It's not hard to remove the downpipe from the EBPV. Get a 8mm 12-point wrench and remove the EBPV from the turbine housing by holding the wrench on one of the three bolts holding it on and tap the open end of the wrench with a small hammer or large rubber mallet till it breaks free. Remove EBPV from the system and pull the rubber inner boot off before the turbo on the other side. Reach in and spin the wheel, does it spin freely? Push in/pull out on the center of the shaft/wheel and try to rock the wheels (intake and exhaust wheels) to check for play. No play is great, very little play is ok, if you have play in any direction apply force in that direction and rotate the wheel to see if the play in the wheel is allowing the wheel to scrape on the housing that the wheel is in. Look at the wheels for chipping, pitting, bending, missing parts/fins.
