My '92 300SD with 243,391 miles on it smokes escessively and uses LOTS of oil. After shutdown and sitting for awhile it belches alot of smoke on startup. I suspect valve guides/seals are worn enough to allow oil to enter cylinders and cause excessive smoke at startup. Woud a rebuild head solve problem or are wornrings also a probability? Would appreciate any comments.
