Oil leaking from turbo

[wannabeS4]

Hey guys recently put my motor back in after having the trans rebuilt. I noticed an oil spot under the car after pulling out of my driveway. Put the car in the air and noticed oil leaking from the bottom of the turbo. Turbos are F21 with new chra with about 2k miles on them.

On the d/s turbo one of the bolts holding the compressor housing to the turbo was loose. Bolt won't thread in so I'm guessing the treads are gone. Was thinking of just using a bigger self threading bolt to fix it.

Did you remember to tighten down your oil feed lines?

If it's leaking out of the bolt hole on the compressor housing your seals are shot. Only 3 places it can leak oil from on turbo are oil feed line, oil drain line, or seals. Not too sure how the CHRA would be blown after only 2k miles though... Check the lower intercooler hoses for oil

That's what I was afraid of. Every other place is dry so it has to be the seals. I'll give the lower intercooler hoses a look.
