Hey guys, I thought I'd make a short write up on my install of my catch can I needed on my 6.0 to stop the smoke under boost.
A little background, I put an ON3 7665 in front of my Gen III LQ4 hoping to brake the 500 hp mark at the wheels. At first I grabbed a cheap, $30, ebay catch can and plumbed it in. All I noticed was vapor blowing right through it and out the breather, the can never accumulated 1 drop of oil. I don't want any smoke under boost so I splurged and order the Mighty Mouse PCV can. I was very impressed. I recieved the can in under a week, pretty sweet since i live in Montana and away from every manufacturer. Fit and finish is excellent.
Here is a few pics of the install:
At first I had to pull my old pcv system and trash the ebay can.

I am using an early 04 Lq4 which has one port on each valve cover. It is also important to note that I do not have an LS6 valley cover.
I installed a short pod breather filter on the back of the driverside valve cover for my fresh air into the system. You can do it this way or run a line from the intake side of your air filter.
I pulled the passenger side valve cover off and used a long screwdriver to rotate the outlet 180 degrees so it points straight back instead of forward. This way I don't have to make a 180 with my hose to head back to the can that I mounted on the firewall.
Next step was to find a place to mount the can. MightyMouse lets you select which type you want to use for a mount, I elected the universal mount because I didn't think i would have room on the head. I mounted mine to the firewall behind the passenger side head.
Next step is to run a hose from the port that we rotated on the passenger side valve cover to the black, or dirty side of the catch can. Then run a line from the silver clean side to an available port on the intake manifold after the throttle blade.
Fits good, looks good.
The install took less than 30 minutes. I am excite to see how it does, my goal was to not have any smoke under boost and seeing that my motor has 132k miles on the clock, it is a sure bet there will be some blow-by when we pressurize up the system. A little more tuning tomorrow and she will be ready for the dyno on Tuesday to see what kind of numbers it will make on low, low boost. <br/>
so how are you getting clean air into the value covers? What I did was get a one way check value and ran it to the turbo or intake pipe before the throttle body so you can get some clean air in the crack case and under boost the one way check value closes it off so dirty air cant get pushed out.
so how are you getting clean air into the value covers?
breather on the back of the drivers side valve cover or you can run a feed line from the intake of the turbo. before the compressor/after the air filter.
