true but with 200k he Drives 16k+ yearly, and he had a flame tune so he must have spiritedly drove it, I just think these motors got a bad wrap, of course many where affected but maybe not all we think, as another member stated many have 100k+ stock headbolts and mods and there cars run better than new amg’s

That’s why I always encourage people to buy high mileage C63s. Odds are that if the car has mileage similar to ours the headbolts will most likely not ever fail. But if the car has anywhere from 20-100k, that to me is a toss up and the headbolts can go at any moment. Everyone I know that has had headbolts failure they have had low mileage cars.

They will all need replaced at some point but most are not a catastrophic event. I've seen a 211 e63 with 248k and original head bolts. Changed them with a motor tear down / reseal, however they had not failed yet. You are much more likely to have lifter / cam issues or adjuster issues and should just change them while you're in there.

Yeah they will need to be replaced at some point if your not on top of your oil changes and do not keep an eye on the level. As far as the headbolts go. If your car has high mileage I wouldn’t change the bolts unless you plan on taking the heads off and refreshing everything. I’ve seen lower mileage m156 cars with noisy valve train and rattling can adjusters, but mine even at 200k is silence as can be.

oil changes are everything. 10k is too long unless it's all long distance easy high way mileage.

Hey everyone. I have a '10 C63 AMG, 127k miles stock headbolts. No major issues at all- but today I started the car and got the dreaded "low coolant" message. Checked coolant and it was a little low- a little dirty but no oil. Oil was clean as well. I've had no symptoms of headbolts failing as drove it yesterday and was totally fine. No leaks under the car, etc. It's been a bit cold where I live so could that be it because I let the car run a little bit and the message went away once engine got up to temp. Took for a quick spin around the block and everything seemed normal- was too afraid to drive it farther. Am I overreacting? I'm a rookie when it comes to AMG's so please take it easy on me haha. Thanks

You can take a chance and monitor closely. I took pictures every day of my coolant and it was ever so slowly going but nothing on the ground. It must have been burning up.
I took it in just in time. A few bolts were about to go.
If it fails, the repairs will equal your book value.
did you just get it?

It is probable that you don’t have an head-bolt issue, but still could have a coolant leak. That would go unnoticed while the engine is cold, as this happen to me on my E63. Their was a tiny hole in the radiator, you already know the properties of expansion and contraction in the cold. Only when the engine was warm/hot would it leak. Have your shop do a pressure test, to absolutely rule out head bolt issues. If you have a coolant leak, a pressure test will find it as your car will not hold pressure. This is the easiest and cheapest diagnostic method.

Thanks for all the fast responses guys i really appreciate it. Got the car 2 months ago- had some work done on it by a good indy shop (end link stabilizers, transmission service) and only put 300 miles on since so this kinda sucks haha. Will go ahead and take it into the shop as y'all are saying. Problem is the shop is 30 miles from my house. If i top it up will it make it there? Coolant currently ~1 inch below black marker. Read all sorts of nightmares about headbolts going within minutes

Stop reading all the horror stories...you’ll give yourself an aneurysm. Top off your engine coolant, and head to the shop. Has your car indicated a low coolant CEL. If not, put the extra coolant in the trunk and make the drive. And stop worrying, until you get an accurate diagnosis of the issue.

lol you're right. Only thing I got was a message saying "check coolant level" on the dash and then it went away after engine was warm. Super busy this week but will take it down to the shop early next week. Will keep you all updated- thanks so much once again

130K+ miles on the clock with the only big ticket items being Transmission fluid ($1200 from dealership) and an intake manifold that I didn’t need (purge valve connector piece just needed reseated)
I do oil every 4K miles 5W40 liqui moly during the summer and Mobil one 0W40 during the winter with liqui moly additives

A transmission service doesn’t cost $1200 to do, find yourself an independent MB shop, and have them do it. I pay roughly $450 for my shop to perform a flush with them buying all the supplies. I just bought the filter kit and fluids myself, so this time I will just pay for labor only. You can go onto any website that supplies parts for Mercedes and order everything (filter kit and fluids).

Well you will just have to bite the bullet or find some other shop and make the drive.

The service is a transmission fluid change. (NOT a flush) This entails draining the transmission oil, dropping pan, replacing filter and pan gasket, installing pan, adding fluid. It's 2 hours of labor max.
At two different independent shops in the Washington DC area, I paid <$400.

Those price quotes are ludicrous. Parts are ~$100 (https://www.fcpeuro.com/products/mer...em-7229erlysk1)

Hey everyone- unfortunately I have a terrible update. I drove the car down to the shop, everything felt totally fine. Mechanic said the coolant and oil has mixed, with a whole host of other stuff which I need the invoice to confirm to y'all, but basically the dreaded headbolts issue is here. I'm honestly surprised at how bad luck this is since I've only driven the car for 300 miles and there were no warning signs. The shop is good, with lots of other high end vehicles as clients. Trying to be positive- as now I can finally drive headache free and with upgraded SLS parts. Ill send the invoice once I get it but based off the phone call: new headbolts, lifters, resurfacing of cylinder heads, head gaskets. He said based on past experiences it will run me in the range of $3000. Is that a fair price? Thanks everyone.
