That's a great idea, except for two things. There was never a "factory class" for the M120 V-12. Also, given the rarity of these cars, finding an MB tech who has worked on more than a handful of them (not just routine service) will be very difficult.

I think you should take a closer look at the crankcase ventilation system. The entire ventilation circuit should be carefully checked. Maybe monitior manifold pressure. Is it different when the problem occurs?
