Tips & Advice
How long will a rebuilt engine last?
If handled correctly, a rebuilt engine will last just as long as a new engine. With rebuilding, the engine is revamped from top to bottom, and all worn parts are replaced with components that are new or refurbished. The goal of a rebuild is to restore the engine so it performs like one that's brand new.
How long does it take to rebuild an engine?
Rebuilding an engine is a complicated process that calls for meticulous care and specific expertise, and it can take anywhere from a couple of weeks to a few months. The timeframe will depend largely on the availability of the parts required. If the rebuild is being handled by a garage, the garage's workload will also play a part in how long it takes to complete the rebuild.
What causes an engine to need rebuilding?
An engine may need rebuilding due to worn bearings. If bearings are worn, you'll hear loud knocking when the engine is in use, and this problem can ultimately cause the engine to fail. Another problem is poorly seated piston rings, which won't properly seal the engine's cylinders--this can lead to an excessive amount of smoke in the car's exhaust.
How much does it cost to rebuild an engine?
The cost of rebuilding an engine can range from $300-$1,200 or more. Rebuilding costs vary based on the type of engine. Four-cylinder engines are typically less expensive to rebuild than those with six or eight cylinders. Block and head-machine work can further inflate overall rebuild costs.
Is engine rebuilding the same as an overhaul?
Engine rebuilding is not the same as an overhaul. Both work to improve the condition of a car's engine and aim to address damage, but rebuilding tackles this in a more comprehensive way than an overhaul. An overhaul refreshes the engine and extends its life. With a rebuild, the engine is completely restored to a condition that's close to that of a brand-new engine.
What tools are needed for rebuilding an engine?
To rebuild an engine, you'll need a comprehensive set of tools, including an air compressor, engine assembly lube, a basic set of hand tools, blow gun, air hose, brass punch, camshaft bearing tool, electric drill, timing-gear puller, and a torque wrench. You'll need an engine hoist to remove the engine, as well as an engine stand and jackstand.
What is engine rebuilding?
Engine rebuilding is a process in which damaged or worn parts are replaced with components that are new or refurbished. The most commonly replaced parts in engine rebuilding include O rings, bearings, gaskets, seals, timing belts, oil pumps, and valve springs. This process may also involve replacing pistons, crankshafts, and camshafts.
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.
