I'd look for a used engine (either at car-part or see if a local wrecker can source one) to drop in and a decent mechanic to do it, if not tackling it yourself.

A new engine in a 2017 is probably not very economically viable unless you plan to drive it into the dirt.

 

Do you mind me asking how much added HP you were running on the vehicle? You said it was pouring coolant, where did you see it coming from? Did you see any oil leaking from rear main seal or near the bell housing? Did it start bucking or chugging when it went? Any other things that you noticed?

 

I like my diesel truck a lot, and if I were in your shoes (paid off)..... I'd still have a hard time dropping lets say $20K into it.... with a blown engine.... does it have any residual value?

$25k is a long way towards a new truck.... just saying.... will have more value then a used engine in your current truck

 

Sorry to hear about the failure. If the issue ends up being a fractured piston then there's no need to replace the entire engine, let alone with a new one. When this happens it's usually possible to just replace the failed piston. It's not easy, but it's much cheaper than replacing the engine. Failing that, find a reman or low mileage replacement. Below are USD and roughly half the cost compared to whoever quoted $14k + labor, which is robbery.

Duramax Diesel Wholesale - a Division of US Engine Production - $6800 for a reman long block
GM 2.8L Duramax I4 LWN Remanufacture Long Block Engine - $5600 for a reman long block

Complete used engines tend to be around $8000.

Getting a new/different vehicle is the easy but more expensive route, if the rest of the truck is in really good shape then I'd definitely pay a reasonable amount to have it repaired/replaced. The way I think about major repairs like that comes down to vehicle replacement cost vs repair cost. How much would it cost to replace my truck with something comparable? A lot more than the repair, which should hopefully be a one-time expense. Obviously expensive, repeat failures quickly reduce a vehicle's value to zero so it doesn't make sense to keep pouring money into it and it's time to move on. My truck is still in great shape and built out the way I want it, so if I were in your shoes I'd probably be looking at $25k or more plus whatever value my truck had left after the failure in order to replace it with something similar. So, spending around $12k to replace the most expensive part on the truck would make more sense as the truck is otherwise excellent and not showing much wear/age.

Everyone's situation is different, but I'd definitely be talking to other shops because that estimate is nuts.

The thought of replacing my truck makes me cringe because of how expensive vehicles have become.
