Hi everyone, I bought my 2004 Columbia Edition (US) Extrem Sport (AUS) Wrangler about a month ago and would like to drive it as my daily driver. When I start her up I notice a white grey smoke coming out of the exhaust pipe, this lasted for about 10 minutes then it started to subside. I’m not sure if it’s from the cold weather as I leave it in garage. The exhaust smoke does smell and video doesn’t do justice. Checked the dipstick no milky oil. Could it be a head gasket issue. Also there is a leak under the body of Jeep. Could you tell me the part it is leaking in picture. Really hoping it’s not something major as Im not switched on regarding Mechanical Issues. The seller may not have been completely honest regarding issues. Thank you for your time any advice would be greatly appreciated.
