this being a turbo It does not surprise me. at 80k your turbo diverter valve checked. its one of the most comman issues for turbo's sucking in oil. first one looks like you already looked after it which is the valve cover. tho i would say if it started to do it only after the valve cover? if it did then perhaps the seal is not on it right.
