Pooling Oil.....

[SHOTM]

2011 Heavily modded with with moderate miles lol...been noticing oil and residue on my charge pipes couplings for awhile now but only after I replaced front turbo's Hot pipe and a split OEM intake pipe assembly I noticed excessive pooling in the coupling from the back turbo....as pictured
No power loss whatsoever, actually runs better than ever with the boost leak fixed which was the initial reason for inspection/replacement....I guess my question for the community is.......is my turbiskis finally shot ??? Even with all the new felt power or is it a gasket/seal issue? Any input I value .... thanks.

Got a catch can setup?

with that much oil i think its at least worth a look at the turbo, and like @kryptto said do you have a catch can? I'd imagine if the only symptom is oil pooling and theres no loss of power or obvious noise maybe the turbo just needs a seal, more experienced minds may have some better input as to if the PCV system could cause that much pooling at that spot

I replaced both turbos with new OEM and still get some pooling. I have a Bank 1 PCV catch can but that's only active under no boost conditions and even without it, any oil coming through the Bank 1 PCV port gets burned in the engine. For under boost crank case pressure, I vent through a modified oil cap and the OEM line connected to the intake pipe. I did this because the OEM Bank 2 PCV connector is metered and I measured 2-3 psi of crankcase pressure under boost (look inside the PCV connector on Bank 2 and you'll see it has a tiny hole in it...it's metered and thus, builds pressure). My modified oil cap vent doesn't allow any crankcase pressure to build under boost and it terminates to one of those glass fuel filters with the filter removed (see below). It operates as a catch can and it has a very, very small amount of oil in it. I don't know where my pooled oil is coming from and it may be that the turbos just naturally are weeping some oil. But I have another turbo car running a T3/T4 Garrett and it's bone dry, so I'm not certain.

Normal.

Got a catch can setup?

JLT 3.0 yes....catches a little but not really enough in my opinion, when I go to dump it

The only thing I've done on the PCV system was replace the brown PCV valve on the rear valve cover ....im with you on this one now that I'm reading about a seal....thanks my friend.

I'm thinking if you replaced with new OEM and still get some pooling, I may be still in good grace. It's just that amount of oil sitting in the coupling seems a little excessive to me and has me wondering do I need to be trying to drain/mighty vac the intercooler now you know....

I have oil seepage and found very thin layers of oil in my charge pipes, that said check your intercooler, get a pump, jack the driver side up, wait 15 mjns and pump the oil out of the intercooler. You might be trying to find something where nothing is.

I recently changed out my coil packs and checked my plugs, when working near my rear turbo charge pipe, there was oil on the underneath of the plastic piping. Cleaned it off, never thought different.
