Hey, I'm New To The Forum,i Am A Proud Owner Of A 2007 Crossfire Coupe With 14,000 Miles, And When I Crank It Up, It Lets Out A Puff Of Blue Smoke. I Had It To The Dealer And They Tried To Tell Me They All Do That And It's Burning Off Carbon, Anyway After A Little Discussion, They Replaced The Valve Stem Seals. Has Anyone Else Had This Problem?
