Now that I've essentially got my junk figured out, i want to look at adding a PCV in the valve cover since my intake doesn't have provisions for one. I know about using 2 check valves, i know you recommend the turbo coupe pcv. Is there another option for a pcv? I really dislike the double vacuum ports on the stock motorcraft unit. I hate having to use vacuum plugs that dry rot, leak and fail over time. Would say a pcv from a 5.4 f150 be acceptable? My car only pulls 10 inches of vacuum because of my altitude and my cam so i have to be careful, i can't afford to lose much more so that also needs to be taken into account.

you can use any when you put a check valve on it

Are there any that flow less or more? I dont want to install it an lose 3 inches of vacuum.

if you loose vac with a pcv setup then you have a leak
