Could you please throw some light on this problem.
When car is first started, a rattling noise seems to be coming from the air filter after about 5 mins the engine is perfectly quiet.
I await your response.
Thanks

noises ono here are hard to diagnose simply because it's a lot easier to hear it and give an opinio. but i'd pull the air cleaner apart and see if the filter is loose or a foreign object is inside it. It could also be a piston noise that when it warms up it goes away and what that is commonly called is piston knock or slap, so when the piston expands it goes away..it doesn't hurt anything.
