i'm lost! vacuum leak?
 

i have speed inc valve covers. they are set up for a breather on both sides. i have PCV on my car so, what i did is plugged up the both filler necks.

now it seams that the car doesnt "cam" as hard, and the motor doesnt shake as it used to with stock valve covers and my cam.


do i have a vaccum leak somewhere? would a vaccum leak cause the cammed motor to run smoother?

i'm lost. the idle sound changed noticably, the car doesnt "stumble" as much
