For anyone that doesn't know even a perfectly running engine will get some oil that travels up the vent tube from the valve cover to the intake. That oil burns off in the combustion chamber usually and also coats the inside of the intake over time, reduces fuel economy. On a power adder engine it's a big issue because that oil getting into the intake mixes with fuel and essentially reduces the octane level of the fuel you are using and can cause detonation.
As for being necessary that is up to you. I've seen forced induction engines detonate due to the oil in there. I've also worked on enough engines to see how nasty the inside of the intake gets with that oil making it's way in there or even gumming up the injectors. Granted that's over time but I'd rather have it on there and prevent some of that mess if possible even though I don't plan on doing anything to this engine.

I also think a lot of these applications have been developed for the race industry such as CAI, catch cans, tunes and such, and people had the brilliant idea of pushing it on the consumer market. A lot of it is theory and there is some research proving some of it. I just dont think a lot of fits an every day application. A lot of these bolt on features are used in racing where they were fit with different headers, cams and such. So all of this stuff belonged in an over all package. I think companies have taken some of the easiest produced parts and marketed them to us. I mean look at intakes, a $5 peice of plastic and $10 peice of steel is marked up to 300 bucks plus.

For me proof of the product is right in "CaperJs" thread # 15 . Do you really want that gunk on top of your plugs and pistons cause thats where it ends up. I have used a catch can on a stock 4.6 set up and recovered just as much oil as shown in that picture. Do not think that this is just for modified cars. Nards how can you say its a hoax if you have no experience with one?
Before my new set up with breathers i have used one on a 4.6 for about 28,000 miles from stock to 562 RWHP. Would dump about 2 ounces of waste oil from it every 500 miles or so.

I had one on my VW 2.0t be cause it was direct injection and had problems with cardon build on in the intake valves. That one caught a ton of stuff. If the 5.0 was direct injection i would get one, but i dont really see the point on just a street truck. Its just another maintence item that you need to check. If your that worried sea foam it every couple oil changes. Im sure that will take care of most of the oil build up on your intake manifold.

Considering getting one of these. looked at the UPR and the JLT.
My main question is what causes the the blow off oil to just be transferred into the can, then just be blown right out the opposite end?
Is it the weight of the oil entering that causes it to settle?
I see no mention of a filter in these.
So, what's stopping the oil, and for it to collect in the can?

I highly recommend all you 5.0 guys take a few min to do a search over on svtperformance in the mustang section. I know when i had my 2012 gt i was on there every day and it was a huge deal how much oil ended up in the intake during normal driving.

Just bought a JLT one today as I spent a few hours reading about them and they sound like a good investment and they actually work as a lot of guys are running them on their 5.0's and swear that they work and actually have pictures proving that they are catching oil in them! I went with the JLT one as it is plug and play using factory hoses and connectors so it swaps out with the factory hose in a few minutes in case you ever want to remove it. The UPR can and the few other kits on the market don't have factory connectors and the hoses on some of them don't stand up to the vacuum pressure so you are having to spend money on additional parts! JLT seems to be a very reputable company within the Mustang community and their customer service is very good so that is why I chose them.
