Maybe, but given time I'm willing to bet a small amount of cheese this will happen eventually. The bolts will continue to corrode weakening that already small sectionalism area in the bolt head.
Why introduce coolant into the lubrication system if you don't have to?
Or just hold out until there's a recall 5yrs from now
thanks for the help jason.
out of curiosity since from your sig you have a 2010 C63 which would be in the affected range.
have you replaced the HB? if yes, how much and did you just replace the HB or lifters and cams as well?
spoke to the shop, was told the anything related to the codes would be fixed and cleared prior to the sale.
my only question is, if they were to clear the code using the OBDII and then after the sale i drove it for 100km and the light came back on, do i have any recourse?
cause if they simply reset it using the OBDII and send me along... i would have no clue til the CEL came back on.
I had a code for one of banks being lean. It might have been the same code. My intake manifold gasket was leaking. I replaced it on my own (pcv valve, gaskets and bolts) for relatively cheap. I'd have to look at my records to see the actual price. Intake manifold fasket failures aren't uncommon with the earlier cars.
just got back from looking the car.
car itself is good shape however pulled 2 codes from the car:
P0300 - random misfire detected (thinking maybe ignition coils need to be replaced)
P0171 - system to lean (bank 1) (emissions related i would think)
need to do some research.
Are these stored codes or current? If stored how long ago? Maybe IM gasket as chrisridebike8 mentioned. Misfire and lean bank could be an air leak after the MAF but if it happened in the past and was fixed don't worry about it. Swapping out the IM gasket is 30bucks in parts and a few beers work.

or would it be the third picture (obviously you can see all the HB at this point).

With the valve cover removed you can see the HBs. You don't need to yank the cams to see what bolts you have. Just the valve cover.
removing the valve cover is the first picture in post #2? (as per pic above).
isn't that a 15 minute job? how come i keep reading/seeing people say it's a 1.5-2 hour job?
both codes are current and would need to be addressed prior to sale. only thing is they could easily just reset the CEL using the obd reading and send me on my way.
It's below VMR so depending on the actual condition I'd say it's reasonable.
Budget for HBs and front lower control arms though. Maybe a new IM if the previous owners use ethanol fules.
would you also recommend getting the valve buckets done when the HB are being done, is this a necessity, from what i read, not sure these tend to fail alot.
ok, i'll get a quote and see the pricing on those items as well.
it looks like to me even after purchasing the car i'd be looking at a $5k bill on top of the vehicle to do the following:
1) head bolts, cam shaft bolts, valve cover gaskets.
2) valve buckets (not sure whether it's necessary)
3) maintenance items (coolant, oil, rear diff fluid, brake fluid, spark plugs)
4) engine & transmission mounts (i feel like this can wait until symptons arise)
5) intake manifold
6) front lower control arms
anything else? how does my list look, anything you'd remove/add?

thanks jason, very much appreciate your help.
the more research i do and look into the C63... for such an expensive car (when purchased new) it sure does have alot of problems and faulty parts.
haha, thanks for the offer.
knowing all the issues the pre 2011 C63's have, would you still buy one?
i mean for an expensive performance car you wouldn't think you would have to shell out $10,000+ in repairs from the head bolts, intake manifold, engine/tranny mounts, valve buckets... i'm sure there are other things i still have yet to read about.
The HB preventative repair cost is low.
Front LCA can be checked and negotiated into the price if they're bad.
Valve buckets are likely fine
IM is likely fine.
I forgot to mention the ESP module lol. That one is another 2k if you have issues with it.

It's a 7+ year old 500hp car for dirt cheap.
sorry, noob question coming but i was under the impression there were only 4 control arms (front passenger and drive and rear passenger and driver). but looking at parts on rockauto, theres front lower & upper.
is it only the lower that needs replacing? what about the upper?
The "technically" upper arm I think is called a torque strut by MB or something like that. Other suppliers (lots of them) call it a front lower, but that one is not the problem child.
