So today I removed the intercooler on my 2002 WRX and noticed what appeared to be oil in the outlet that goes to the throttle body. I smelled it and it smelled like oil. also on one of the inlets on the back the "y" hose was covered in the same oily substance.
Upon further inspection i noticed more oily residue on the inside of the turbo outlet. I figured I should check the oil which was just below the bottom dot on the dipstick.
I just changed the oil about 200 miles ago and put in 4 quarts of mobil 1 as the manual suggests. 15 minutes or so after the change I checked the level and it was just below the top dot so I assume i am burning some oil.
I haven't driven the car hard at all and it is holding boost and otherwise seems to run fine. There are no oil drips anywhere and I have not noticed any smoke. Any ideas what this is or how to fix it? Is it possible for there be an oil leak in the turbo?
My car is stock except for Mishimoto radiator and silencer delete.
Thanks for any and all help
