I had planned on draining it at each oil change but I only have 4200 miles on the oil (and 3 1/2 months). I live about 80 miles east of Chicago so we're in winter weather. The picture shows the amount drained. Gurgling stopped.
    What is that mess? Oil and water?

    Have a look at my post when I installed mine. This may be good enough to get you there. First, check the hoses are on the correct ports of the can. http://www.cadillacforums.com/forums...tion-pics.html

    Which hose goes to which valve? I remember installing via the instructions; I just want to verify.

    Re: Rx Catch Can "Gurgle"

    The center of the can always attaches to the crankcase "dirty side". Generally a barb on one of the valve covers that goes stock to the intake manifold (NOT the intake air tube (CAI). Then the outer valve runs to the intake manifold for vacuum (where the stock line did run). Any on the cleanside, (the air box or intake tube) is not used except on a forced induction application.

    In the winter months, the cans will also trap a ton of water vapor as well so need to be emptied at shorter intervals than in the summer.

    That's how it's hooked up... I've opened it up to drain again since my first post, nothing comes out...

    If you have it hooked up correctly then what could it be? I can only think of something being wrong with the can itself.

    Maybe so, I never heard it before as it was attached to the engine cover stud. Over the Christmas break I moved it and attached it to a spot on the firewall... It's probably been making the noise all along, I just could hear it before. However, it's never had anything that's drained out if it at either location...

    The can valve will always make a slight "buzz", but this is the drain closed...threads extended:


    This is the drain open, threads retracted:


    To check if the drain is open you can try and blow through the drain tube. If the drain is stuck you can remove it with a 9/16" wrench and it will drain and if thats the case let us know so we can send a replacement.

    That's it! I took the drain off and all kinds of crud starting running out! Yay!

    So, send me your email and I'll give you my address; I've moved since you shipped me this one.

    Re: Rx Catch Can "Gurgle"

    Yeah, I hope this is the answer to your issue. I just checked my can 3 weeks after installation and I wanted to make sure it was working. The valve really works hard (had to get a torque amplifier on it) but once open I got about a half to one cup of liquid out of it. Looked like mostly water as it was not real milky or overly oily. Good luck with getting it working well.
