Alright so i recently installed cams....i know what most of you are pry thinking right now to....BUT! i'm getting this rattle/ chatter noise and it seems to be coming from my intake manifold for some reason...i did have some lifter tick and i just popped the valve cover and checked all the lifters to make sure they were all fully pressurized but i did find one that wasn't completely pumped up so i bled that and the lifter tick went away but thats besides the point...

what would cause a rattle/ chatter noise from the intake manifold it sounds like metal chattering or something loose and it isn't a consistent noise it comes and goes sometimes when i drive the car it doesn't make the noise at all but sometimes it will do it alot but not the whole time while driving the car...

thanks in advance for the help!
