A couple things if I will...

1) Care to tell me how a boost gauge will aid in telling if there is a valvetrain issue?

2) A Boost gauge won't tell if there is a misfire...only thing is will tell you is if you have a vacuum leak or not...

3) If you let a noise like that come and go and not even attempt to fix it...you shouldn't be around cars.

4) Try using F7. It is a WONDERFUL thing. My head hurts after reading that.
