My understanding of my readings about this engine is that not every one of them is a "rod bender" and some actually do last a long life without exhibiting the failure. If yours shows no signs of trouble at this point why would you worry? There's nothing you can do to prevent it except perhaps driving a little more conservatively to reduce the stresses on the connecting rods and hope for the best. If you start to see symptoms of impending failure (ie rapid oil consumption) then you'll know you have to deal with it, but given the number of these cars out there with 200K+ on them I think having made it to 127K you may have one of the good ones. Also, I heard that MB was replacing the short blocks which started failing in these cars...how do you know your car doesn't have a new, improved block in it? Are you the original owner?
