This is driving me nuts

[Emode]

im telling you guys its ok
i was freaked out for awhile, it comes from that lttle area on the bend right before the TB, the little plastic thing that sticks up and has a line or two running to it
its a pressure valve that opens on and off when the engine is idling
turboge gave a big explaination in another thread awhile back
it is normal, and it becomes louder when you have a boost controller in too

Ok if you do not have turbo what is this tapping noise.

The tapping sound is very speratic, its not all the time but it does happin when there is a load on the engine it seems.
I am going to upgrade my gas to the higest oct to see if it goes away, almost sounds like bad gas no?
