Joe, Thanks a million. I was just about to PM you in regards to that.

Checked out vehicle and it is pretty clean and minor stone chips on the hood that have been covered up with touch up paint. If price is right then I might get it despite still being on the bad list and hope for the best. Eventually getting the Weistac bolts

bhamg, Theory says corrosion needs two (at least) dissimilar elements and electrolyte. Coolant is primarily developed for aluminum/iron and I have seen it work well in many engines. The worst I saw was an Audi which had a thermostat housing heavily eaten away. But as I said to merc, WTF is the explanation here? I would think alloy steel bolts would be less prone to rust than cast iron, e.g. water pump impellers and iron blocks .

Someone 'splain it to me in terms like...the coolant additives somehow have been depleted at the head bolt interface and water (electrolyte) is separated from solution and attacking iron in the classic manner. There must be a chemist or metallurgist out there... Please don't make me try to research on line...

I would like failure analysis. Wouldn't you? regards , motoman

^ Agreed motoman. Somebody please step up. IIRC there is a packet of additives embedded in the cooling system designed to maintain a constant level of protection by replenishing
additives that are used up over time.

Anyone know if and when they changed the valve lifter buckets on the M156 motor to the M159 (SLS) ones?

According to the parts manual... the old M156 part number is now superseded by the SLS M159 part number....
Anyone know the answer to this? Did MB ever change the camshaft adjusters on M156 production?

Exclamation 2009 C63 amg Headbolts

Hello everyone,

I am in the purchasing process of a 2009 C63 and have learned of these headbolt failures. This car has 52k original miles and the seller is asking $22,500.
Is this a risky purchase?
Are there any tell tell signs of the failing headbolt before it fails?
I have seen the weistec replacement bolts.
Does anyone think that Mercedes would possibly good will this repair since its a well known failure?
I learned of the active recall on the airbags.
How common are the failures to the valves?

Thanks in advance for any input.

VIN: WDDG77XX9F26829

-Ronnie

Hi Joe, So I have just found this head bolt issue after all these years, nothing has happened yet and it shows no sign of wear and tear.

Could you check VIN WDDGF77X79F209471

As I am struggling to find any place to find if its affected or not. Probably is but about time it starts getting tuned.

Not 100% accurate.

Mine is November 2010 build, and I have he new bolts. I confirmed that last week when I had my cracked valve cover replaced

Short of taking the valve covers off, I think the best to go on is after engine 60658 & if it has the black plastic valve covers.

It is accurate. Post your VIN. US car? If no, then it may not be 2010.

Countries outside US don't conform to US model year process.

Fair point, but pardon my ignorance, maybe the next question will be a dumb one but ill ask it anyway...


Whist my car is Australian, why would that even matter? They are all built in Germany, so the build date & engine number on the data-card are given at the AMG Factory in Germany. Therefor the US Model year process would be the same? The only date that would change would be the "Delivery Date"??

We use the US model years to define if the car is in the affected range. If a US car is 2010 and older, it's always affected. Some early 2011s are as well. This is why one must check the VIN in the database to ascertain the engine number. Yes, the engines are built in Germany, and they can go into cars of all countries. But again, here in the US we know that any car in model year 2010 or older is affected, without having to look up the data. You're car was right in that spot where it crossed over into 2011 model year even though you point out it was made in 2010.

Hi new member here.

Any chance my VIN could be checked if my car is affected as well? WDD2042772F564429

I believe my engine number ending in 62868 is outside the range but would like to be sure.
