White smoke when i start, ps leaking?
could this be my idle up valve?? i heard you can plug this up, is that for a temp fix or would that fix it for good? because i dont want to spend 200 plus labor fee! if it is a good fix how would you go about doing this?? what all i need to do? im use to working on carbed chevy motors so this be my first lex motor ill try to fix, any help would be cool guys
Yes, it's your AVC. Many people have plugged it for good but it does make it a little harder to turn when stopped or at very low speeds. I bought one with the intentions of replacing it myself but ended up paying a mechanic to do it. There are many threads discussing how to go about this....
Here's one:

The ones under Option B 12 in the first post? They show for me. I'm using Firefox 3.6.13.

Do you have any other symptom? I had this, started about a year ago. Once I even had the cloud pass me when I stopped about 300 feet from home! It would come and go and we found no reason for it.
A year later, there is an obvious hole in the high pressure power steering hose. It's probably been there for the year plus and didn't give me any symptoms until lately, no obvious leak for at least a year. Leak must have been tiny, ps fluid was always in the range when I checked it and mechanic never mentioned having to top it off excessively at oil changes. Just recently I have marks where I park. It doesn't even smoke anymore, the leak must have hit the exhaust perfectly at one time.
