Engine bearing failures are rarely as simple as choosing the wrong oil, running too little oil pressure or setting the wrong bearing clearance. In a high-performance engine, lubrication, bearing geometry, crankshaft motion, contamination, temperature, load and component deformation operate as an interconnected system—and diagnosing a failure requires understanding how those variables interact.

That was the central theme of EPARTRADE’s latest Race Industry Now technical webinar, “Advanced Engine Failure Analysis: Diagnosing Root Causes & Wear Mechanisms with Daido Metal and The Motor Oil Geek,” featuring Dustin Kull, Account Manager – Racing and Aftermarket at Daido Metal, and Lake Speed, Jr., Tribologist and The Motor Oil Geek. The session was hosted by Brad Gillie of SiriusXM, Channel 90, Late Shift.
