the power steering pump cannot leak into the engine oil, the PS pump and VAC pump are seperated by an 'open air' coupler. If the seal leaks, it will piss out onto the ground.

If your engine oil is going up (and no obvious sign of a milkshake antifreeze brew), its best to send out a sample for analysis, its possible you have fuel contamination

could be from a f'd injector, worn out rings and excessive idling, injection pump, lift pump, ect.

I'm surprised you PS system is not foaming over. Engine oil is not meant for that application.

pretty much anything works in them... LOL

When i popped a pressure line a few winters ago, i was 250km down the lake at the drill site. Only thing we had onhand was a bunch of 15w40 and i was driving my truck back to town that day come hell or high water.

10gal of 15w40 later, i was home with brakes and power steering the whole way. worked like a charm other than filling it up every few miles LOL

A little off from the original post.

Have you cracked any fuel lines to the injectors to bleed the air out and see if you are getting any fuel? Keep priming.

Engine oil absolutelly should not be used in PS, unless extreme emregency. Yes it may seem to work on a limited basis. The needed additive pachages are very different. JMHO of course. You can use horse wizz if you like, just hope I and no one else is in the path when something failes.

Let him keep believing it needs a new p-pump, buy it real cheap, than fix it for about $20. Learn to use the search feature, read the beginner's thread and you will be golden.
