I have a question regarding a 2013 ford fusion 1.6L ecoboost. I recently replaced the valve cover gasket on it due to oil leaking into spark plug and fuel injector well. And that seemed to fix the oil leaking. Im going to replace the fuel injector top and bottom o rings and see if that fixes it. But very little white smoke comes from the fuel injectors and im assuming its because it was burning residual oil left over from the valve cover leak. Thats one of the reasons for the replacement of o rings. But i also assume its combustion fumes from the cylinder head coming out from the fuel injectors. I can send videos to you if you need them.
Well you can put ultraviolet leak dye until the engine oil and then you can see if it comes squirting all around it's from an engine oil leak if it's burning you wouldn't see the die only if it's leaking
