Hey guys, I have a problem with whenever I shut my truck off the PS resivour pukes fluid out, and she leaves her mark where ever I go, I have done a little research and of course it could be a few things, bad pump, accumulator or hydroboost, I already changed fluid and bled system, Done a hydroboost check with brake pedal, ( test came out kind of iffy) The steering does work but will stiff up under a heavy load, the fluid gets a lot of air bubbles ( like cavitation?) The hydro boost does not leak and my hoses seem to be in good shape, Any idea what to replace first, hopefuly not the hydrboost those things are pricey

 

so... nobody has had this problem? Let me rephrase, It is blowing oil out resivour cap, and is it possible to leak engine oil into power steering pump through vacume pump?
