Boy, it sure seems a lot of work to capitalize every word...

It is an odd answer, but I think one or more of your intake valve are not sealing. Engines make a horrific amount of noise if you pull one spark plug, then start it with the other plugs still in.

There just is nothing in the intake system that can make noise, except what is on the other side of the intake valves.

Do a compression check. If the intake valves are having a sealing problem, the compression will be low.

If the cam that opens the intake valves is late, you could get a short backward flow just before the valve shuts, which could make some noise.

This is a truly odd complaint you have. But that;s all I can think of that could do this.

Timing belt broke on hyundai sonata 2002 what should I do? The mechanic saya theres a ten percent chance that replacing the belt will solve the problem.

You can have your mechanic pull the valve cover. Loosen the bolts that hold the cam(s) in place and do a compression test. If one or more cylinders is low on compression the motor is junk. If the compression test is fine reinstall the cam and replace the timing belt and you should be good to go.

My mum had her hyundai sonata timing belt replaced yesterday and was on her way home (100km) from hyundai shop when the battery light flashed and steering became difficult. she pulled over on the side of...

Most of the time accessory belts are changed along with timing components. If the belt was bad already they should have changed it or called her to say it was bad. I'd think this one should be on the house - either they reinstalled a bad belt or improperly installed a good one.
