07 focus sounds like a clanking diesel truck problem with engine? transmission?

What is your question?

From the moment you turn it on my car is roaring.I know that manual transmissions tend to be a bit louder then automatic ones, but mine you can hear a mile away. It sounds like the car is stuck in a constant sate of over acceleration. it also sounds like clanky tin when ever you shift gears(yes the clutch is all the way in). Im not sure if this might be a engine problem or one with my transmission.Not one of my warning light has turned on, so im a a complete loss.
