DIY CCV mod

[colinmitchell111]

I know some on here have done this. I plan on dumping it under the bed somewhere. What size hose do I need? I should use heater hose I assume? Does it just attach to the valve cover with a hose clamp? And what is the best way to plug the intake boot hole? Thanks.

I had a lightweight aluminum plug custom machined to go in the intake tube. I also used an OEM style crimp clamp to secure it. I used 1" Gates heater hose and connected it to the factory elbow on the valve cover. I ran the hose up around the brake lines and down to the bell housing. Then I reused the 90 elbow that used to go into the intake and made a 90 turn straight down with another section of 1" hose.

After 4000 miles I still have zero oil dripping from this hose and very little blowby smoke. Just a wisp if you hold the flash light just right at night. I tried to source some nice 1" oil rated hose but I didn't find what I wanted. Heater hose will last several years and is easy to get. So thats what I used. I've had heater hose on a Cummins ISC blowby pipe for 10 years now and its dripping with oil. Its still solid and hasn't broke down.

No way would I run the hose back to the bed. Just drop it behind the engine. Early Duramax and Earlier Cummins engines put the outlets directly in front which can cause dirt to stick to the engine over time if the oily residue is never washed off.

Putting rearward of the engine and hanging down a little keeps things clear.

Here is what I made...aluminum machined to snugly fit inside the rubber hole of the plastic tube. It has a ridge so it can NEVER be pulled into the intake. And its been cored out so the wall thickness is 0.25". This helps make the piece very light. Its flush with the inside of the intake tube once installed.

Wow that plug is nice. I'm not really concerened about weight or looks though. I was thinking a bolt would work, that way the head would keep it from sucking through. Any ideas on what size that way I could get one before I start?

OK I want one. How much do all of use have to pay you to convince you to start making them by the crate full!!!

2x on the plug. I used clear 1 inch tube about 8 feet long tied to the frame rail.
