Author Topic: Engine Noise White02GT ¯ Member # 611 posted                              After I drive my car for a while, at times it sounds like there is a valve blow off and its releasing pressure. My engine is stock, my only mods are x-pipe, flows, and now a shifter. It only seems to do it when the car is warm, and has been driven for a while. Any ideas? -------------------- 2002 Mustang GT 13.54 @ 102 "You can't out smart a smartass" Eminem Posts: 1984 | From: Mountain View, Ca | Registered: Dec 2001  |  : jayl ¯ Member # 185 posted                              must've got one of those TDC stangs slipped onto the dealer lots for testing........ -------------------- Facebook.com/TeamTemporary 8.5's TTFBitch!

Like a blow off valve?? When does it do it, idle, cruise,WOT?? Could it be anything A/C related, like the compressor coming on/off?

I'm not sure what it could be, but it does sound like pressure is being released from something. -------------------- 2002 Mustang GT 13.54 @ 102 "You can't out smart a smartass" Eminem Posts: 1984 | From: Mountain View, Ca | Registered: Dec 2001  |  : JoeT ¯ Member # 298 posted                                 only thing I can think of is either PCV valve is like blowing out the back, and then back in or something. your valve cover breather/TB thingy is doing something similar or ITS TEH DAMN AC MAN!

When it does it again, I'll make sure I remember everything, and tell you what's going on. -------------------- 2002 Mustang GT 13.54 @ 102 "You can't out smart a smartass" Eminem Posts: 1984 | From: Mountain View, Ca | Registered: Dec 2001  |  :
