Thanks for keeping this thread updated with great pics. If the coating is twice as hard then there should be wear on the Pistons too, more so than on the bore. But as you said you're probably fine with just leaving as is.
I think you're on the right track. You never touched the rings so in theory they should be sealed to the cylinders still. A bit of coolant I doubt would wash the oil away, it would probably be vaporized by combustion temps before that would happen. Plus oil and coolant aren't soluble.
Do you have any vertical scoring in the cylinder walls?
Mercedes won't reapply that coating, they just order a new block. You could put new rings on it, but then you have to pull the engine. I think you're good to throw it back together and drive it.

Thanks TIR, I appreciate it. If anyone is tired of seeing updates on this please, feel free to tell me, I'll stop. I guess at this point I'm trying to let others know what to expect if they encounter a similar situation. I obviously made a boo boo by trying to band aid a situation that needed full blown open heart surgery. At this point, I want to see what effect, if any, running it with the coolant leaking into the cylinder will have on the cylinder walls themselves. If I experience blue smoke once this is all said and done, or God forbid, catastrophic failure, then hopefully others can benefit from my experience. I talked to one member here privately that had done several of these and he assured me that he never touched cylinder walls when replacing these gaskets and he never had any problems after a gasket change. And several of those engines were leaking coolant when they came in. So, hopefully, all this work is not in vein.

Agreed Merc63, on all accounts. And no, I did not see any scoring of any kind on the side I've done. I should have the other side off tonight and we'll see what that looks like.

Keep the updates coming man, lot of great information to be had from this.
And of all the cases of a broken headbolt with coolant leaking into the cylinders, or on other cars with a blown head gasket, very few have needed a whole new engine block (when caught in time like you). I think you're good to go.

Important to note, I forgot to say something earlier, but I got my dial bore gauge out and had no more 0.001" (of which my gauge is good to within 0.0005" +/- ) difference between each cylinder in the right bank, so hopefully that means I'm good to go.
Here's the driver's side, looked MUCH better than the passenger side, but as a result, it was a B***H to get off. That head was stuck to the block better than any composite gasket I've ever had to break loose. Unfortunately, I do believe I disturbed what was a perfectly good seal. Let's hope the new one seals just as well.
Well gents, here she is, all back together and running like a raped ape again. Definitely idles smoother, so we'll see what the long term results are. Thanks for all the help and info along the way guys, really appreciate it.

fantastic! Like the dash of red in the engine bay. It should also have tamer and quieter cold starts unfortunately. Hope keeps staying smooth...nice job
