I have a 03 GT and when its idling for a period of time (say 5-10 min) and then I hit the gas it gives a puff of blue. and when Im driving around I smell it sometimes. the car only has 60k on it and doesnt get driven to hard Its only seen the track twice. Im hoping its nothing to major. what really sucks is my warranty just expired a couple months ago also. anyone have any suggestions? I quite familiar with the 5.0's but the 4.6 is a different animal to me. mods are accufab 75mm, MAC plenum. March SFI u/d pulleys, JLT CAI, SCT tuner, and o/r Xpipe and cat back. I quickly checked my PVC valve but honestly I dont really know what to check for.
