the problem?

the big bolt that connects the bracket to the mount? are you using stock or aftermarket mounts? Do you have the lower front torque mounts installed? (some people remove them)

put some locktite on the bolts

im using the stock mount, yes the big bolt that mount to the chassis. no i dont have the lower front torque mounts.

Those lower front mounts are there for a reason, to help distribute the torque & vibrations. I would put them back in.

I took mine off too, and my rear mount bracket bolt got loose like yours and actually fell out.

I put it back in tight and it has been good since, so maybe I didn't have it tight enough the first time.

I have polyurethane filled mounts for the main sides & rear mount. But with OEM mounts, I would put the lower front mounts back on

put the torque mounts back on. that's what keep loosening your bolts.
