Ok I have not post pic of my ride but once i can i will. I got the mustang about 5 mouth ago and i realy love it.The problem i have is once i trun on the mustang some kine of somke ( its like white and gray ) comes out of the rear pipe exhaust and then leaves it. When i run the car it does not do it. I check the oil level and it looks ok. It runs nice and do good burouts any way that i notice that it had like a bit more power ( maybe its me). I was told that i have to change the valve stem seals( my ride is a 2000 gt automatic with 48,500k run). If i do this what other thing i have to buy or do so every thing will go ok. I mean do i have to change valve lifters, spring,rocker arms and roller , camshatfs. Plase if any body can help me because i do not understang mechnic and were can i buy all this.

Its really hard to tell what that could be without really looking at it, but it is probably just a small oil leak that burns off when you start the car. If the oil level is ok and everything else seems to be ok then its probably not a big deal. But, its better to be safe than sorry so I would suggest taking it in to a shop to get checked out.

Well when i leave the car overnight and start it the other day it does somke a littel until the car worm up until it disaper. Then i can ride it a few miles trun it off and when i start it comes out that white /gray somke yust small amount and stops. It does this simo times that all the times.
