My GUESS is clogged oil control piston rings. Other than a good used engine I'd try a couple of motor flushes with Liqui Moly engine flush.

clogged oil control rings would be quite a show on a mercedes benz M272 as the rest will have packed up way before that. (the cylinder heads and variable cam timing dont like bad oil)
