with twin cam 16 valve written in red. I compared it to my ze rocker
cover and the outlet is much smaller. Also, looking at the underside
of the covers I saw the ze one is much simpler in terms of plates/baffling
than the other cover. The differnce in design isnt gonna be a problem
would it?
Oh and how hard is it to modify the rocker covers to have additional
outlets?
not to hard, drill a hole in each and weld in some alloy tube, from memory last time i used 3/4 tube and hose.
A lot of the expensive japanese ones dont either, for the reasons i explained above, This kind of catch can is not supposed to have a breather on it as it contravenes emmissions regulations. These sealed types are designed to be put inline as a condenser. A catch can with atmospheric breather filter is of course not supposed to be an inline device. I actually run 1 of each kind in the caldina - that way you retain the benefit of the PCV system as well as preventing any oily vapour entering your intake system.
if it does not have a breather and its not plumbed back to the intake it wont do anything, it has to be able to breathe and vent crankcase pressure.
