    I can't smell mine, but I have to passenger covers that have oil filler breathers.

    i also dont have any baffles cuz i cur them out for my roller rockers.i wonder if this has any bearing on it.i actually get alittle like idk if its smoke or condensation coming out of them but i see it and smell it.it makes my feel like im driving a pos.when i come up to red light or stop.i dont think its anything new because its done it since i installed the breathers.i wonder if a catch can setup would help.

    I don't have FI so I don't have any real life experience with that subject. I have a breather on the driver side and I still pull vacuum from the driver side and the valley cover using an LS6 cover plate.

    LS6 valley cover will most likely solve your problem.

    I put a catch can inline and ran the factory system. I couldn't stand the oil smell.

    I have the same symptoms as you. I've been told that it's normal for a breather setup. I think I'm going to go back to a closed system as well...when I come to a stop I get crankcase fumes blown into the cab through the a/c. Anyone wanna get high?
