I’m blowing lots of smoke from exhaust after installing the RacerX intake manifold and 42# injectors. Just don’t know what to do or why this is happening. Any advice would be great. Thanks

Did you program your ecu for the changes?

I had a tune done for the injectors. My tuner said I didn’t need one for the manifold

Yah that's correct from what I understand. Well white smoke usually means coolant burning, steam due to condensation on cold starts, and in some cases light oil burning. Check your coolant level after the engine cools for loss, also look into your pcv valve. See if the little port under the ignition coil cover on your valve cover is sucking air at idle.

Coolant level is good. I only see smoke when I go past 5000 6000 RPM

Probably your pcv. Definitely suspect since you changed your intake. Pull your cold air intake from your turbo and see if there is oil build up at the pcv return from the hose that comes from the valve cover. Also pull your plugs and see if they are wet or brown. Probably just burning oil vapor. Does it idle ok?

There was a ton of oil in there and I pulled the intake again and it was everywhere and in the throttle body. Honestly I think I’m just gonna port the OEM intake and put that back on with the Cruze kit. It idles fine though

There's your problem bud. Pcv issue. How much was that racer x manifold these days? I want one.

Well what would I have to replace? I got the new pcv system with the manifold. It’s all brand new. I was thinking maybe I put the valve the wrong way on the pcv lines. I have the arrow pointing from the manifold to the turbo.

Yah that's correct I think. Could be the valve cover one way valve. Did you get the kit and block the port with the acrylic and stopper? Maybe that failed? Should be able to look down it with a flash light.

The racerx manifold is completely different than the stock one. It doesn’t have that port to block

Oh right, Duh, my bad. I think there is a badass diagram of the pcv system online. I'll see if I can find it and link it.

And here. This one is a little more thorough....
