5 CYLINDER TEARDOWN! How Did Someone Ruin One Of VW's MOST RELIABLE Engines?

For parts email us at Sales@importapart.com or go to www.Importapart.com Today we have a very special treat for everyone. An engine that has been requested since the early days of the channel. This is the 2.5L 5-cylinder from a 2011 VW Jetta. These engines are incredibly robust and have a great exhaust sound. I've been looking for a bad one to teardown for YEARS. The wait is over. I don't have details on this engine, like miles but I can tell what its from based on the parts and date code stamps. It turns out, someone has managed to RUIN ONE! But how? In this video we try to figure that out! The 2.5L Volkswagen 5 cylinder was found in the Jetta, Beetle, Golf. This variant makes 170hp and 177lbft of torque. They run strong especially when paired with a manual transmission. The ran this engine through the 2014 Model year. Why am I doing this? My name is Eric and I own and run Importapart, a full service auto recycler. Part of our model includes buying and dismantling blown up and core engines to salvage the good parts from, recycle the rest. 00:00 Summary 02:58 Looking at the intake ports, its been WET 03:50 Unbolting the valve cover 04:17 First look at the valve train.
