I'm thinking about buying a 1990 350 SDL. It has 360,000 miles on it and is the original engine. I'm new to Mercedes so I'm trying to learn as much as I can about this "rod bending" issue before I take the plunge. I hope some of you here can point me in the right direction. I've read that if it hasn't bent any rods to this point it should be "OK", correct or not? Does this engine block use cylinder liners or not? I've also read mixed reviews of the head on the car. Can someone give me the part numbers for the preferred & not preferred engine, head, transmission or any other vital part. A side question....have "new" rods solved the bending problem and did anyone ever solve the mystery?

Thanks, Dwayne
