Anyone install dual catch cans for RMS leak prevention?
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.
I just had the purge valves done today
it's like every 1-2 months E63 needs something
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.

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.

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.

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

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