[MBZ] Carbon Deposits

[dave walton]

Thanks for all the wonderful insight about wheel bearings. I consider
a little dressing down by Marshall to be an honor and will endure
embarrassment to get the good info.

I have about 1/2" of carbon deposits on the inside top rim of the
cylinder walls. How should I remove it? Would prefer not to grind off
any metal in the process. Wiping with kerosene got the easy stuff off.
I'm thinking Easy-Off oven cleaner or something

Thanks

Tried carb cleaner?  I seem to recall that's what I used on the VW
diesel I did a head gasket job on.

How about a ridge reamer?
I think you can set that and be careful so you don't take any metal off.

Okay, I gotta admit, this is the one argument I don't understand.

I'm not saying I think the wheel bearings should be set without a dial
indicator.  If Mercedes says that's how you get the best life out of
them. I'm inclined to believe them.

I just don't understand how setting the wheel bearings properly is
supposed to help with steering feel.  These aren't rack-and-pinion
steering cars.  They're pitman arm, and like every other pitman arm car
I've driven they have a good inch or two of play at the steering wheel
rim.  It's the nature of the beast, and it's because the pitman arm
design amplifies any slop in the steering box and tie rods.  It doesn't
matter how tightly you adjust the bearings, the car is still going to
have a big dead spot in the center.  It's never going to be "precise"
like a rack-and-pinion car.

Am I missing something subtle here?

( Sigh )   go get one of those little pads with all the rubber fingers on
them. I use a 1/4 angle grinder ( air ) to run it. They come in three
different grades - yellow, white and green. Green would probably work best
on cast iron.

These things are great for cleaning all sorts of castings and surface areas.
They won't gouge or nick like a grinding disc or scraper. And they're really
fast.

My S350 started burning oil way bad all of a sudden. Turns out the head 
gasket blew in front of the #1 cylinder. A friend is coming over tomorrow 
with a dial bore gauge so I can see if the cylinders are elongated - or I 
guess I should say; to see how badly the cylinders are elongated, since this 
in the infamous rodbender engine. It has 182k miles and I can still see the 
crosshatch pattern on the cylinder walls, so I'm hoping for the best...

Here are some photos if you are interested:

Great pictures Dave, for a terrible event! Here's hoping it's not as
bad as it could be.

Re: [MBZ] Carbon Deposits

This car suites me well (big, heavy, and underpowered). I hope to be driving 
it for a while longer. My understanding is that the 603.971 3.5L was made 
from a modified 603.961 3.0L. Does anyone know if the 3.0L will easily 
replace a 3.5L in an S350?

Thanks
