Hey All,

I recently purchased a 2018 RAM 2500 Tradesman with the 6.4L Hemi in it at auction on a whim for basically nothing. It was listed as a non-runner and I assumed it was likely something rather stupid/boring and the truck was cheap enough I was willing to take the risk.

Well, this one bit me in the ass and the engine is locked up (yes, I took the belt off, tried to turn it over manually with a breaker bar - no movement at all). Body is in good condition, interior is in good condition and for a work truck in Texas - its fairly low-mileage.

So I am trying to find another motor to put in it. I've found one I am interested in online - no core charge, free shipping and price is acceptable, lower miles than the truck I have ... but ...

The donor vehicle was a total loss due to a roll over (I saw the photos of the truck), sold at IAA by the insurance company (so all good there) without keys. The engine compartment survived the wreck completely intact (drivers side cab took most of the damage).

My only reservation here is whomever was driving this thing was definitely not in the condition after the accident to think "I better turn the truck off" given my the amount of blood on the driver's airbags in the cab.

I cannot rule out that the truck was running upside down for an unknown period of time. My understanding is there is no inertia switch or emergency fuel cut-off incase of accident or roll over. The hemi is wet sump and like most truck rollovers, was nose down (so the highest point in the engine when the truck was inverted was the oil pan).

My concern is that if the thing kept running for 15-20 minutes before emergency services got the guy out - the bottom of the motor was starved for oil and I'll put it in and it'll be knocking right off the bat.

Are my fears unfounded and I am just being paranoid or is there some legitimacy to what I am wondering?

Best,

Eric

Thanks for the welcome - I don't recall ever seeing one still running either - but I couldn't find any information otherwise in the owners manual or online.

If the bottom of the feeder line in the gas tank is "in the air" then the truck should have stalled out within 15 seconds or so - but I don't know how much gas was in the tank at the time. Just wild speculation at this point.

Don't most vehicles have a fuel pump shutoff switch that kicks in with impacts?
