My 07lbz is churning blue smoke during idle. I changed my exhaust this week to 4" turbo back straight pipe (sounds Great). I have noticed it after getting off of the interstate,sitting in line at the drive thru. And during start up. I run my predater on 85. I havent put my finger stick on yet. I was thinking that may be the prob. dunno maybe someone can help me on this. Also after start up I noticed what seemed to be a noise that sounds like a compresser kicking on but the a/c was off. Thanks in advance.
