OK 90 xj in the past two days after i drive to work and shut off the xj the powersteering fluid overflows in the reservoir, SO first time i thought it was air trapped in the system got home jacked it up, turned side to side to try and get any air out, nothing. Next day started her up and was fine, got to work no problems, come out of work and see a small puddle under jeep, check PS and low fluid, Now today after i filled it i took it for a ride and then opened the cap, and it was under alot of pressure, could this just be that i need a new cap? Thanks for your help in advance guys

 

I had a similar problem after I installed my spacers and replaced the cap and it's been fine ever since.I would try it.

 

i had similar problem. i replaced my high pressure line. and return line. not cap. but i should . but my leak was fixed after that.

 

yeah the lines themselves are not leaking, it is just like boiling over the cap, i thought maybe the vent was blocked or something, but then i thought are PS caps supposed to be vented, might just grab on and if its not it o well
