Just bought my first DSM and having a bunch of problems

For the Overflow bubbling Im guessing its a radiator cap. Alot of people will tell you its a headgasket but in my experience its probably the radiator cap(plust that alot cheaper and quicker to replace)

For the Oil in the valve cover Id say its either a cracked valve cover, valve cover gasket or the gasket on the oil cap.
