Archived Oil In Power Steering??

[ELake]

Noticed my truck is starting to leak a ton of oil from the power steering pump. Upon further inspection it appears that engine oil has somehow entered my power steering unit and flowing out the top of the ps pump (overfull) Is this possible? I recently replaced the vacuum pump seal and all was well until a couple days ago.

I run rotella T and before with nice shiney red power steering fluid. . The stuff is now black as sin and smells like rotella and is pouring out of the cap. I searched and didnt yield any results could my vac pump be toast?

Guess I'll atleast order up another seal kit from cummins but im wondering what caused this? I thought the vac pump recieved engine oil from that fitting on the bottom of the vac pump and then pukes it back into the engine thru the front gear.

Thanks in advance!!

took it all apart... looks like its physically impossible for this to happen.

I think the bottle of mercedes benz power steering fluid I used was probably oil or something. I need to reseal the coupler. seal must not of been seated properly... but the shafts look good no scoring or anything

reseal and problem should be solved. I'm also going to flush the system of that crap and attempt to put a new pitman arm seal in...

crisis averted!!

Can you see any leakage from the vacuum pump that you just rebuilt.
