BMW M54 Engine Teardown - Dissecting A Windowed Block After A Money Shift

►The last two decades' worth of BMW straight-six engines is a relatively tough bunch. The M50, M52, and M54 have powered countless E36 and E46 grassroots racers through series across the globe and have been pretty successful thanks to their generally solid power, accessibility, and reliability. But like any race engine, they aren't without their rare and spectacular failures. Our Associate Video Editor Stephen Coppola and his Spec E46 were victims of one of those fluke incidents, leaving the pairing with a very ventilated engine block.
But every failure is a new opportunity. The Spec E46 will be back next season with a new engine, and the old engine is getting dismantled for science. Watch as Stephen and FCP Euro BMW Expert Gareth Foley tear down the blown-up M54B30 to find out where it all went wrong.
