Having read through all these posts with very interesting info.
I am a bit puzzled. I have seen quite a few M117's with totally worn out engines loosing compression due to worn out cylinder walls and burning oil like crazy and nothing is metnioned about that. These were W126 380SEL's and 420SEL's up into the last year early 90's models. What exactely, if any, are the differences in the production of the blocks for the aluminum M117's and the later M119's? Do both have silicon liners/sleeves or is that just the M119 and the M117 were merely honed, no liners? I was under the impression that the M119 is by far the better engine and not only in the performance department.
Thanks for the info in advance.
