Like the title states, I got my new radiator and I am in the process of mounting it vertical. Well I started removing my upper I/C piping and noticed something kind of orange in look in the pipe and my new TB. Now this is a new...forged LS3 with FAST TB and the radiator is filled with Prestone coolant...Green. My TC78 is a journal bearing only turbo...no coolant lines. I also pulled the filter and checked the compressor and it looked clean...minimal shaft play as well. What the hell is this stuff? It's not oil....wipes off and doesn't smear. I have lines hooked up to the intake pipe of the turbo for my PCV setup.

Rust? That's the only thing that i could think of. maybe from condensation? is your cold side aluminum?

My cold side is aluminum.

Condensation from the iron block circulating from the PCV system? I'm completely shooting from the hip here.

Sweet_SS

**** maybe. But how...why would it go through the turbo?

sorry, i take that back. I re-read your first post and saw that it's an LS3 block. I'm stumped.

Sweet_SS

Your right lol It's an LQ4 block with L92 heads and LS3 forged internals.

ahh ok. i would pull a hose off of your PCV system and see if it has the same orange residue.

Sweet_SS

Sounds like a good idea. Thanks for the input

Its rust .water. Mine does the same if it sits around and forms condensation.

Cool. I thought it might be from when my LS1 blew. I'm pulling the intercooler and power washing it. Couldn't hurt to clean it up some. Thanks Sprayed01.
