Crate or a new Engines

A brand new engine that has never been used before presented in a crate is called a ‘crate engine’. It refers to that ready-to-install unit, when removed from crate, which has covered no miles. Normally, new engine can be bought from main dealers only.

As far as the price of the crate engine is concerned, in simple words, they are the most expensive option of all replacement engines. In most cases, their price can match or even exceed the car’s current value, due to the reason that they are the same as come with brand new cars. They demand the highest price among all replacement engines.

Due to their delivery on a crate, they are famous as crate engines. There are numerous automobile companies producing crate engines, yet there could be no compromise on the quality of the engine.

Rebuilt Engines

A Rebuilt engine is the one which has undergone a process of engine rebuild by disassembling some of the parts that are faulty and inspected carefully. The damaged parts are replaced by full functioning used parts which possess the same features and specs.

However, some of the parts are also fixed in order to make the engine work accurately. Therefore, rebuilt engines are comparable to the used engines but are in a certain working condition.

The value and reliability of rebuilt engines depend upon how the mechanics probe into them. Obviously, a proficient mechanic will be able to rebuild a more durable engine than that of unprofessional one.

The rebuilt engines are presented in working conditions, even though they can carry cracks and damaged signs. In short, it can be stated that these engines are less durable and can experience damage for a second time. However when it comes to the price, rebuilt engine works out to be the cheapest option of all.

Reconditioned Engines

Reconditioned aka ‘remanufactured’ engines are durable and offer long-lasting performance. They have to undergo a lengthy procedure of reconditioning. They are prepared to compete

with the brand new engines. Here, also the reliability depends upon the people who are remanufacturing the engine.

The engine for remanufacturing is first taken out of the car then stripped to parts. The parts then are cleaned thoroughly and all dust, grease and oil are removed. This process also involves the brushing of the engine block, crankshaft, connecting rods and pistons. This process can only be carried out by the certified engine professionals, as it requires much experience and proficiency to complete.

The next step for engine reconditioning accomplishes by verifying all major parts for failures

and defects. After this, the damaged parts are fixed, defected parts are removed and new parts are installed. The friction between parts is reduced by polishing their surfaces.

In the final step, the engine is reassembled by using hi-tech equipment and electronic machinery so that every part may be assembled with due care and perfectly. After the completion of the last step, the engineers in the state-of-the-art garage test the performance and efficiency of the remanufactured engines. The remanufactured engines are not offered for sale until they pass all the reliability and durability tests. The positive response of the engineers makes the engine ready to be sold in the market.

The cost of the remanufactured engine is a bit higher than the rebuilt engines yet far less than that of a new engine. Unequivocally, the reconditioned engines are backed with more warranty than the rebuilt engines. The efficiency of remanufactured engines is on a par with that of new engines cause of the fact that they have to go through the meticulous process to be proficient all in all.

Low mileage Used or Second-Hand Engines

A used engine is one that has already been used in another vehicle and has done some mileage. Generally, a used engine is taken from a damaged vehicle, normally from an insurance write-off and has been used earlier to being taken out. Ideally, each used replacement engine has to go through extensive quality checks and only if it is up to the pre-set standards of the shop it is allowed to sale.

The mileage of used engines may differ in the cars in which they are fitted afterwards. These low mileage used or second-hand engines may also come with surplus items such as manifolds and injectors. Though, it is suggested to use the genuine components since no one can pledge the proper working condition of these gears. No warranty shields the engine parts which are left on the engine.

  1. Thanks for this advice for buying a replacement car engine. You mentioned that the engine is reassembled with high-tech equipment. I’m kind of interested to learn if some reassembling equipment is more ideal for some engines depending on their design.

  2. If I had to get an engine for my car, I would probably go with a remanufactured one. That way, I can be sure that it would be able to work properly after being reinstalled into my vehicle. I would also be sure to get someone to do the work for me as I don’t have the mechanical inclination to do it myself.

  3. I’ve had my car for a while, so I wanted tips on maintenance and engine repair! I didn’t know rebuilding your engine was the cheapest option since you’re only replacing parts that are damaged. My dad offered to help me fix my car, so I’ll have him look at my car and I’ll find the auto parts I need to be replaced online, thanks to this post!
