The filter cap will be brocken and oil can leak through that way
just change the filter cap
Yes, it could be. Regardless where the leak is, it should be repaired.
If its coming from under the chrome cylinder head cover, its the head cover gasket.
depends on the car, typically just the valve cover gasket though
Assuming you mean "valve cover gasket", the gasket seals the valve cover to the head so as not to leak oil.
An oil leak there is probably a valve cover gasket leaking. it would not require head gasket replacment. Try tightning the bolts on the valve cover. If that does not work then replace the valve cover gasket. Yes it could be the head gasket as there are oil passages in the head and i have heard that head gasket on saturns are prone to failure,look around the valve cover for sings of a leak hopfully that's all it is because replacing the head gasket is costly on th 1.9 sohc
it depends where you go and what or where is the leak. you know that if is where the cover and the cylinder head meets just buy rtv sealer and put some on. if is the cover it self(craked,rust,ect) just buy a new cover aprox $30 the most.
the signs of a valve cover leak are oil on the engine oil is the only thing that can leak from a leaky valve cover
Defective cap? Bad thermostat building excessive pressure
No, if there is coolant in your valve cover it'll be mixed with oil. You blew your head gasket, possibly warped or cracked your head. It may look like coolant is leaking from your valve cover but it's your intake gasket leaking.
You possibly have a leak in the cylinder head gasket.You possibly have a leak in the head gasket.
Head or head gasket leak
Any internal coolant leak can cause a milky residue in the valve cover. Head gasket, intake gasket, cracked/warped head, cracked intake are possible causes.
