Tips & Advice
How long will a remanufactured engine typically last?
With the proper maintenance and adherence to driving within in the guidelines of engine performance designations, remanufactured engines can last 100,000 miles or more. With modern technology, engine lifespans have dramatically increased over the years. It is not uncommon for engines to last 200,000- 300,000 miles, or more--before a rebuild or remanufacture is even necessary.
What is the difference between a remanufactured engine and a crate engine?
While remanufactured and crate engines are very similar, there are several key differences. The biggest difference is that crate engines are as close to new as possible, without actually being new. Everything internal is replaced, which is not always the case with a remanufactured engine. Second, crate engines do not have to meet factory original specs. Some are upgraded to high performance engines through specialty shops. Crate engines are ready for immediate installation. These factors tend to make their price point higher than for a remanufactured engine. Adherence to factory specs is the biggest difference; remanufactured engines are required to (with some exceptions), crate motors are not.
Do remanufactured engines come with a warranty?
Remanufactured engines nearly always come with a warranty. There may be exceptions, so it is important to learn the specifics of the auto shop. There is no reason for a shop to not offer a warranty on what is basically a new engine. While not getting a warranty would be rare, confirm the engine comes with a warranty prior to making any commitment.
Can all gasoline and diesel engines be remanufactured?
All gasoline and diesel engines, with some exceptions, are eligible to be remanufactured. Old, rare and out-of-stock engines, engines with cracked or damaged blocks, and specialty engines are examples of engines that might not be eligible to be remanufactured. Also to be considered are parts availability and a mechanic’s knowledge of a particular engine. Most modern and popular engines are eligible. Lower- end production and rare engines might require specialty shops that work in these areas.
What are the most commonly remanufactured engine types?
The most commonly remanufactured engine is the inline four-cylinder gasoline engine. It is the most mass-produced engine in the world and is the primary power plant in the most popular cars in the world, like the Honda Civic, Volkswagen Golf, Toyota Corolla, and the Ford Focus. The next most common remanufactured engine is the straight, or “‘inline” six, a six cylinder that is a larger and more powerful engine popular in many smaller, light duty trucks, SUVs, and an engine option in the Toyota Camry. The popularity of these cars and these engines makes them the highest in demand for remanufacture.
How competitive are the prices for remanufactured engines?
Prices for remanufactured engines have become extremely competitive over the years as the business has moved from predominantly factory-affiliated shops into the mainstream. Virtually any shop with the correct tools and skilled labor can remanufacture engines. Rural shops have the luxury of cheaper floor space and labor, keeping them competitive with more urban shops. Competition in the space has driven prices down in recent years.
How long does it take to remanufacture an engine?
The length of time it takes to remanufacture an engine is dependent on many variables. The condition of the engine is the No. 1 factor. How much wear and damage is involved? What is the competency level of the mechanics and the machine shop? Are you looking at a 1969 Chevrolet V8 396, or a 1999 Subaru four cylinder? How readily available are parts?
A remanufacture can be done in 3-4 weeks at the earliest; other times you can be looking at up to six months, possibly more. Consult the shop doing the work. Another alternative is to purchase an already remanufactured engine and do an engine swap, which can be done in a matter of days under ideal conditions.
How is an engine remanufactured?
Engine remanufacture is a basic process, with variables. A remanufactured engine is completely taken apart and broken down to the block. The block (and heads) will be machined to original specs if damage or wear deem it necessary. From there, worn internal parts are replaced. Systems like pistons and rods, valve train (which could constitute new heads), bearings, intake and exhaust systems, ignition and electrical, and crankshaft and cams are all replaced or machined to factory specs and then reassembled. The resulting engine is designed to meet the same specs as the engine that rolled off the assembly line and is tested to confirm it does.
Is a remanufactured engine the same as a rebuilt engine?
A remanufactured engine and a rebuilt engine are not the same thing. In a rebuilt engine, the engine is rebuilt up to the standard of the faulty part. For example, if you blow a piston or rod, the engine block will be removed and the broken piston or rod, and all mechanical parts related or damaged due to the failure, are replaced. This could include machining of damaged parts. It is not meant to meet the original manufacturer’s specs and performance, like a remanufactured engine is. However, it can result in an engine that exceeds the original performance standards if the owner chooses to upgrade. This will increase costs, but is common among automotive enthusiasts.
What is a remanufactured engine?
A remanufactured engine is a used engine that has been completely disassembled, and then reassembled with mostly new internal parts, the quality of which meets the manufacturer’s original specifications and standards. While not every part is necessarily replaced, all worn parts are and machining may be done to make sure the engine meets correct factory specifications.
