Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Sounds like you could have an oil cooler with a leak - causing intermix of oil in your coolant. Have this checked right away. Systems need to be flushed and a faulty component replaced. Certainly, a diagnosis hands on should be done first. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
