Is it worth replacing an engine?

Only if the rest of the vehicle is solid (transmission, body, suspension) and the cost is under 50-60% of the vehicle value.

Used vs rebuilt vs new crate?

Used = cheapest, shortest warranty, real risk. Rebuilt = mid-cost, mid-warranty, predictable. New crate = most expensive, longest warranty, like-new.

Will replacing the engine reset the odometer?

No - the odometer reads on the dash. Most states require the prior mileage to be disclosed; replacement is noted as "engine X miles" separately.

How long does engine replacement take?

15-25 labor hours, but most shops take 5-10 working days due to scheduling, parts ordering, and break-in cycle.

What kills an engine prematurely?

Running out of oil, overheating, hydrolock from water in the intake, timing belt failure on interference engines, and severe detonation.
