Hi all, I purchased a Bmw 320i 2007 with 80,000 km on clock. When the car is running I noticed some smoke coming out from the engine bay. So done some research and found that it could be the valve gasket is leaking oil. Was wondering if anyone knows someone or a mechanic around West Auckland area to fix this issue. And roughly how much would it cost for labor + parts? appreciated if you can help me.
