Oil consumption/leaking in 92 M50

[colo525i]

Had my 525 almost half a year now and been through a couple oil changes. It was dripping when i first go it, so it would leak a quart every few thousand miles.

Since then I have replaced the valve cover gasket, oil filler gasket, PCV, both profile gaskets for the oil filter and pressure switch and the oil level sender gasket. I am running rotella 5-40 synthetic, and it still seems to be dripping from somewhere. (it collects on the level sender and then leaves a quarter sized spot when i park) It managed to go from half on the dipstick to the low mark in just over 1000 miles. Any other seals i should look at replacing? I don't think it is burning the oil, the plugs look normal and i have no exhaust smoke.

spray under there with parts/brake cleaner, see if you can spot the leak from the source, if its none of those you may have to replace the oil pan gasket if you havent already
