mini update on mine leak ...
Dealer foreman got the advise from MB Germany that whenever there is an oil leak at RMS, the two oil separators should also be replaced as it would be a matter of time before they would also fail, the quote I got for this task is 8 hrs labor and with parts at $800 Cdn. Currently, the two oil separators show no signs of oil leak but I just don't want to go thru this hassle in the future, so I approved the dealer to do that repair at the same time.

2018 W213 E63S Sedan -39k - ALSO mean seal leak.
I just had a video sent to me from Euro Motor cars of Devon PA. My Brother and I both ordered our E63’s new from there. My car is fully optioned, but completely unmodified (my Brothers is modified). My car has 39k relatively easy miles, is FULLY maintained, has been garaged its entire life and I have other cars for any time weather is inclement. So, this should be a cream puff. It is leaking from rear main seal. They quoted me $8900 to fix! It’s just seeping right now. If it continues to get worse… if this is Mercedes’ “best or nothing”… time to move on from Mercedes

I should ask my Service Advisor later this week to see how many Amg (all classes with the 4l v8) he has seen thus far for RMS repair.
mine is scheduled to be completed by next Friday (almost 4 weeks at the dealer, waiting for parts here and there)

From what i'm gathering, preventatively replacing the separators I guess is the way to go here . Not an easy or cheap rodeo by any means , but if it can prevent the rms leak maybe worthwhile . Seems to be no way to tell when/if they're plugged so it's a roll of the dice. Quite a few carfaxes show rms' done in my search for a 213 - seems to be quite widespread.

car is finally completed today (01/16/23).
Dealer has given me the final bill on this RMS & Oil separators repair bill
28.5 hrs labor @ $176 per hr = $5,016 Canadian
Parts = $773.50 Canadian
Total - $5,789.50 Cdn or $4,321 US (in today's exchange valuation)
Grand total with sales taxes (13% where I am) = $6,542 Cdn
* RMS parts replaced - sealant, elastomer seal and new crankcase cover and bunch of bolts/screws
* oil separators replaced - oil separators, belts, vent line
Dealer made a remark on the bill of the RMS failure due to crankcase pressure vacuum was too high

You have to ask whether extended warranty will cover this. My dealer (Servicing dept) is not 100% sure if this is a warranty item, I guess he would have to call up MB Canada to get confirmation.
Back in 2021, the extended warranty for our E63s price quoted was C$5,250 for +24 months // C$6,200 +36 months .. taxes not included
Not sure what the latest quoted price for that now

The argument to MB for coverage of vapor separators is that they are an emissions component. If they disagree, I’m sure there are many lawyers who would gladly write a polite letter to MB that would get their attention. Include the EPA in carbon copy.
Remember the small block Chevy V8 in the 1968 Chevelle, and its PCV “breather”? Fast forward 55 years and we now have vapor separators.

8yrs/80,000miles coverage for emissions components, if the vehicle has failed an EPA short test.
Because the examples in this thread are not preceded by a failed EPA short test, MB will push back on coverage. Therefore the lawyer letter might help toward partial or full coverage of the expense. Also file a complaint with NHTSA.
This is for 2020, I imagine a document exists for each year:

Oil separator is listed.

Can these 4 oil separators theoretically be unhooked to avoid this issue all together?? Yes I understand as far as emissions and warranty is concerned you can’t do this but speaking solely as a permanent solution to the separators being the culprit of the RMS failures thx I’m advance

Pressure needs to be relieved from the crankcase, so disconnecting the separators and plugging the holes in the cylinder head is not an option. The separators could be removed and an aftermarket catch can plumbed from the cylinder head holes, or the factory vapor plumbing between the separator and intake manifold could be rerouted to a new aftermarket catch can.
The second scenario still leaves open the potential of plugging the factory separator and blowing the rear main seal from crankcase over pressure. So it’s back to a full-on aftermarket catch can solution. MB didn’t get it right. Again.
The above is the hardware scenario. I don’t know if there are sensors or switches connected to the separators or plumbing to the intake ducts.

Yes there is plumbing into the intake ducts.
