Everytime I go any faster than 60ks my car starts to make this weird sound..its hard to describe sorta like air or something is going into the engine? i dunno..but it does not effect the power and idols fine and doesnt make the sound in reverse or going slower than 60, and its pretty loud..any ideas?

car's not over heating and the coolant not boiling and causing a thump when the air bubble burst inside the block.

have a good look in your bay, sounds like you picked up some debrit and is making the noise as air passes it
