My car started making a Lund noise from the engine while ...

Hello, Welcome to Just Answer My name is \*\*\*\*\* \*\*\*\*\* I've been an automotive engineer since 1996 and together we're going to solve this issue. 1st stop the engine and then check all the fluid levels ( oil, coolant, transmission) are correct then take a look at the belt drive of the engine for anything amiss here, loose wobbling pulleys etc then check the state of the exhaust pipe I'd start by checking all the exhaust joints - where the manifold joins the head and the down pipe joints just before the catalyst - the best way to do this is to start the engine from cold and feel around each joint with your bare hands - feeling for exhaust gas blowing over your fingers - you'll have about 30 seconds before it all gets too hot. also look around the pipes and on the body for signs of soot - another indication the exhaust gas is leaking out

Well my car is leaking something from the front passenger side also I have to take it to mechanic to find out tomorrow

OK before driving it just check the fluid levels as you don't want to drive it with low oil or coolant as you may damage it
