LB7 PCV re-route??

[kubitza123]

Deleting my Cali LB7 . The routing has got to be changed to work with my new air cleaner / y-bridge etc. Does anyone make a good kit to fit valve cover ports and where I can route it to a catch can or??

If anyone has done such and has some input let me know please .

Ran mine with 3/4 hose to that catch can off the drivers side valve cover. I had to re do mine when I changed the mouth piece on the turbo. The pcv was tied to that an I didn't want it venting to atmosphere, but if you dnt care throw a piece a 3/4 hose off it an let run it down the frame rail. Make sure not to kink the hose when running it.

I got the DRP billet plugs and used 5/8 from each valve cover. Both routed down passenger side frame using DHDs method for under hood routing. Driver side hose loops over turbo mouthpiece in front of firewall and drops down near fuel filter

Well the Cali emissions run a steel line over the top of the intake to a port on each valve cover , which meet and run down to the front left of the engine . I'm going to cap off the port at the front left of the motor since the engine vents will no longer be going to it.

I was hoping there is a nice fitting setup or kit to run hose front each valve cover into a catch can . If not I can run hose down on each side or tee them together and run one down.

I'm fully deleting all CALI crap and fuel filter since I'm adding a Fass 150.

Most peeps don't run a can, no need unless you just feel like it or want to offset our environmental abuse. CCV is different than PCV in that you don't need to complete a vacuum loop.

I don't have to have a catch can but without one have you had any issues with it running oil down under the truck?

 

[oscyjack]

Unless you have ungodly amounts of blow by you won't see any oil.

Now and then depending on atmospheric conditions you can see the gasses exiting the hose when the truck is running , but I've never seen a drip.

I just ran the drivers side under the intake horn in the valley and up to a tee by the passenger side and to the original vent location. No need to go crazy with it

Yeah pretty simple. I personally didn't want to use a t. It's about he simplest "mod" you can do.

Why modify the factory setup? It is just a vent at the front of the engine with oil recovery. I've run the factory setup on all my LB7s for almost a decade now and never had a problem.

Is yours making a mess, or smell bad, or something? Because what you are describing can be achieved by just putting some hose on the end of the factory vent and routing it wherever you want.

No mess, just with my new intake horn and Y-bridge the steel line etc that was there before won't work now. I'll run them together and down the back of the engine etc. Just wanted to be sure there wasn't a reason why I couldn't .

Little extra work but tied mine into exhaust system.

x2. the acc bracket its built into is its own catch can with drain back feature.

OP, i would just make some new hose and reroute it to the bracket. did that with mine when i put twins on, then redid it when i put LLY heads on.
