Why Engine Bearings Fail: Root Causes, Oil Analysis & Wear
Why do engine bearings fail—and what can the wear patterns inside an engine tell you about the real root cause? In this highly technical episode of EPARTRADE Race Industry Now, Dustin Kull, Account Manager – Racing and Aftermarket at Daido Metal, and Lake Speed, Jr., Tribologist and The Motor Oil Geek, break down advanced engine failure analysis and the science behind bearing wear, lubrication and oil-film failure.The discussion goes deep into:• How bearing wear patterns can reveal what is happening inside an engine• Oil-film thickness, viscosity, bearing clearance, speed and load• Why microscopic contamination can cause major bearing damage• Crankshaft deflection, housing deformation and edge loading• How detonation can produce bearing damage that looks like an oiling problem• Using piston rings and other engine components to confirm a failure diagnosis• Oil aeration, windage and oil-pressure loss at high RPM• Bearing material selection and crankshaft dynamics• SEM analysis of embedded debris and identifying contamination sources• Used-oil analysis as a diagnostic tool• Why oil operating temperature matters• Why simply increasing oil pressure, clearance or viscosity may not solve the real problemFor race engine builders, performance engine shops, racers and engineers, this session demonstrates why effective engine failure analysis requires looking beyond the damaged component and understanding the complete lubrication and mechanical system.Featuring:Dustin Kull — Account Manager – Racing and Aftermarket, Daido MetalLake Speed, Jr. — Tribologist, The Motor Oil GeekHosted by Brad Gillie — SiriusXM, Ch. 90, Late ShiftAdvanced Engine Failure Analysis: Diagnosing Root Causes & Wear Mechanisms with Daido Metal and The Motor Oil GeekPresented by ARP, Inc., PEAK, Fifth Third Bank Motorsports, Ferrea Racing Components, CTech Manufacturing, & Race-Fan.EPARTRADE Race Industry Now — Episode 634#EngineBuilding #EngineFailure #EngineBearings #OilAnalysis #Tribology #RaceEngines #Motorsports #DaidoMetal
