Rattling noise under hood

Alright so I just came back from work and right before I get into the garage in first gear before I hit the pedal and release the clutch I heard this very disturbing rattle noise. It seemed like the hood was hitting the engine and this only happens when I'm in idle around 800 RPM's. Ok so I turned of the car, opened the hood latch and turned on the garage light and seemed fine. But then guess what I look at my right side of the motor and I see that the bolt in the motor mount is missing!! What do you guys think should I call out tommorow and fix it or can it last a few days(maybe3-5). I don't know if this is serious but I definetly don't want any more engine work due to irresponsiblity(just got the fried tranny rebuilt and changed the timing belts, water pump $1100 total). Anyways what do you guys think should I be in a hurry?

When this sound occured, had you just released the clutch in first gear? I can't remember exactly what the sound is coming from, but its completely normal. Whenever you release the clutch to move in first gear, the sound happens. I've heard it was the power steering, or the ABS system, or whatever else. But it's normal. Have no fear...unless I'm wrong...Then worry.

Yeah... Fix that ASAP. I have a friend who had an old like 93 Taurus with a bad motor mount.... he hit the gas and the thing slammed straight up into the hood so hard that it damaged the TB... the TB was WO at the time and it got stuck that way... the car was flying down the street and we couldn't take the car out of gear (A/T) because when the motor torqued upwards it misaligned with the tranny... had to turn the car off and coast to a safe (luckily) stop. He ended up needing a new hood, a new transmission, new axles, a new IM/TB, and a new radiator....

My advice... fix your mount =P

how long ago was all that work done to it? i would go back to the shop you had the work done and and get them to buy a new bolt or find another one that will work because motor mount bolts don't just fall out, either they didn't put it back in or it wasn't torqued correctly

Definetly man I think it was when they put in the water pump maybe yeah I'll go back to that place but I mean all I wanted to know was that this is what was causing that noise. So I guess yeah I'll try to hit up the shop tommorrow hope my H22 doesnt go flying lol. I mean correct me if I'm wrong but I think I have one under the motor and on the left side of the motor still left. I know that honda put 3 mounts so that if one efs up it can last at least to get to the shop to fix it and the other ones look like they're in good condition

Ok so today I had the time to open the hood a check it out so while I was checking with the car running, suprisingly, I didn't hear anything wrong. I checked the motor mounts and they were still. I gave up and closed the hood and the rattling started again. I pressed down on it and it stopped rattling.. Guess it wasn't the motor mount, Gee I still don't know what it is but I'm guessing its just the hood vibrating up n down. It only sounds when its on idle. Anybody had this problem before? I'm still going to fix the lost bolt though.

check to make sure all the bracing on the underside of the hood skin are still attached

my hood vibrates quite a bit at idle because i have motor mount inserts...it doesn't make noise, though. it gets really noticeable when the a/c is on, too.

also...another way to check for loose mounts would be to leave the car off, put it in gear and release the e-brake. make sure you're on a flat surface and with the hood open, gently push on the bumper (it's easiest to use your shin) so you can see the motor moving...look at the mounts and see if the bolts are moving along with the mount.

I had the same problem and its just the hood rattling. Open the hood and on either side of the rat there are rubber bushings you will be able to turn them (they are threded) and you can adjust the height of the bushing. That should stop the rattling. Same thing happened to me and I never heard a rattle again.

ok so I think its the aem v2 intake, it started happening right after I installed it. I heard stories about those intakes ralttling under the hood so its pretty much a coincidence. I checked it today and it doent seem to have any scratches anyways it only happenes once in a while.
