Today we tear into the engine from 2020 Chevrolet Malibu. This is the base, 1.5L Turbo "LFV" engine and its only gone 98,000 miles before it was replaced. I was able to source the last 8 of the VIN from the block and call the dealer to get the rest of the VIN, and run a Carfax to get its mileage, and maintenance history which dare I say, was sporadic at best. The early versions of these engines suffered from LSPI and melting pistons. This was allegedly corrected for the 2018 MY. So what happened to this in just 98K that required replacement? Lets tear it down to find out!
These engines produce 163hp and 184lb ft of torque, and ran 2016-2022, exclusive to the Malibu in North America, but offered in many different vehicles world wide.
Why am I doing this? My name is Eric and I own Importapart. A full service auto dismantler. Part of our model includes dismantling blown up, failed and otherwise bad engines to salvage the good parts. We do not rebuild engines, merely supply parts to those who do!
