Catch can help needed
I have an A&A kit w/meth on my 2014 Z51. I bought a Colorado Speed Premium catch can (dual port, so 3 topside connections) for it, after I saw the oil in my intake. Problem is, I'm too stupid to figure out how to install it. I'm no mechanic, but I know one end of a wrench from another. The instructions aren't for a blown car. I found a post for installing them without drilling the intake tube, which sounds great...but that just seemed to confuse me more. My vacuum line has been spliced for the meth pump, so maybe that's why I can't figure it out. Any "catch can for blown car for dummies" help is appreciated.

OP here really call the speed shop that made the can for the correct install info here. Most cans are diff from other can set up one can hook up is not the same for every can with a blown on it. What I mean by that is one can may be made with a check valve in the rubber line with under boost in closes, then a diff can may have the check valve in the small air cleaner & it needs to be hooked up diff.
But most one line to the intake, one to the valve cover on the drivers side, then one to the oil tank that you put the oil into the car on the z51 but then you also need to block off the one line also on the oil can also..
I will tell you this if you do it wrong for that can set up you can do more harm than good on it..SO CALL THE VENDOR OR THE MAKER OF YOUR CAN.... Robert

Robert is dead on. If you want one that works with NO FUMES go with the MILD setup by MMS, it uses a billet PCV diverter and PCV valve to control fumes at idle/cruise yet open up on boost. Worked like a charm on my 1000 horse procharged build, but I added an AMP to mine to help my road race application. The MMS is more than enough as MILD for nearly all Z's. Most don't realize that.
