Replacement engine options include

1) Used Engine – A used engine is one that was likely to pull out the vehicle that was wrecked or had damage to other mechanical systems; that ended up sending the vehicle to the service center.

The engine most likely doesn’t have more miles on it and did not need to have any parts changed, so it was simply taken out of the car and placed into a new vehicle. Hence, it is the cheapest method of changing the engine, if one can be found.

2) Rebuilt Engines – A rebuilt engine, like a used engine, was pulled out of the car but it has had some parts changed. It was likely disassembled, cleaned and put back together; with any part that needed to be updated and new gaskets throughout. If the process was done properly, a newly rebuilt engine can last for hundreds of thousands of miles.

3) Remanufactured engine – The best option for replacing an engine in your vehicle involves a remanufactured engine. This means that an engine was taken out of the vehicle and then returned to the factory condition.

Machining of the block, cranks, and heads along with all other parts; to restore their specification; so that the engine operates as if it is brand new. Usually, the remanufactured engine is sold with an extended warranty, but they have more life than a used or rebuilt engine.

4) New crate engine – A new engine required all new parts including an engine block, crankshaft, cylinder head, connecting rods, camshafts, pistons, and valves. Because of this new engine will cost considerably more than a remade engine.

So, you can see there are many options available to you and each has its own features and benefits. Therefore, do your research and make the right choice.
