Let me guess: you like the LNE fix, so anything else is inferior and wrong? Yeah  |
You're clearly not an engineer, and don't follow this forum too closely. Removing material from the outside of a shaft is the absolute worst place to take it. Not only will it weaken the shaft but worse it will promote cracking. A hole down the axis will have negligible effect on the shaft torsional strength. I independently came up with this oiling scheme and posted it to this forum perhaps 18 months ago complete with power point sketches. I did not go with LN in my engine, but vented the IMS shaft to eliminate pressure across the IMS bearing to prevent engine oil being forced through the IMSB and washing out the grease. How do you think the oil always ends up inside the shaft? There is only one path, and only one substantial motive force to put it there.
