probably your idle up valve leaking powersteering fluid into the intake.

funny that you say that cuz i do have to refill my power steering fluid every week or so it gets low but i cant find the leak, i dont even see it on the ground. so that could be it huh, so change my idle up valve?

there are 2 hoses coming out of the PS pump.. that valve is what is leaking fluid into the intake manifold.
2 options:

1: take that valve off (17mm) and plug the hole with a oil drain plug of the same size and the run a hose from the intake manifold to the intake tube

2:replace it

Replace valve n the hose...the hose is soaked with oil....reason why it only smoke for a lil bit is because the hose is soaked wit oil and very soft and when u start the car, the intake draws vacumm causing the hose to colapse and not suck up the oil...
I found this out when I thought it was my valve seals going bad..good thing I caught it when I was about to start pulling shit apart..

if i do this will i eventually have to replace it or this will fix it the problem for good or is it just a temp fix??

you should be fine from what im reading. the new ps pumps dont even have that valve in them i dont think. can someone vouch for this?

you can use an sc400 power steering pump that doesn't have the valve (still need to plug the vaccums). i bypassed mine with no problems. as a matter of fact i have one (whole pump w/ bypass) with very low miles for sale if you want.
