Question, Can motor oil get into power steering pump? one thing is for certain, about every 500 miles I suck a few ounces of oil out of pump when it starts leaking out cap, and its good for another round until it gains a few more ounces,starts leaking and it come out black. I did change vacume pump seal about 150,000 miles ago. its been doing this for several months, I have tried bleeding system and no luck. My brakes and steering seem to be OK.

 

Hi 01cummins4ever,

This problem does not sound normal. We would respectfully suggest that you have your vehicle checked out by a qualified technician.
