Today we are tearing down an engine that MANY people have been requesting for a long time. A Volvo 5-cylinder! This is the 2.5L B5254T5 out of a 2012 Volvo S60 T5. I don't know miles as I couldn't read the entire vin due to the extreme corrosion on the block. This engine was SIEZED, but was that why it was replaced? if it wasn't, what was the original reason?
The Volvo modular engines have been around for a long time, this one makes 247hp and 266lbft of torque, and was only around for a few years. The design of these engines change throughout the generations but the overall architecture remains the same.
Every week I teardown a new engine that has failed in some way in an attempt to figure out why it failed, what was the initial cause, and what parts survived. Here are a few of my favorites over the years:
8.0L Dodge Ram V10 WORST ONE EVER    • 8 LITERS OF DESTRUCTION! Dodge Ram V10 Eng...  
Volkwagen 2.5L Inline 5    • 5 CYLINDER TEARDOWN! How Did Someone Ruin ...  
560hp BMW M5 V8 Teardown    • LOCKED UP 560HP BMW M5 S63Tu Hot-V Turbo V...  
3.0L Duramax Diesel DESTROYED at 45K miles    • WARRANTY REJECTED!? 2020 Silverado 1500 3....  

Why am I doing this? My name is Eric and I own and run Importapart, a full service auto salvage business. Part of our model includes buying and dismantling blown and core engines. We salvage the good parts and recycle the rest. We don't rebuild engines, merely supply parts to those who do!
