I am doing the PCV maintenance on my XC90 w/6 cyl.
After getting it all tore down , I am cleaning the ports that go back into the engine & I cannot get the bottom port clean. I can blow air through the upper & the one off to the side . I have used compressed air & a shop vac to get it to open up .
Have any of you had this much trouble with this repair ?
