What would a knocking machine gun sound be under hood. I just started it and somewhere under the hood is a LOUD Knocking like a Machine Gun sound.


Is it metalling sound ? if that's the case then don't drive it .. you might be having issues with connecting rod or the bearings in the both cases engine will seize. Consult a auto technician, but you wont have engine light on due to this.

If it is knocking due to misfire (which is mostly the case as the engine light is also on) .... than find which cylinder have the issue then clean or replace the spark plug. If you can get a scanner to read the car computer it will solve the issue in a blink. Otherwise start the engine ... open the hood .pull out spark plug connector one by one and notice the change in sound... the one that is bad will have no effect on the sound.

My 01 gmc jimmy made a loud pop and white smoke started blowing out from under the hood. Now it makes a knocking sound but not like its low on oil or inside the motor. I dont have water in my oil and now...


The smoke under hood means that u need replace gasket between exhaust pipe and engine but smoke and knocking is not very good, it looks like your engine pistons has cracks and u r loosing oil by smoke time to time, i'd buy used engine from crashed car with less miles on it

Exhaust noise


Could be a hole in your header, you can either take off your headers completely ( pain depending on your car ) and check them for holes, or you can take it somewhere and have them checked. Other than that it could be a hole in your exhaust/exhaust manifold.

LOUD RACE CAR NOISES FROM MY 99 VW BEETLE


This seems to be a classic case of "disentegrating exhaust system syndrome." There is either a hole(s) somewhere in your exhaust system or there is a leak somewhere. Probably the easiest way to tell where the noise is coming from is to start your car and just listen around in the engine bay, under the car, and at the muffler. Also do a visual inspection of the exhaust system to see if you can see any holes in the piping. I have also seen hairline cracks in the exhaust header itself that can cause the loud ticking noise that can be a little tricky to track down.

Steering gear box knock


Lube your intermediate steering shaft. It is very easy. Remove the bolt in the shaft that you can see from under the hood and push the steering shaft up toward the firewall. Where the shaft goes into itself place some grease and work it back and forth. This will last quite a while, but is easy to do again if need be. Replace the bolt and you should be go to go. The dealer will charge you $150 to do the same job. The knock goes away as soon as you test it out.
