03 wrx overheating and oil smell
About 5 months ago I bought an 03 wrx with122,000 on it. I took it up to the mountains about a month ago and once I got up there noticed that it had started to overheat once I got the where I was. I looked into the coolant reservoir and noticed that it was pretty much empty. I topped it off and it ran great until about a week later when just driving it in town the temp gauge started to climb. Again I toped off the coolant and it was fine. And now it happens about every week. I have also started to smell a strong smell of oil after getting on it. It randomly will miss fire when I start it but stops right away. I don't know if they are all connected or not but from the little mechanical experience u have it sounds like a head gasket to me but I don't know much about these cars so I was wondering if anyone has any other suggestion before I pull the motor apart. Any help wlll b greatly appreciated thank.
