    Maggie owners check for this

    I mentioned this in another thread.

    Remove the vacuum line to the brake booster (maggie end) and swab the hose for oil and the barb fitting.

    If you get oil you need a catch can.

    Mine was full to the top of the fitting and there was a pool inside the maggie.

    One catch can (I have duals) was oiled up and runs to the same vacuum fitting (the other side) as the booster.

    The other catch was connected to a fitting on the maggie further upstream and I guess has less vacuum as it wasn't oiled up.

    So.....

    I am gonna connect one catch can (a bigger one) with dual fittings and see which vacuum fitting works the best.

    Also, upgrading all the 3/8" vacuum line to silicone.

    Got it here: http://boostcontroller.com/

    MOD HELL

    Any chance you can snap some pics of the lines you routed to the catch cans. I'm still baffled by which lines to catch oil from and having the ls2 doesn't help as no one seems to have done it.

    I think the LS2 has a built in breather near the back of the motor and is part of the valley cover.

    That's where most trucks put them........

    Should be duck soup to grab that line and add a catch can to it.

    The LS6 has one each on the valve cover.

    It ends when you sell it or wreck it or it gets stolen, although it might get recovered (Murphy's law).

    I gave up model airplanes for this.

    The MSD coils are gone as I just had too many failures.

    I installed this "catch-can" yesterday on my LS2.

    Why does this look different on my maggie then. Only have the two hoses going into the maggie on driver side. I'm assuming the top one needs to be tapped for oil.

    Catch can is also on the passenger side Hopefully length of hosing won't cause issues.

    Here's the image.



    Actually just made sense of the earlier pic. Bottom hose out of the two that are on top of each other would be the candidate.

    Is that some sort of a pressure gauge or check valve I see on the catch can?

    Re: Maggie owners check for this

    Looking at those pictures. I would say you have it installed incorrectly. The line has no restriction in it so it would technically be a vacume leak at that point. You should run a PVC valve or equivalent in that line going to that port. That would be why you are getting alot of oil. It is just sucking it right out off the rocker assembly inside that valve cover.

    I usually run BOTH top ports to one single line, then put a PVC valve inline on the single line and install it on the large vacume port you are using. That way it is regulated and not such a large leak, then at wot, it will open the pvc valve and allow blow by to leave the crank case as designed..

    My pic? Or the oil catch can pic from the other guy?

    And yes I think a check valve is in order with or without a catch can. Any recommendations on check valves and places to get them from?
