I got a new turbo on my sr20. Put it all back together and it was running fine. Later that night my hotpipe (intercooler end) came off. It was oily. Also there were little oil bubble spots in front of my intake. I had the stock Garrett T25 and now have the ISR T25. Nothing is leaking under the car or from line that I can see. Any help would be great!

Do you have an oil catch can for any PCV system feedin back into your intake? If not, you could be blowing oil through the system that way.

...either that or your turbo has some bad seals.

^^^ What he said.

If your PCV system isn't working correctly, you can actually push oil past the oil seals via excess crank case pressure.

I don't have a catch can set up. I'll try that. Also I don't see how the turbo seals would be bad . It's brand new
