Was This 2019 GMC Sierra 5.3L L84 Engine DESTROYED In OR By Accident? ONLY 107,452 Miles!

For parts go to www.Importapart.com or email us at [email protected] Today we tear down the 5.3L L84 V8 Engine from a 2019 GMC Sierra that was in a pretty serious accident. Normally in wrecks like this, the engine survives with minimal damage but in this case, the engine was RUINED! The engine comes from a truck bought at the Copart salvage auction that was intended to be resold but once the truck was dismantled, some major block damage was found and the engine found its way into my shop for a proper autopsy. So what happened here? Did the engine fail during the wreck? Did the engine fail due to circumstances following the accident? Either way, the results were pretty wild as this type of failure while not rare, usually results in slightly less crazy damage. My name is Eric and I own and run Importapart, a full service used auto parts business. Part of our model includes buying blown up and failed engines with the intent to teardown and salvage the good parts while recycling the rest. We do not rebuild engines, merely supply parts to people who do. 00:00 Intro 03:45 Removing the spark plugs and.... DRAINING THE OIL!?
