CCV Mod oil trap

what do you guys think? i put it right in the front of the cab then ran the end of the hose back behind the cab. The inside of it is all gutted out its just a air oil serperatior for a air compressor, so i wouldnt imagine any back pressure increase but someone correct me if im wrong. My question other is how much oil will collect in this thing

looks like a great idea. only time will tell how quickly it fills with oil. many variables involved. keep us posted as to how well it works.

Possible Restriction ?

My main concern is what configuration is going on inside of that lid ? Is it necking down from the pipe size (what is that 3/8") to half or even more than its original size ? If so it could be enough of a restriction to build back pressure in your motor and create all kinds of oil leaks. Everything I have ever read on making these catch cans is to make them large and free flowing. There have been many faulty designed CCV mods that have caused 7.3 owners mightmares !!!

i must agree although it is much easier to just run it out the truck i recirculated mine back to the intake with the hopes that under high load or high boost where the crankcase pressure is highest the turbo inlet side of the intake should help counter any type of restriction in the catch can just an idea but too much pressure in the crankcase will without a doubt cause issues

I too built a catch can and ran it back to the engine. Mine has been on the truck now for over 5 years and I have had zero problems. But in saying that my catch can comes in/out with 3/4" pipe fittings stagered one at the bottom and the other at the top with screen mesh pads in-between. There is little to no restrcition in this type of setup. I have heard of guys just having their hoses get kinked venting to the atmosphere that have caused back-pressure issues and of course oil leaks. I would be really suprised if the above design didnt eventually start an oil leak somewhere...could be wrong ?

What you have may workout just fine. I would watch it closely for awhile because it doesn't take much to create a leak in a 7.3 due to back-pressure.

also something that i have noticed is that most people use a trap design because they want to recirculate it back to the intake to prevent the excess oil buildup in the CAC by catching it in the catch can but if your venting it to atmosphere it dosent matter as long as you keep the end of the hose clean from debris and dirt that would limit flow of the gasses coming out unless your a environment concious guy which would negate you even being on a site like this lol but who knows
