same issue
I just brought my 2007 bmw 328i a few weeks ago and It was good until I started seeing smoke come from the hood and through the vents so i parked it immediately and called a mechanic . so the mechanic told me my valve cover and gasket needed to be replaced because I had a leak that was causing my oil to leak to catalytic converter which was causing smoke . I get him to replace the valve cover valve gasket and vvt and now my bmw is shaking at idle also not as much power to accelerate but with less smoke but now I'm confused any thoughts ?????
