Default Oil in the air box

I am just starting to reassemble all the parts to reinstall my new turbo.
The air box had quite a bit of oil sludge built up in the bottom, and a bit damp around the throttle body when I disassembled it. I have cleaned it up as best I can, but I am wondering if it's the PCV valve not working. The small sponge where the PVC hose enters the box was saturated, and I have replaced that.
Can anyone give me an idea what would cause it if it's not the PCV valve?
Thanks for any suggestions.

You can Put a breather from the oil line that goes from the head to the airbox, where is a sponge that catch all the oil... just run a hose from the head and then at the other end put a oil breather its like K&N cone filter but really rally small!, and put it in a high position so the engine can breath and the exes oil returns to the head with no need for a catch can

Tomorrow I post some pics, heres is night and can capture a thing LOL

You'll see my breather just near the top between the cold up-pipe and intake.

Oh... ups, that one lol... Man I see that you have a HKS Bov? is that better that the one in our chargers?, I tough that it was better because it was located more close to the turbo... how does it work? its just for the sound? or do you see any better performance?

Daniel

PS.. I copied you

The 'stock' valve that's on our turbo is a recirculating valve.

A true aftermarket BOV (such as my HKS) releases the excess pressure that sits in your pipes when you close your throttle body. Since the pressure has nowhere to go once your TB is closed, it'll normally go back through your pipes/intercooler making it's way to your turbo. This spins your turbo backwards which causes even more wear and tear and can cause a bit of turbo lag since you'll have to get the turbo spinning forward again once you hit the gas to create boost.

It's not so much a performance thing really, but I am one to believe that it can help your turbo in the long run. Plus, it's just one of my supporting mods. I plan on going with a bigger turbo, most likely something from FM such as the E1. Rest of my current mods are in my sig.

Yeah... nice... I think anything to prolong the turbo life its great!... BTW I ordered a Mopar blue plate (replica of course on ebay for 20 bucks) will that help the same way? because it going to vent to the atmospher... know its a little to noisy... but dont care, I hope do his job, because I removed the silenser, and now I have the hard pipe, and can hear the flutering? or how its call? that the impeller its been hit by the recirculatyng air

If it doesent help my turbo whell Im going order a block off plate and go for a BOV but... the unfamous blue plate helps?

Thanks....Daniel

HKS is a good bov, but you don't need a real bov unless you are running over 20 psi. After 20 psi the stock surge valve can leak.

Not entirely true.

I'm going with a bigger turbo later in the future, but my reason for going with a true BOV is because my stock recirculating valve was leaking (diaphragm went bad). Instead of replacing it, I figured it'd be my chance to upgrade now to a true BOV. At 8+years old, who'd expect that cheap piece of rubber to last anyway?
