Another DEAD Hyundai 2.4L Theta II Engine. Will every single one of these FAIL?

For parts go to www.Importapart.com or email us at [email protected] Like disastrous engine teardowns? I post a new video every Saturday evening and have done so over the last 4 years! Here are some of my favorites: 1. 8.0L Dodge Ram V10, the worst one we've EVER SEEN    • 8 LITERS OF DESTRUCTION! Dodge Ram V1...   2. Hyundai/Kia 3.3L Lambda V6 with few survivors    • Taking "Blown Up Engine" To A New Lev...   3. Honda J35 Destruction    • Obliterated Honda Accord J35 V6 Teard...   4. Audi S6 5.2L V10 Massive damage    • DEVASTATED Audi S6 5.2L V10 Engine Te...   Today we have another suspected failed 2.4L Theta II engine on the teardown stand. This engine has lived a double life, first being in a car totaled in 2020 with 51K miles, then reinstalled into an "unknown" car for unknown mileage for roughly 3.5-4 years before ultimately failing. So I don't know the exact miles, but it's clear this engine wasn't long for this world by the condition of certain parts. From this teardown and teardowns past, it's clear to me these engines fail not just from neglect and abuse, but poorly chosen materials, machining error, or overall design. The Theta II came out in 2011 and are direct injected, close to 200hp, and offered in a host of Kia and Hyundai vehicles. From the very beginning these engines started to fail to the point that NHTSA got involved, and now there is a nation-wide campaign to replace defective engines IF the ECM reprogram has been done prior to engine failure. The reprogram changes the knock sensor parameters to control throttle and load in the event of rod bearing failure, to limit the chances of a rod exiting the block and spraying hot oil on the exhaust potentially causing a fire. Dealerships across the country are backed up replacing the engines and used engines still fetch $2500-3500 which is a lot compared to the value of some of these vehicles. Why am I doing this? My name is Eric and I own and run Importapart, a full service auto dismantling business. part of our model includes buying blown up and core engines to dismantle for parts. We teardown engines to salvage and resell the good parts, while recycling the rest. We don't rebuild engines, merely supply parts to those who do. 00:00 Intro 05:12 pulling the spark plugs to inspect. WATER 06:07 removing the intake manifold, stop stealing my socket! 08:01 Taking a look down the intake ports at the condition of the valves, GDI= Gross Dingy Intake 09:35 unbolting the High pressure fuel pump 10:00 Zipping out the valve cover bolts 10:55 First look inside this engine... not terrible, not great, but not the worst 11:42 Ticking the timing cover, removing the motor mount bracket, water pump pulley and harmonic balancer 12:41 Forcibly prying the timing cover off and inspecting the timing system 13:48 Peeling off the timing chain, rails and tensioner 14:50 unbolting the thermostat housing and averting a mess on the new floor 16:21 Cracking the cam caps loose and removing cams to inspect valve train 18:35 Cracking the headbolts loose. VIOLENCE! 20:05 Lifting the cylinder to reveal the condition of the cylinders... WATER! 20:47 SCIENCE 21:53 turning the engine over, feels bad man 23:26 Water pump removal and stress test 25:19 Unbolting the lower oil pan and removing it GENTLY 27:00 Removing the oil pump and balance shaft assembly 28:34 Unbolting the lower half of the block/upper oil pan 30:14 first look at the rotating assembly... there's a problem here? 30:43 Pulling the rod caps and OH THERE IS A PROBLEM! 31:24 The root of all Hyundai Evil 33:03 Knocking the rods and pistons out of their bores 33:41 Unbolting the main caps and FIGHTING WITH THEM 35:18 Butchering the oil pump and balance shaft cassette, how's this come apart? 38:48 Full rotating assembly inspection including the rod bearings, pistons, rings, bores, rods, and crankshaft 44:03 Summary As always I hope you enjoyed this teardown, I love all of the comments, feedback and even the criticism. Catch you all on the next one! -Eric
