hmm... ive traced an annoying noise to my valve cover breather on the passenger side... it makes like a tapping noise kinda.. and if i manipulate the line coming out of the valve cover that goes to the intake manifold the noise changes.. i took it off with the engine off and couldnt see anything out of the ordinary... i really am stumped on this one, any ideas would be supremely awesome!

I believe that is your PCV Valve which is supposed to rattle if taken out and is part of your emission control vaccum system. The rattle lets you know it's still good. And the line noise you hear says you need a new vaccum line there. Don't go the cheap route here. Get the right kind of tubing.

When you take it out, it should rattle if you shake it. The more it rattles the better it is. Spray it out with carb cleaner real good to clean it, or you can get a new one for like $3. I would clean or replace it and if it's still real loud when running, inspect the line going from the PCV to the intake. Like Russell said there may be a small leak in the hose.
