engine oil seeping into the reservoir tank

Asked by GuruTFJJG Jul 20, 2018 at 11:01 PM about the 2007 BMW 3 Series 335i Convertible RWD

Question type: Maintenance & Repair

oil was getting into the coolant so we drained the coolant and oil. Then flushed the system, replaced the coolant oil, hoses, filter and reservoir tank. We finished last night. Before calling it a night decided to take it for a short drive around 15 miles or so. This morning checked the coolant reservoir and once again found fresh oil in the coolant. We have a 2007 BMW convertible turb n54 335i please help
