Further update. Now have about 13,000KM on the rebuild, still have that annoying oil leak. Have put dye in the oil, most oil seems to be collecting at the bottom of the engine, between engine nd transaxle. cant really get to see from the top of engine where the oil is coming from, just cant seem to get in there. The back of the engine is damp, at least until you get to exhaust manifold, cant see above that. There is some oil dampness on the head just below valve cover, so seems to the pointing to the cover, although the amount there doesn't seem to fully jibe with the amount that is actually dripping off the engine. Going to remove the cover, and closely inspect it, have seen some posts online about the valve cover itself warping or cracking
