I have ran two breathers with no issues, but noticed that my oil gets black real quick.
Not trying to hi-jack this thread I just have the same dilema.[/QUOTE]
With two breathers and no PCV valve, all of the carbon from the blowby gasses stay in the crankcase and turn your oil black and is corosive also . Not a good idea. Install a PCV system to make your engine last longer and run cleaner .
