What would be the disadvantages of changing both valve cover breathers to small K@N filters?
I have the passenger side plugged on the TB right now so I don't lose boost, but that creates a vacuum leak only having the drivers side hooked up to the intake.(through the pass side valve cover, through the crankcase, and out the drivers side cover into the manifold unmeasured)
I did have a checkvalve on the pass side but this created extreme vacuum in the crankcase.
Will doing breathers on both sides cause any problems that I'm not aware of?

thanks, Rob
