Engine clicking on Mercedes C230 Kompresor 2005


i had the car for 2 years and never had any problems with it.. now i have this clicking noise comming from the engine, i recently did an Oil Change with Mobile 1 full synthetic as always but the clicking is still there. and i noticed that the horse power has gone down drastically, i would probably say that 35% of power is gone..
the car has 85000 miles and i did not change the spark plugs ever.
could that be a problem or maybe is the air flow sens, let me just mention that i don't have the check engine light on.
Thank you all.

I had the same problem...took it in for service and it turns out my water pump was faulty. In fact it had blown. The clicking was the valve running metal to metal.
