is it normal to find oil in your intercooler piping, that runs through the maf to the intake manifold???

a little bit of residue, sure. But if its dripping out or pooling up at the lowest point of your system, no. It means you are pressurizing your crankcase and all the stuff thats supposed to be going to your catch can is going into your induction system. Probably need to re-route you PCV lines, etc..

i have a nissan nx2000 has this happend to anyone else besides me???

yes...thats why i answered. lol Last time I took my IC pipes apart I had a good amount of oil , which led me to realize I was pressurizin gmy crankcase and I need to re-route my PCV lines

^^^^^ Yep...... pics of your setup would help a lot. I have also seen this when the seals on the turbo have had it but that was a lot of oil.

my engine had like 1000 mi on it after rebuild and i had oil in my piping. as long as your pcv lines are all correct sounds like time for a turbo rebuild

yep happened to me, had to rebuild my turbo. check out GPopShop.com they sent me the exact kit i needed and are fairly well priced easy to deal with.

If oil is in the PRESSURE pipes the turbo seals are bad.
