Yes, I put everything back in like it should be. It appears that the system is sucking in air somewhere and it all bubbles back up as soon as I shut the engine down. I haven't lost power steering function yet, so as of now it is a major annoyance of a problem rather than something that would stop me from using the car. Right now, I need to drive it back to school, and I can start tearing things down two weeks from now when the quarter is over. There is definitely something wrong because it's never had any air in the fluid before. Any suggestions on where it's coming from? It has to be some place where air could get into the system, but oil couldn't leak out. Also, it seems to happen only when the weather is cold.
