My 2018 went in for a RMS + oil separators at the dealer. It started leaking again after approx 2K miles. Dealer fixed it no questions asked. Take it back to the dealer. Pretty much anywhere will give a 30-90 day guarantee on repairs.

mine is going back tmrw morning, if initial repairs are done @ Benz then your parts should have 3 year parts warranty. I’m not worried I’m more annoyed, just want my car to stay in my possession so I can enjoy it when the weathers good

Got a message back from dealership, it apparently isn’t the rear main seal causing the leak but the oil separators…
Oil separators cause the seal to go bad. They must do both or youll be in this situation again.
To Benz the seal is still good, I’ve gone ahead and requested them to have another look at it, stating the seal wouldn’t leak if it had not failed and that it cannot just be the separator’s. 🤞

RMS seals have nothing to do with the root cause of your car's problems. The internal design and sizing (flow rate) of the OVSs on the M177 LS2 engine is undersized and inadequate for the quantity (flow rate) of blowby gases this engine produces. MB failed entirely when designing and executing the crankcase ventilation system for this engine (variant).
Perfect OVS seals guarantee nothing. Your RMS will likely fail again, as it has happened for other mbworld users, because the OVSs (black plastic oil and vapor separation chambers) have not been replaced.

so if they are replacing oil separators again what should I recommend they also fix/replace. I don’t need this car in the shop again over the same bs

have you read all the RMS links in the sticky? Plenty of info to guide you on what you need done; sad thing is you shouldn't have to direct them on anything they should know what they're doing ...

yes I have educated my self and read many many threads countless amount of times but end of the day I can read and say all I want and they will do what they want. I had already advised them from the beginning when replacing rms/ovs do the lines as well as they can get clogged. I’m just making sure and asking again so I can screen shot and send it to the service advisor and say look
man! Least this way I can say look I’ve been personally told that’s got to be done instead of I read it here and there.
appreciate the positivity and as well thanks for

I couldn't find any actual invoice on here where the lines were also replaced, I keep finding ones like this that are detailed but no line replaced documented:

Year: 2019 Model: E63S RMSFailure Mileage: 38K miles Style/Frequency of Driving: weekend/spirited Original Owner: No Failed Before or After Warranty: After Has it re-leaked after repair: No Cost to repair: $0 Who repaired it: Indy dealership fixed it while fixing a upper pan oil gasket under warranty. It was a while they were in there type of thing.
I am the second owner. However, I have spoken to the original owner. He said that he babied the car. I do not drive it easy. Immediately started modding it after purchase to the mods in my signature.
Update: 11 months later and 46k on the clock: Went in for a Flex A, spark plugs, and a logic test for the stock OVS. Ended up needing two coils and valve cover gasket (VCG) R&R and some smaller fixes. The VCG was leaking oil directly into one of the spark plug tubes. Pretty big job, had the VCG job sent to warranty. Warranty covered most of the repair and one OVS. I asked for the other OVS to be changed and I would pay the difference. So now, I have a newish RMS and brand new OVS's on the car. I have also purchased the 63 Motorsports Catch Cans so hopefully that will help the crankcase ventilation, and I can put the OVS and RMS issues to bed. Also, I learned the RMS isn't just the only seal that gets smoked with underperforming OVS. It also effects oil pan seals, and valve cover seals. I had an VCG replacement, and an upper oil pan gasket replacement..........
Anyways...... I have redacted the my personal information and my SA. Like I said, my local MB has always been amazing, my gripe in the other thread is directly at MB and AMG.

No problem. Like I said, I love data. I don't love the bills I keep getting and a Buick Grand National keeps looking better and better. At least I can work on that!
Do we have a sense of how many of these cars were produced and how many are experiencing this issue?
Seems like it's very wide spread and question of when not if?
This seems like a class action law suit waiting to happen, lol!?
this thread was designed to have a better understanding as non-insiders to the prevalence ... we have so little data back but what we have is fairly interesting. Anecdotally- Benz techs and warranty reps speak to countless other RMS cases they are seeing in their worlds
and I agree ... "when" and not "if" as there are no correlations based on this little data we have gathered here
