|  1990 350SDL rough idle 
			
			I look forward to reading all of your collective input and knowledge so that I may garner a more complete knowledge of my current vehicles. I have lurked on this list for only a few day however, I have read the archives. Introductions completed I have a few questions to pose to you the experts. My 350 has a rough idle, and shutters if I run the rpm to 1000 to 1500 then pulled my foot off rapidly. This quickly recovers, but is annoying. I am not yet sure of what the oil consumption rate is however, the old owner said " it does use oil between changes". It is my fear that I will be the victim of the sad 350 story. Not being good at being a victim, I seek your collective advice as to which is the best way to proceed. My thoughts are to rebuild the engine. I understand from archived data that the number one rod tends to bend. There was also an illusory post as to modified rods available. I further understand, that Mercedes has a higher tensile strength head bolts and an improved head gasket, both of which I have obtained part numbers for. Does anyone know about these improved/modified rods. Thank you and hopefully I may be able to someday answer some questions that some of you may have.
