I took it in to my mechanic today and he told me not to do the work. He showed me a blueish foam in the coolant and a yellow film on the oil cap. He also showed me how the dipstick was waaaaaay overfilled likely due to coolant leaking into the oil. All sure signs of a blown head gasket...right?
On top of the CSP sensor and the plugs, wires, and valve cover gasket...this 96 Saturn just isn't worth it.
