Does the PCV valve need to be removed? Also is this good for fuel injected vehicles?

No to #1,

and, Yes to #2...

Just now installed - Do I cut the white filter off and reinsert the plastic pieces or do I remove all the plastic pieces all together? Looks like no redirect just a hole inside. Guessing that the catch will be there as it is the lowest and the coolest point either way as long as the filter is removed.
** Great idea here - small unit right for my no room engine compartment **
Let me know...

Found answer - the suggestion of 2mm hole in the bottom of the filter makes sense to me to prevent clogging but keep turbulence going. Surprising how tough this little white filter is, I drilled a 1/8" hole in the bottom.

Thank you - hope this posting helps others.
Let the testing begin.

Why silica beads over copper BBs or maybe a Chore Girl copper pot scrubber? I'm looking for the best catalyst to put in my filter bowl. Any thoughts or experiences?

I have one of those on my PVC but the thing is I don't have the filter, just the little catch can or jar that I used. It's worked wonders, I have gotten water/oil from getting into engine and it's not like I have to empty it everyday, it's small and never a lot of fluid in the can.

I've put one of these in the Mazdaspeed and it only has about an ounce of oil in it after 3k miles. And it's turbocharged.
I had one in my Contour and the intake and throttle body stayed MUCH cleaner after installing.
I don't understand why these are not standard on every car.

Probably because you'd have to empty them. People aren't used to removing fluids from their car, only adding or changing. If I understand correctly, the usual design is to burn off all that stuff.

Soooo.....
 

...I think this is a great idea! I stopped by Home Depot but they only had a filter that had a release on the bottom of the reservoir. It was the Husky brand and kind of heavy. I passed on it and am going to check Lowes.

I got home and checked to see if I would need any extra hose and found this:

Im thinking the hose I need to filter is #1 as it contains the pcv filter. If so would making that hose longer cause a reduction in efficiency?

If its NOT #1 which hose is it?
