JTS doing random noise (video)

this morning i noticed a strange knocking noise coming apparently coming from inside of the engine. This noise has increasing while i was trying to figure out from where it was coming. The video shows the current noise.

as you can see in the video after sometime it stops so it is currently happening at random but i guess it will get worst.

my real problem is that i dont have a clue from where to start. Any suggestions are welcomed.

so far i have checked engine oil. still enough full, and it has the proper selenia racing in it.
there are no things rattling with the engine. just checked
I have oped the top cover cap and i could see oil splashing so im guessing oil is pumping up.

tomorrow i was going to open the rocker cover to check for any possible traces to what could be the cause.

Thanks

Could be a bad oil filter, I had one that produced a sound similar to yours. It only occured during idle when the oil pressure was at its lowest.

If it is not the oil filter, it doesn't really hurt to try atleast.

My engine was the 2.2 JTS and i found the fault by browsing topics in other forums related to the GM 2.2 Ecotec engine which the 2.2 JTS is based on.

@ Balthazar, the engine showed is the Fiat/Alfa engine this one has nothing to do with the 2.2 Opel engine. Not that it is a better one .
@doutlaw, it sounds like a shroud thikking against the outlet; Otherwise the camvariator, if that one makes noise the noise often disapeares when the oil gets hotter.
