2019 6.2L UPR Catch Can with CSS

[clowe1243]

So I bought the CSS kit for my 6.2L and it just doesnt seem right to block off a valve cover.  Do you guys see any issues with this setup?  I thought the valves need equal pressure.  UPR said the catch can equalizes it.

Thanks for the diagram I am in the middle of installing mine (have it plumbed but not hooked up).  Wanted to confirm the cap off.  

 

What CAI are you running?

Sorry but all wrong.

Passenger to driver port then out css to can then valley to can then exit on can to manifold port. Unless the can can't support that.

 

This gives you two in ports to can and one vaccum line. Vaccum line to manifold. This way every line goes to can.

There are three ports on the can.

According to UPR and a couple race shops, it just mean the gas will go out the driver side instead both side.  It's still weird to me.

They are wrong. Best to atmosphere breather is force induction however on natural aspirated we have seen blown rear main seals with high oil and pressure. So if gm gave you a port use it.

I'd hate to ask, but can you send me a drawing of what your suggesting?

This is my first set up but you can see the jumper hose over manifold then CSS to the can. Then other can port is dirt valley. Then vacuum for me is pre turbo.

There is no dirty side valley on my 6.2.

I have two valve cover outlets, manifold inlet, the oil fill, and the CAI inlet.

No wrong. You have one. See pic
