Today we have an often requested Volvo B4204T27 Twin-Charged 2.0L Out of a 2016 Volvo XC90. This 2.0L, Direct injected, supercharged and turbocharged 4 cylinder pumps out an impressive 316hp but that power level comes at a price; Reliability. These engines are NOT known to go the distance and have a few different failure points which some have been remedied, some have not.
This particular engine has 125K miles and has an excellent service history with oil changes every 3-4,000 miles and with the exception of tires, has only been serviced at a Volvo dealer. So how exactly did this engine fail when things were "done right?" That's what this video shows as we tear it completely down and find both the damage and the culprit!
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 up and core engines. We dismantle these suspected bad engines to salvage and resell the good parts while recycling the rest. We do not rebuild engines, merely supply parts to those who do.
