Yup.on that main oil pipe thread someone posed the question if the left side turbo failures that we have heard a few cases of are connected to this oil pipe failure. when a turbo fails it is always the left one. the oil pipes are not identical. The left one reaches farther I think and has flex mesh hose with it from what I recall reading. also the heat exposure to the left pipe is greater also from I recall reading. actual hands on experienced commentary is invited.
