This is only possible until the engine under the roof of your car is proficient enough to put up with the hurdles on the road. But the time you develop a loving relationship with it, the engine starts making unexpected glitches. You can’t even change the vehicle and get stuck in what to do next. That’s something no one expects at any cost.

Be that as it may, hold on. Nothing is to worry about this. The option of a replacement engine has made it possible for you to bless your beloved car with a new life. This is a very effective option to save unwanted engine repair and labor charges. But before heading towards the replacement engine, let’s give a look-see to the factors determining when engine replacement is necessary.

Factors defining the need for a replacement engine

There are many motives that point you to go for a car engine replacement. At times, engine repair is required at the most primitive to save the engine, or else the engine will be ceased and replacement will be the only solution left behind. If you go for engine repair earlier, you will be able to save expensive treatments for your vehicle which may suffer you a lot and you can reduce the bills.

The need for Replacement Engine

Having said that, you’ll be standing in the need of a replacement engine if your engine has been broken down. That being the case, there are several reasons for engine failure eventually leading to acquiring the services of a replacement engine. A few of the common problems are as under:

Oil leaks

Yes, that’s a major cause behind engine failure and it should be handled with utmost care- no ifs, and, or buts about it. No one can give oil leaks the brush off when it comes to engine failure.

The main reason behind the oil leaks is the low-quality gaskets, oil pins, or oil seals. Just delving into what is causing engine oil leaks can get the job done and if there’s a danger of massive loss fixing it yourself, it would be fructiferous to see your mechanic.

Engine overheating


To be brutally honest, the cooling system of your car should work properly and if it’s not up to the mark, engine overheating will show itself up straight away. The experts recommend consistent servicing of the cooling system plus keeping watch on coolant fluid systematically in this case. If you notice overheating of the engine, get your cooling system checked immediately.

Engine overheating

Improper lubrication

Well, the function of lubrication inside the engine is lessening the friction between the movable components of the engine. Not only that, the engine bearings and the rods would cool down due to less lubrication inside the engine. All the components of the engine will catch heat at all speeds which makes the engine seized immediately. Thus, proper lubrication for the engine to work evenly on the road is something really important. That’s a given.

Oil sludge

Oil sludge gets well with the passage of time and that’s something responsible for engine failure if not given intensive care. Regardless of the make, you drive or how hefty the engine under the roof is, oil deposits can turn out to be a real bear and without the regular maintenance, these can give rise to catastrophic engine break down.

On the whole, oil sludge means the emergence of huge deposits of oil in the engine’s crankcase. Because of this reason, the coil won’t be fit to provide the movable components of the engine with adequate lubrication and ultimately resulting in engine failure after a short span of time. In a general run of things, the oil deposits are the result of exiguous service or acquiring the services of poor quality oils.

Wrong fuelling

Wrong fuelling is another big cause of engine failure and it’s a common mistake that motorists make. Filling the wrong type of fuel into your engine can destroy the entire engine and you’ll be standing in the need of a replacement engine. There are two kinds of wrong fuelling comprising diesel in a petrol engine or petrol into a diesel engine. Around 150,000 drivers in the UK fall prey to this catch-22 every year. You can take several preventative measures to avoid this disaster.

Type of replacement engines

Let’s take a glance at the types of replacement engines available in the market. The first type is the crate engine that is brand new and presented in crates. This type is the most proficient and expensive one. The second type is the remanufactured engine that is old but has gone through an in-depth process of remanufacturing in which new parts are replaced by the damaged ones and the whole process is carried out by the professional technicians.

The third type includes the reconditioned engine. These engines also undergo the process of reconditioning in which damaged parts are fixed or replaced by some other parts in proper working condition. The last type includes the low mileage used engines or second-hand engines. These engines are taken out of some other car that has been damaged in an accident. These are the cheapest replacements but not as durable as a crate, recon, or remanufactured engines, yet can serve your purpose. But be aware to get your car checked by some expert mechanic and ask them to suggest a suitable replacement engine for your car.

The right type of replacement engine

Once you get a green signal from the mechanic to replace the engine of your car, the next thing to ponder upon is the most suitable replacement engine. How shall I determine which engine to opt for? Just be relaxed and ask your mechanic. He will surely recommend the best and make sure to discuss the price you can afford. The remanufactured engines are more expensive than reconditioned and low mileage used engines. So, go for a replacement engine that is pocket-friendly and serve your need too.

Inspection by Mechanic

The discussion with a mechanic doesn’t mean you can’t judge on your own. If you have enough knowledge about engines just take an estimate from a trusted and experienced mechanic. An unknown and inexpert mechanic can only add to your worries rather than shedding them away. And, anyone driving a vehicle for a long period of time develops good relations with the mechanic who can give an expert view but if you cannot trust anyone, you can ask online from many portals. They will surely help you all in all.


Having said that, the prices of replacement engines vary from type to type, crate covering the top and then remanufactured engines. After these, reconditioned engines are a bit costly and then the low mileage used or second-hand engines are the cheapest. You can get quotes from different online portals and then compare the prices. Remember, don’t be a notorious tight-arse because it can cost you double afterward.


The next important thing to consider is the warranty offered for each replacement engine. Warranty is significant in the sense that it can make you secure and feel easy. It ensures the vigilance of any shop offering replacement engines. The warranty also differs in accordance with the type of engine. Remanufactured engines possess a greater warranty span in contrast with the recon and low mileage used engines. But the average warranty span of the replacement engine is two years.

Look for a trusted Company

Yes, that’s something needing huge attention. While shopping around for a replacement engine from the market, you must look for a well-reputed company. Give all the customers reviews a once over with a fine-tooth comb before choosing the company. It’s multum in parvo to pick out the top 4 companies and see what customers say about them. And then make the final decision and it’s something you must fix your gaze on.
