I'm not a car guy so I'm trying to get a sense for the validity of "Yah, you're going to need to replace the whole longblock" without a full diagnosis.
Partial diagnosis received:
"Thermostat cracked and all fluid drained out causing overheat.
Car turns over without compression.
Remedy: Replace the engine.
I'm getting a second opinion from a shop that works on LR's but my question to the group is - >"Before the catastrophic failure, I think the car ran max of 10 minutes at ~ 30 mph and ~ 1 minute at ~ 40-60 mph before alarms sounded and it shut down. Is that a scenario that would typically lead to requiring a full engine replacement, or perhaps lesser incremental failures?"
I understand that I'm asking people to spitball, and I'm not going to lawyer up about answers; I just don't have the experience to spitball on my own. Help appreciated.
