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
there is no upper intake gasket, only a front and rear
There are many ways that you could change the front grill of a vehicle. You could replace it or decorate it.
No, the engine doesn't have to come out.
The vehicle speed sensor is between the transmission and the engine from the front of the the engine bay, there is also a vehicle wheel speed sensors in in each tire
No. I had a Saturn of that year and the handbook warns against it. no front wheel drive vehicle should be flat towed (using a chain or strap). It will damage the transmission, much as towing an AWD or rear wheel drive vehicle without disconnecting the linkage. The best option if towing a front wheel drive vehicle is to use a car dolly, or call for a wrecker or rollback truck.
The oil filter on a 2008 Saturn Astra is located in front of the engine. The oil filter can be found on the underside of the exhaust manifold towards the passenger side of the vehicle.
i think its located some where in the front of the vehicle usually by the bumper or by the radiator , caution not in the radiator but maybe attached to it .

Take it to a transmission shop. Depending on what you mean by front gasket, it will probably involve removing the transmission. Again depending on what you mean, it is most likely an indicator of a bigger problem.
Need to know what year, make and model vehicle you have.
Where is it leaking from? Could be front or rear seal or coolant lines Did you change gasket when you changed fluid?
there is no lower intake gasket, only a front and rear gasket
