Has anybody tried doing this? I think this will be equivalent to installing a breather filter and attach it to that PCV valve(?). Because I'm really sick of seeing oil seepage on the tube coming from the valve cover into the air intake, going to the turbo(isuzu 4jb1t)...there really is not much oil there but its enough to get the joints wet I've read about this on the other threads but really haven't seen anyone who actually tried it...any pros or cons on doing this? thanks guys!
