Mercedes Scottsdale (The only AMG Performance Center in AZ) charges $290 a hour. Alpha Warranty only covers $210 an hour so I have to pay the difference.

The OVS tested good. I do have the updated RMS part.

It is just super disappointing that this car will have almost 10K in repairs to leaking gaskets. An upper oil pan gasket, a valve cover gasket (roughly 10k for both). Add in $5600 for an effing headlight, plus $2700 for a windshield....all in 11 months. All covered by insurance or warranty, but geez......

If I ever go with another 63 series AMG and I will probably only lease one in the future at this rate.
It is nutty
I just had the purge valves done today
it's like every 1-2 months E63 needs something

Need the guys that put on 100K miles plus with "not many issues" to chime in on this thread.

Let me be transparent. The $5100 was the quote for the VCG reseal. I haven't paid it yet. Hopefully tomorrow the car will be done, and I will have an actual number.

It is really disappointing honestly. I have a stack of maintenance records for this car since it was new. It has also had it's service ABC's, diff service, ect, and still there always seems to be something.

On a lighter note, user @legegendary91 owns a commercial livery-driven W222 2018 S560 with 490,000 miles. Impressive to say the least!

LS1 engine, but still...

It points to the crappy OVS system as a limiting factor to longevity with the LS2 engine. The LS2 crankcase ventilation system is undersized for the blowby it generates.

Hopefully the 63 catch cans will help with that. Only one way to find out.

there was some theory floating around that seemed interesting that these cars that are commercially used like limousines or taxis overseas in Europe, the engines are constantly running so the oil is always at ideal viscosity and there's no cold start ups, etc., etc. and I could theoretically see how that would be ideal for the longevity of the engine. I totally understand your point about the crank case pressure issue.

I have an update. I spoke with my SA and I had him go ahead and replace the OVS's (out of pocket) since they were in there.

I am paying for a routine service (oil, filter, ect), plugs, two coils, and both oil separators + the labor for those items. Plus the two year warranty on parts esp the OVS's is nice.

Alpha is paying for the VCG replacement and reseal. I will let you know the details when I pick the car up.

My loaner has been pretty cool. 2025 GLA 35 AMG. Cool for what it is, but shouldn't have a AMG badge honestly.

Scottsdale Mercedes and my SA have always been amazing, and they have always been stand up. They communicate well, and they always put me up in a higher end loaner. I have zero issues with them. I am actually going to request to meet the tech that worked on my car, so I can apologize for my E63 being a c u n t, and give him a tip.

I have mixed feelings about the quality of simple things....like seals and crappy crankcase design. I honestly think MB needs to have a recall and fix this, or someone with deeper pockets than me needs to file class action, because this is a major problem.

Yeah. I have usually found if you get in good with your SA and you find a tech you trust (and then request them in the future and take care of them) it will usually pays dividends later.

Okay. Here is the update. I have redacted the my personal information and my SA. Like I said, my local MB has always been amazing.

OVS were replaced. I bought one and my warranty covered the other. Service Flex A, Spark Plugs, Two Coils, a couple of connectors.

Warranty covered most of the valve cover R&R and other things.

For pre '20 E63's I think the catch cans are a worthy investment!

Seems like more cam carrier (aka "valve cover") leaks are being reported. IMO this is a symptom of crankcase overpressure and failed RMS. Catch cans are the answer to correct crankcase pressure, but uncertain if they create unwanted collateral effects.

M176 cam carrier leak into the spark plug bore is not hard to find reported on this site.

I asked my local Merc dealer if they were interested in installing the 63 Motorsports Catch Cans. They declined and sent me to Dyno Comp. So on Monday the car goes to Dyno Comp to have them installed. Once they are installed, I will start my own thread about the cans.

Stealership would never.

Very curious about when it comes drainage time of the cans.
Looking forward to your thread.

Would installing a catch can system cause an issue with Fidelity's warranty coverage of my MB 2018 E63S?

I have a pretty good relationship with my local Mercedes Dealer. They did take into consideration about my past issues with gaskets ect, and they did speak to the SM. In the end, they said no. My E63 would be going to Dyno Comp today to get the cans installed, but 63 Motorsports did not send the drainage tubes with my order, so I am waiting for them. Also, I am waiting on a Gen 2 Black Boost Intake to arrive this week. Going to have Dyno Comp re-tune the car for the intakes and add a rendition of their E30 tune as well. With my mods this stupid car better trap 130 mph + when the temps here in Phoenix come down.

Once everything is in the car, I will post my thread.
