Engine noise

Hey guys, my car has been making this tap tap tap tap noise when the car is running, usually louder when hotter. I found a video on youtube where the engine is making exactly the same noise. Any ideas what this might be.

Thank you

Actually i decided to go to the car and diagnose the noise myself. Removed the engine plastic covers and at this point noise was even louder. I took my stethoscope and started to listen onto everything. I heard the noise the loudest on the ignition coil of cylinder n4. I removed the coil and I could smell exhaust gasses on the coil boot which I though was not normal. I checked the spark plug and it was not tight at all. Removed it to make sure it was ok and then tightened it back. NO MORE NOISE!!. This stupid noise had been around for a really long time and was getting progressively louder, I just never took the 15 minutes to investigate. Now the engine puurrrssss the way it should. So for those that have a noise like the one in the youtube video i posted, CHECK YOUR PLUGS!!

Thanks
