Well, I have finally fixed all of the oil leaks on this car over the last 100k miles. It's nice to have a clean engine compartment for a change, but now I still have to figure why the following is happening.

After fixing/replacing the PCV system completely in the vehicle with all new stuff I found that was my major oil leak. The local service shop put a hose clamp on so tight that it ripped right through a hose. (not good)...

But anyways,

After fixing this I did an oil change, but before I did that I did an engine flush to clean out the junk that may have been in it. Then drained it all out, put new oil and new filter on. For the first time in years the car actually registered the oil correctly on the dip stick. And after checking it daily for a week everything seem to be fine. So then, I did not check it every day but every couple of days, now about 2000 miles later I noticed that I was about a quart low, but absolutely no leaking anywhere. I even watched the exhaust and I had absolutely no smoking or color coming out of the tail pipe.

Does anyone have any clue on why I'm still eating oil? What do I need to check?

It is a 1995 Volvo 850 GLT Sedan with 374K miles on it.
