Here's how the Toyota 3.0L V6 Engine Became a Success

In this video the 1MZ-FE 3.0L V6 engine is torn down and analyzed. This engine is known for its longevity, reliability and smooth operation, albeit a lack of power according to modern standards. The 1MZ-FE engine was overbuilt for reliability and the ability to take forced induction from the available TRD Supercharger at the time. The 1MZ-FE was produced from 1994-2006, used in popular applications like the Toyota Avalon, Sienna, Highlander, Solara and Camry, as well as the Lexus ES300 and RX300. The engine in this video is from a 2003.5 Toyota Camry V6 with approximately 170,000km, in its latest revision with variable valve timing and a drive-by-wire throttle body, negating the presence of an EGR system. In this teardown, we find the engine is comprised of a plastic intake manifold with an acoustic air induction system, metal valve covers, aluminum alloy heads, block and upper oil pan, in addition to the the stamped steel lower oil pan. It has dual overhead camshafts driven by a timing belt and variable valve timing on the intake side. The block has a semi-open deck design and cross-bolted main bearings for the crankshaft with two pairs of thrust bearings to ensure longevity, as well as a uniquely balanced crankshaft for smoothness. Some of the weaker spots on this engine included engine oil gelling due to an under-designed PCV system and long oil change intervals, valve cover leaks, faulty knock sensors and harnesses and a difficult to access power steering pump.
