Why this Toyota 2GR Engine Failed

Подробнее о видео

Here's a look inside a Lexus ES350's engine that failed.

The engine had 213,000km and had the rear intake bank camshaft VVT gear actuator bolts back out. As a result, the camshaft could no longer hold timing, causing the pistons and valves to collide and bend.

Toyota and Lexus had a recall on these engines for the camshaft bolts backing out, however that was for the 2GRFSE versions found in the Lexus IS350 and GS350.

This 2GRFE engine had difficulty starting on three cylinders and sounded horrible. More on that here:



Many earlier 2GR engines did have many common issues exhibited by this 2007 model including the water pump failing, the front timing cover leaking, and the VVT lines being made of fragile rubber instead of metal. Thus it is best to purchase a model with these issues addressed later in the generation.
