I remembering hearing in the early 1990s that the racing fluid dampeners, all brands, would break crankshaft when the motors were revved up above 5000 RPM with the outside air temps near freezing if the owner didn't let the motor run for at least 5 to 8 minutes to warm the fluid up in the dampeners. Back then we did not have the communications like we have today so maybe that rumors was just that, a made up rumor
Big diesel engines have used them for a long, long time in all kinds of applications with no big failures on their cranks that have been reported in all kinds of climates and job applications
