So I uploaded a video a few days ago of smoke coming out of my exhaust. Everyone was telling me it was likely turbo related, possibly a head gasket. I did one of those liquid head gasket test, and there was no detection in my antifreeze. There’s no oil in my inner cooler or antifreeze in the oil as I just had the oil replaced. There’s no leakage coming from any of my turbos. Everything is nice and dry. I have boost. So I ended up taking the spark plugs out and they look pretty bad with oil surrounding them. I guess the seals are no longer good and are allowing oil to get into the spark plug. I am just assuming here, but I would assume this is why I was getting smoke out of my exhaust that was burnt oil. Would this be the correct Fix changing the valve cover gasket and seals? Does anyone else have any advice as to what could cause this?

Over the past few years, my 2017 F150 eco-boost has needed the driver side upper O2 sensor replaced at least twice a year. I thought this was very odd, but I do have a bola exhaust system from the turbos back. For the past week now I have been seeing excessive smoke and an oil burning smell coming from the exhaust. There are no visible leaks on any of the turbos, and I still have boost and power. While the truck is idling, clouds of smoke come out of the exhaust. I did a cylinder head test and everything is fine. Is there a way to connect forscan to tell if a turbo is bad or what side of the turbo is bad? I saw someone disconnect their downpipe’s and give the truck gas and where they saw smoke. They figured that was the blown turbo. Is there any easier solution to this to find out? Most people are telling me to keep driving the truck until a turbo goes out, but I do not want to cause any further harm to the truck as I have over 200,000 miles.
