I have a 1993 Honda Civic HB 1.5L DX. I have noticed recently that there is a loud noise coming from the engine area. it sounds like an ai hose.. it only makes the noise from 4-7 thousand rpm. and is very bad during 2nd gear. I am also losing coolant. do you think they have something in common and if so what do you think it is?

 

Pop the hood and rev the engine by hand to see where the noise is coming from.

 

the engine only makes the noise when i am driving. i also have to be driving long enough for the car to warm up. i am totaly stumped
