Oil change. Switched to Pennzoil Platinum Euro 0W-40. It's an API SP and meets 229.5 which is pretty uncommon (at least at this time). Found what I think was the oil filter housing O-ring leaking. It seemed like an oil cooler leak at first but where the oil pooled it really can't be. I cleaned it up and I'll keep my eye on it. Changed coolant pressure tank preventatively. Transmission mount changed just for good measure. Right front inner CV boot clamp did rub a small hole in the boot but I slathered some RTV on there. I guess I'll check it next oil change and decide if it is holding up. Brake fluid flush. Tire rotation. Broke a right rear lug bolt but was able to drill and extract (phew). Also changed some of the power steering fluid the manual way (via reservoir extraction). All of this work was easy. Tires down to 4-5/32nds which seems worse than I expected. But thanks to rotations they are wearing fairly evenly. I should probably replace them late next fall but we'll see. Should be putting the E63S back on the road so that will reduce mileage accumulation in this car.

Oil change. 9 qts M1 0W-40 Euro. Inspection notes: exhaust cam solenoids/magnets both had oil in the plugs. Drivers side will require removal of P/S reservoir. Pass side looks easy. Inspected all 4 cam solenoids and position sensors. Only these two had oil but cleaned all. Also found mystery oil mess around front right inner axle boot. Drained front diff fluid and amount was perfect. Must be axle boot. Ordered boot kit and crimping tool for $64. This will be my first boot replacement. Flushed windshield cowl drains. Inner ones were fine. Outer ones clogged. Used compressed air and shop vac. No symptoms just wanted to check. EDIT: Replaced right front inner boot. Need to keep eye on the boot for tearing against the small clamp because I forgot to push all of the air out of the joint before clamping it. It's a bit swollen. Maybe it will relax. Not a bad job at all.
