After finishing an uph cleaning job w/ Hydramaster cds 4.8 as my pto, noticed power steering fluid leaked and left a mess on the driveway. I saw the resevoir had leaked during the job. I was backed up a decent incline, which is uncommon for me, so I am hoping it was from the incline causing the vent to be blocked to cause this? 2016 Chevy Express. Also, the oil level is still ok which im leaning on it was overfilled to begin with, a while ago.
