M157 engine help
Hey guys (also posted this on the CLS forum - but there seems to be much less movement around that size of the pond)
I own a 2011/12 C218 CLS 63 AMG here in Brazil (bought it recently) - with just under 20k miles. I bought it as a future classic and because I owned an E 63 AMG 2014 W212 which I loved dearly.
I thought the M157 was the most bullet proof AMG engine (and as weirdly as it seems, that is the consensus here in Brazil - with people pushing insane builds and very few reported issues), thus you can expect my horror and shock when I began researching online and saw reports of cylinder scoring, failed timing chain, failed headgaskets.
My car has no issues (only 20k miles) though I would like to make it as reliable as possible (I intend to keep it in my garage as a future classic along with a W204 C 63 I also purchased recently).
What should I replace to ensure engine is reliable in the long run? Should I replace camshaft sensors, whole timing chain and tensioner, the seal for the coolant line in the side of the engine, cylinder head (for cylinder scorings)? Since these are all engine out services, I was thinking of doing it all at once.
Thanks for the help.

This is what I came up with but I will admit up front that we don't have a lot of hard data. We have mostly anecdotes, failures with no real statistical context and educated guesswork.

It surprises me thought that the M157 engine is so prone to failure as it approaches higher mileages.
