Got the wife's ML back today... so far so good. The rap sheet i 5 pages of R&R this, R&R that, plus a list of every sleeve, seal and bolt you can imagine... Also replaced Oil Bump & pick up tube, balance shaft (of course), chain tensioner, cam plugs, valve timing solenoid units, every fluid that flows through its veins.

QUESTION - what's up with filling the engine with Mineral Oil, running, draining then changing the oil again and replacing the Mineral Oil with typical Synthetic ? just curious what's special about MO?

Finally - what would happen if one did not have this issue resolved?
