Oil leak from centrifuge housing - really?
Hey Everyone,
I took my 2014 E350 4Matic in for service, and $1200 later they found a small leak coming from the oil separator (centrifuge housing). The service advisor said a small amount of oil is leaking into the intake so I should not let this go unresolved. too long. The part is about $60 but the labor is $2300. This part is external to the engine but supposedly requires a lot of labor to reach.
Has as anyone has this problem? Is the $2400 repair price reasonable?
Thanks for you feedback!

Hey, I took my car to an independent service shop and he seems to think that it's unusually early for this type of leak to happen, but also thinks it will be straight forward to fix. I'll take it back later in the week for a full diagnosis and repair estimate.

The car has 61K miles on it (had 40K, when I bought it) so the warranty has expired and I did not get an extended warranty. My initial thought was to keep it until it got about 75K miles on it, then move on to the next.
The independent said he's booked until Wednesday or Thursday. Fortunately, I can walk to work from there so logistics will not be a problem.
I'll post an update once I know more.

^I think you're right
I'm pretty sure I had this same issue and was only charged 300 bucks in total with Labor on my 2010. Also at the time I was told it was not a big deal and could be put off until later. Which is a rare statement coming from the dealer. I have to double check my receipts when I get home since I could be talking about a different part.

Update (years later ; )
Hi @Johnbwilson1. Very long shot, but I’m curious how this was resolved in the end. Thanks!

service the crankcase vent and reduce crankcase pressure ("MOD-2")
else engine will start venting high blowby pressure from next seal until $5 rear seal requires pulling engine out.
MB USA fixing old cars for free is a remote hope.

Yes, much worse. There’s a lot to love about the facelift 212s, but the location of the centrifuge and the engine oil and oil pressure management that results in camshaft and timing issues are not among them.

centrifugal PCV
Newer "API SP" oils are formulated to burn cleaner with less ashes.
It's no match to stop M276-NA blown-by vaporized 0W-40 oil stream.

It's the heart of the Mercedes PCV system... it is supposed to sling shot oil around so it doesn't end up through the intake to contaminate cats & lambda.

hmm, is 5W40 any better? I think thats what our E350 has in it? I've never liked the idea of 0W oils, and it hardly never goes below even 0C here, never mind below -25C. In fact looking at https://operatingfluids.mercedes-benz.com/sheet/224.1 it seems like we could be using 15W40 or even 20W50 for our temp range. I used 15W40 in our old W124 M103 and M104 engines....

The newest trend is that "limited oiling saves gas" - Yes, 0W-8 sure does! It's a good deal for leased fleets.
However, the oil film thickness can not be replaced by polar Zinc/Phosphate chemistry attracted to steel or Moly/Boron to Aluminum - They can only help!
Currently I am running an 15w40 SP rated lubricant to limit oil vaporized back through intake valves.

So you have to partially drop the engine as suggested to replace it?
