Sorry I have been asking so many questions, but here is one more.

For a while now(I dont know how long, I have only gotten into cars about 6 months ago) a car my family is borrowing from a good friend while they are in a different country has been having a few issues. The car is a 1993 subaru loyale manual 200k. Issue 1 that I am aware of, is when I am idling the car shakes like there is a person on each side pushing down on the sides of the car. I suspect this to be a motor mount, but at the same time considering the other issues it could be a misfire aswell, though thats iffy. The second issue I notice would be something I am not sure if its an issue so much as a quirk, but when I am starting the car and accelerating from a stop light the car makes a kind of coughing noise(closest I could think to what it would be) coming from the exhaust, aswell as sometimes a lack of power. I know this is only an 80hp engine, but I think it should be a little less stuttery than it is. The third issue would be a very oily engine, from around the valve cover gaskets. it is on both sides of the engine. I dont think this is a huge leak, but it is very oily. also I dont know for sure if this is just something with a manual car or a sign of a dying clutch, but when I start the car and try and put it into reverse it makes a grinding unless I put it in 1st beforehand. issue 4: power steering being very inconsistant, when I try to turn from just turning the car on/sitting for a bit, it makes a whine and sometimes feels like the power steering just isnt working. Oh yeah and the car had a mice infestation in the hvac and we cant find the source of the huge smell coming from it. I know its probably not worth fixing everything on this car, but I would like to know if there are any solutions to these problems I have found with it so far. Sorry I have been posting so many questions, but I find this a good outlet for me to find answers to car questions I have.

Thanks for reading.
