I have an C63 Coupe with the M177 and 165.000 Kilometers mileage. Now it is 8 years old and it works.
Didn't any problems occur during this period?
@@jghjvhhgj1912 I also have 100k km on my 2019 C63 S Sedan, can't complain
Nice Video. Your are the best!
Get ittttt! Love the production
These guys are the best! If you’re in the New England area and want your Mercedes serviced this shop is phenomenal.
I would highly recommend replacing the plastic intake manifold. Weistec has aluminum replacements. So I’m looking at the Aston Martin vantage that has the m177 or a s63 amg. So I want to get an idea on what to take care of before doing full engine rebuid. Doing forged piston, rods, aluminum intake manifold. Upgraded turbo kit and down pipes. But want to replace all seals and main failure points first while engine is out
Did not see aluminum replacement M177 intakes on the Weistec site. Do you have a reference to them?
Well done lad
Engine mounts replacements on this engine reminded me of the M275 engine mounts, difficult as a mf....
It would be interesting to know if there are any better engineered replacement parts for these common issues.
Excellent video.
I have an m176 and its at 75k.
Replaced the plugs at 50k but no oil on the covers.
Mine its tuned.
II do early maintenance on it.
Curious if the valve cover leaks are related to excessive crankcase pressure created from clogged air oil seperators.
Great information, thank you! I have the GLE AMG 63s SUV and it’s phenomenal however I noticed it’ gets extremely hot on a summer day in Florida
Very good topic.🎉 Is the V12 Bi-turbo any better or does it have the same issues? I'm thinking about purchasing the SL 65 AMG black series as a collector.
A video outlining preemptive fixes or upgrades to address the issues (if any) would be welcomed from those of us who want to keep these cars longer term
Good information.. I remember a time when Mercedes 8 cylinders were bulletproof and reliable (sort of) M117, M119 and even M113
Hell, this makes my M156 look like child's play.
The M112/M113 and even the M113K are all PROVEN 500,000+ mile engines. The M113k needs to have it's supercharger maintained sure, but they are all just so overbuilt. You can't kill them. When I got my first CLK 55 AMG with it's M113 under the hood, it blew my mind how simple it actually was. The Valve Cover breather boxes need resealed every now and again but that's really it. Having two-spark plugs per cylinder and adding a ton of compression is like magic.
@@ftffighter correct, 135K miles on my E55 and zero mechanical issues other than airmatic pump and supercharger bearing. i never beat on it from a dig, but have run it 130-140mph many times..
My 2017 (at 51,000 KM) recently started belt squeaking during startups, the squeak gets softer and eventually stops after around 10mins of idling or temps reach around 40-60celcius. Any helpers please.
There is also a tiny bit of tick tick, searched it online and apparently that is usually from the purgers and is normal mechanically.
Thanks!
What about cam adjusters and time chin issues are they common because im having them and need to be checked
Any timing or cylinder head issues?
Do you have to drop the motor to replace the intake manifold gaskets?
I am put a can of Liqui Moly Mos 2 every oil change. is this OK for M176 Engine? Thanks
Thank you for this valuable video. I have a question for you. I want to buy a Mercedes AMG GT 63, model 2022, with an M177 engine. Do you advise me to buy it or not? Thank you in advance.
What's the r+r hours for the oil separators?
Do yalls Hot Vee engines consume oil?
Great video, I'm having the issue of oil on one spark plug and coil pack! Does this engine have a Mercedes Spark Plug Tube Seal inside the valve cover? There are no leaks on the ground or in any of the other spark plugs or coils @603benztech
Valve covers are sealed with sealant , there are no seals
@@603benztech thank you, so no gaskets or seals only a sealant?
Another apparently common problem: camshaft adjusters and camshaft position sensors leaking oil through the electrical connectors. Oil seeps through the wiring harness over time eventually getting to the computer etc. Just checked my camshaft position sensor connector (50k miles) and there's a little puddle of oil in it and oil on the connector.
Yeag we will be making a good video about that when one comes in
would all be small problems if it weren't so complicated and hard to work on
Does these same issues appy to the M178?
Yes for sure.
@@Fastpetrols Too bad. Part of me really admires the engineering, but the other part of me says avoid that German over-engineering.
Loving your channel Mike, but please start mentioning the mileage of the vehicles that you’re working on when it pertains to specific issues/services that you’re performing, so that viewers can get a better idea of when these maintenance items are due.
Thank you! and this vehicle had 70k
Having spent the last few weekends under the hood of an M278, seeing this video has made me loose faith in Mercedes altogether.
How did they manage to make it have MORE hoses, wires and sensors AND be harder to work on?
I miss my M113K
I have big problem with this engine with timing,3th time is engine out covers down,new 4x camadjusters,2x timing chain,2x tensioner,1x camshaft bank 2 exhaust,today again start new oil filter 2x, and again mistake on bank 2 intake and exhaust camshaft,everything set up on timing 40 and on 53 plates are excelent,timing was set up by original tools,iam doing all mercedes-benz motors 13,5 years and i never had mistake like this after repairing the engine,when somebody know please hepl
"I'm gonna mention 2 or 3 things I've seen with these engines.."
*lists 7 or 8 things
Misfires bruh, misfires .. You forgot to mention those .. Tons of em bugged with this problem. Bad coils, bad sparks, very common issue and and those coilpacks are often on weeks long backorder.
Warranty unfortunately won’t pay you to drop it. Or will it🤔This is my 3rd time within 3 months opening/ resealing valve covers replacing camshafts, sprockets, even a cylinder head all on the same lemon. Needless to say I’ve almost quit so many times because of this engine alone
What was the customer complaint
I've worked on Mercedes-Benz vehicles for 23 years. I worked at the dealer from 2001-2010. These newer V8s are junk compared to m119/m113/m273. No more 63 anything for me. Even the m113k is starting to show it's age with the o-rings disintegrating behind the front timing cover causing oil and coolant to mix and o-rings failing down by the oil pump causing starvation. 20+ hours for motor mounts? Reminds me of the w220 S65 labor times. Plastic Intake manifolds is giving off bmw vibes. I do not recommend any mercedes newer than 2011.
Amg now along with nmw s58 engines are the most reliable vars on roads today
Lol incorrect
♠️GOOD INFO! TELL US THE TYPICAL MILEAGE TO EXPECT THESE REPAIRS AT.. and if it’s from normal , lack of use for garage queens, or if it’s from extreme abuse .
Car has 189 000km is in W222,of course new termostat rear seal,breaders 2x
Repair start with mistake on bank 1 intake camadjuster was bad
Covered until 150000 or till 2035
Thank you 🙌🏾
@@603benztechgreat information! I assume it’s normal to get extremely hot on a summer day in Florida? I don’t drive it too hard but the engine remains hot for a while…
15yrs or 150k miles for thermostat coverage.
This engine is a supercar engine for supercar guys with supercars budgets 😅
24 hrs * 300 labor rate = 7200 just for two engine mounts.
Sounds like dealer rates 😢
@@603benztechjust a random question, would you replace your engine mount with a non mercedes dealer? the engine have to come apart.
@@ceacaralex3994 use Mercedes parts and have an independent shop install. One you can trust
With AMG it's not so much whether you can afford the car, but whether you can afford the maintenance. Typical German over-engineering.
