A bad exhaust manifold gasket could do that.
Listen to it. if it is making loud noise you will hear it... assuming by noise you mean sound wave vibrations within the range of human detection...
Loud exhaust noise from the front end is usually caused by one of several problems. The exhaust manifold gasket could be blown, the doughnut gasket could be bad, or there could be a crack in the exhaust itself.
have you checked to see if there is any broken bolt on the manifold, or worped manifold, burnt manifold gasket
manifold or downpipe gaskets may be leaking gases or worse, cracked manifold
Loud engine noise is usually a result of a hole or disconnection in the exhaust manifold or muffler.
If it is the intake manifold, there will be vacuum leaks, backfire, and poor performance. If it is the exhaust manifold, you will have loud exhaust noise which may warrant a citation - also, emissions control laws will be violated. Take the manifold ro a shop where it can be re-surfaced or try to find a product at your local auto parts store that will help seal the manifold. - Good luck.
If it's the intake manifold, the car won't run very well - if at all. The exhaust manifold will make a loud noise and you should be able to smell the fumes under the hood. Also, it will most probably make a snapping and popping noise when you decelerate.
Loud and sustained or repetitive noise.
Bad head gasket? Cracked Head? CRacked block?
A noise that is 55 decibels loud is considered moderate in volume.
roar really loud noise
Yes, cats' ears are sensitive to loud noise. Loud sounds can startle and stress cats, and prolonged exposure to loud noise can potentially damage their hearing.
