There's a second issue that hasn't been resolved, up to and including the last 6.2L V8 that's rolling off the assembly lines.

I thought it'd be a rare event, but it happened to a friend of mine at fairly low kms and luckily under warranty. MB fixed the issue, but only for the SLS motor. When it breaks, and not caught early enough, it can be catostrophic (valve drop into cylinders).
The fix is to use SLS lifters, which if it happens under warranty, MB repairs it using SLS lifters.
Even tho it's like the headbolt issue in that it only happens to a small % of cars, it's one of the reasons I sold my BS as the warranty was about to expire. If it happened to my car and I got the updated lifters, I probably would've kept it. Scared of the ticking timebomb as I would've likely kept the car for a long time.
Well, that's pretty much removed the C63 from my shopping list for my next car. Unless of course, the fix has been done.
Is this still a problem on the 507? I thought that had SLS internals.
