Catch Can Questions I need a vented catch can, but not sure which one I need. I need to connect the vent hose coming off the passenger side valve cover to a catch can. My TB does not have the vent tube, which is why this is needed. Which catch can do I need?

I'll likely purchase a Mighty Mouse one. He has three different kinds. I know I need a vented one because I need fresh air going to the crank-case from the vent tube coming off the valve cover.
Your TB doesn't have the tube?
I posted a pic in your other thread. So not what you need. I have a Mike Norris catch can. It's a good one for the price. But the Might Mouse one looks excellent.

Nathan,
There are a few options for you. You could just put a small breather filter in place of that hose, add a fitting to your intake tube between the throttle body and air filter or route it to a catch can that has a filter on it.
Yes, that line coming from the passenger side valve cover would normally connect to the vent tube that comes off the TB. My TB has no vent tube. Jason at WARR Performance I had three options, one of which is running a catch can with a filter. Just putting a breather filter in place of the hose sounds easiest, but no clue where I would get one:

Here is before and after. Before having a breather on the oil cap and passenger side VC vent blocked off.<br/>After: Hooked up PCV properly along with a catch can.

That's pretty crazy power difference. I am no longer running a pcv setup. I have tried 1 can, 2 cans, multiple routings, multiple pcv valves, multiple valley covers, all hooked up with a vented can, breathers on both covers, breather on 1 cover and all have yeilded oil coated intakes on a stock 5.7, heads / cam 5.7, and new 408.
I am now running both valve covers and valley cover to a vented catch can and blocking all tb ports. It will be interesting to see what the dyno says, but results will be off due to also upgrading heads...
Pcv and catch can setups sem to work different with all motors for some reason. Some suck no oil through, some like mine are always coated no matter what way you try.
