Your car just left you stranded on the side of the road and you can’t afford to go out and buy a new one. The mechanic says it’s the engine so you either need to have it rebuilt or replaced if you want to keep the car. Now, you have to decide what to do.
What happens when an engine is rebuilt?
A rebuilt engine is also referred to as a "reman" engine (remanufactured). The engine has been taken apart and everything cleaned. All of the parts have been inspected and worn items have been replaced. The parts are then put back together to create a rebuilt engine that runs and meets OEM (Original Equipment Manufacturer) engine specifications.
The most common components to be replaced include rings, bearings, gaskets, seals, timing chains, valve springs and the oil pump. Major parts are replaced only if they are needed, and often include camshafts, crankshafts and pistons.
If severe damage occurred to your engine, the engine block may have to be bored to align the crankshaft main bores. The cylinders may need to be bored to fit new pistons. This is more extensive work, but it will allow the engine to work once again.
The advantages of rebuilding
Once the engine is rebuilt, you know everything has been closely inspected and it has many new parts. It will extend the length of life for the engine. How long it will last depends on how many components were replaced. Another benefit is that you are recycling engine parts to help reduce the amount of scrap in the environment.
