Burning oil at an alarming rate..., and yes I searched Options

[blu94gt]

So lately my car has been losing oil, I've been putting in about a quart a month to keep it topped off. No leaks anywhere other than a little oil in the spark plug tubes, but that's pretty much leftover from when I changed my valve cover gasket. No blue smoke either. Now I've been putting in a quart every 3 weeks or so, and it seems like it's going faster. Just did a compression test, was 150-160 psi on all cylinders. I've seen a lot of 5sfe's with valve seals going bad, and have replaced piston rings on other cars for burning oil.

Any input?

Car is my 99 GT btw, bone-stock 5sfe.

Well I had my neighbor look at it, some blue smoke on startup and if you gun it from idle, but I've seen much worse. Some seepage around the timing cover and oil pan but nothing actually leaking, my Maxima drips all over the place and doesn't even get to the low point on the dipstick between changes.

Car has 147k on it, right now I'm driving about 40 miles a day, used to be doing about 130 a day commute with school and work and will start that again in the fall. It's definitely more than 1 qt every 2-3k miles, but not like hurley97's 3qts in a 4 day period lol.

If it's valves I don't know if I'll try to do it myself, or just send it to the machine shop nearby for a full valve job, head grind, polish, etc (and maybe send my cams off to Webcams...hmmm). It's no problem for the car to be down and out for a few days. If it's piston rings, I'll do a whole bottom end rebuild and maybe some new pistons/rods for a little umph, maybe as supporting mods for future work.
