2014 Ram ecodiesel engine failure

[Wadem]

Hello all, I’m in a real bind and hope y’all will chime in with some ideas. To make a very long story short, I bought a used 2014 Ram eco diesel in 2017 with approximately 80kk miles on it. I’ve put 140k additional miles on it since 2017. The first 2 years I owned it dodge replaced 4 sets of injectors and it’s currently got it’s 4th different EGR cooler. Also about 3 months ago it was throwing a code and the dealership replaced the intake manifold. I was worried that the leaking EGR coolers might cause me engine problems down the road but in 2019 the had a big emission recall that extended the warranty on almost everything on top of the engine for an additional 48k no matter how many miles it currently had. Fast forward to last month when I was using cruise control at 70mph my speed started dropping rapidly. No dash warning lights but when it didn’t respond to my foot on the accelerator I pulled over immediately and the engine had shut off on its own. I popped the hood to check for overheating but it hadn’t overheated. I then crawled underneath and there was oil everywhere covering basically the entire bottom of the truck. I then had it towed to the dealership where after 2 weeks they told me that a turbo feeder line had ruptured and since it was under pressure it pumped all the oil out while I was driving. They said that luckily the feeder tube was covered under my emissions warranty. After they got that repaired they called me to say “now your engine is locked up!” They said it must be because the feeder line rupture leaked the oil out while driving and that an engine should be covered under the warranty since a warrantied part caused engine failure. Great news until they called me back and said Chrysler demanded oil change receipts which I didn’t have because I change my own oil 80% of the the time and didn’t save any. They then dropped the oil pan and said they found bearing debris and sludge so they won’t cover the engine damage. Now they want me to pay them $13,000 for a new engine and they want to charge me $35 a day for the rental car they gave me back when this first happened. I know the truck has a lot of miles but to me if a part covered under warranty fails and causes engine failure then the engine should be covered, isn’t this considered “causible damage” also, I’ve always been diligent about changing the oil and fuel filter both before they we’re actually due. Maybe I’m just screwed but wanted to see what y’all think. Thanks in advance for any advice
