M276 Engine
Came across this and found it informative. The video is mis-titled as it is about the M276 engine across all platforms.

Some things I thought could have been discussed in more detail, but I think they were trying to keep the video under 10 minutes. A big difference between the NA and turbo engines is the ease in which to change spark plugs on the turbo engine -- no need to remove the intake air plenum.
There is a good little nugget that talks about the dipstick popping out and a clogged PCV valve being the likely problem. I've had this problem for over 75,000 miles (current mileage is around 127,000), so I put it on my maintenance list to replace when I do the HPFP.

I searched and personally I could never find the "oil cooler O-ring" at Tstat that brings up the hot coolant from heat exchanger... it's one good seal to replace! It brings in super hot coolant with high piston's heat. Removing heat with cooled oil is an old-fashioned way. 
I looked up and found that part on MBUSA only complete hose that had no ¢50 O-Ring option for sale.
The PCV that pops crankcase dipstick is 90% caused by blow-by pressure fixed by sealing cylinders with clean wet rings, the way that's always worked.
10% from the flat plastic pipe between PCV to intake is the one that does plugs up with burned oil deposits.
TT vs. NA are radically better at filtering oil vapors with dual-rate PCV system. NA uses entry-level PCV for results we know.
The quick chain TENSIONERS want to meet you or your MB specialist. They are absolutely money super well spent along with the complete serpentine kit.
The host Mr. Kyle/FCP does not cover suspension parts (separate video available). They are cost effective way to enjoy normal handling and braking. + FWD CONTROL ARM
+ STAB BARS
+ LWR BALLJOINT.
Rear Diff, tranny, 4Matic always appreciate clean fluids before any damages develop.
ALSO nothing about CPS oil-in-harness, plastic coolant tank, radiator... are all directly related to heat and pressure issues... a common theme

yes, very true, Turbo plugs are a walk in the park.
However, due to the placement of the turbo system's air to water intercooler and the accompanying hoses/reservoir, the serpentine belt/tensioner/idler pulley replacement on the turbo, is an absolute nightmare of a job.
