Default Shaking at idle

My N/A seems to be shaking a bit too much at idle, but only on the driver's side. It's pretty apparent when the headlights are up, because they shake visibly, especially the driver's side.

Is this a motor mount issue? Is the car safe to drive?

Yeah that's what I thought. I'm about to take the car to school with me which is an hour from my mechanic at most. Do you think I'm good to go for a couple months of light driving? I might drive it only a few miles a week haha...

also check that the balance shafts are timed correctly. it's easy to do.

it's safe to drive for short term. but don't put it off too long.

If you're judging engine vibration by looking at the headlights shaking, then before you replace the motor mounts, check to see if it's simply a loose headlight assembly. When the lights are up, grab onto the passenger side and wiggle it slightly up and down. Then the driver's side. Does the DS have any play compared to the passenger side? With your hood open, and your lights in the down position, look at the bottom of the "A" shaped bracket on the back of the light assembly. There should be a stud there (adjuster), and a rubber bumper on the underside of this stud. In the headlight 'up' position, this rubber bumper presses against the frame and stabilizes the light from vibrating.

If your steering wheel vibrates at idle, goes away with engine rev its the mounts. Mine are terrible, and I have been driving with them for a long time. On my to do list...

The real issue with the bad motor mounts is that it causes extra strain on the oil pickup tube, and if that break... A quick fix is to adjust the idle to an rpm where the vibrations stop, there is an idle adjustment screw you can screw in and out.
