Cars are tricky machines. Sometimes, it can be very difficult to decipher what exactly is wrong with your vehicle. With the engine being one of the major components, here are a few ways you can tell that your engine is failed and it’s time for a replacement.

Check Engine Light

The first sign that there is an issue is the dreaded check engine lights. It’s easy to ignore the light because it’s subtle and silent in nature, but it is the easiest way to spot an issue.

Excessive fuel consumption

If you are noticing that you’re losing gas much more quickly than normal, it could be a sign of a dying engine. While a poor fuel economy can be a sign of other issues, in conjunction with the other signs listed here, it’s a sure sign that something is up with your engine.

Engine Knock

Engine knocking is when pockets of air-fuel burn individually or overheat on their own, not by a spark plug. If not treated, it causes unneeded damage and a lot of cash out of your pocket.

Oil Patches

If there are excessive oil patches whenever your car is parked for a period of time, that could be a gasket or oil pan leak. If these have been going on for a long time, they can cause damage to your engine and perpetuate the problem.

Rough Idle

When your car is idling, or waiting at a red light or stop sign and see how it responds. This means that the car does not stop and wait smoothly and the RMPs will jolt up and down below 600 RMP.

Where Should I Purchase my Engine Repairs?

You will spend the least amount of money if you do the rebuild yourself or with the help of a friend. However, if you get your engine fixed at a dealership, it is more likely to be fixed correctly. It’s up to you and your level of car knowledge to know how to approach this issue.

Engine Repair Kits

Engine repair kits are much more affordable than going to a dealership and you can expect to pay $460 to $730 for a 5.3-liter engine repair kit. It will most likely include pieces such as gaskets, seals, bearings, freeze plugs, and piston rings. Advanced kits may all have pistons, oil pumps, camshafts, and valvetrain parts.


If you have evaluated that it is in your best interest to get your engine replaced, go to the dealership that specializes in your vehicle. For example, if you had a Jeep Wrangler with a faulty engine, go to any approved Jeep dealership to get the details on the costs and length that the car will be in the shop.

Is it Worth it to Replace my Engine?

At the end of the day, it’s sometimes easier to make the investment in a new and working vehicle than try and patch together an old and nonfunctioning automobile. It oftentimes is more expensive than the car is worth to replace an engine, and that is when a bittersweet moment can come in.

You can sell your “totaled car” in exchange for cash and use it towards a new vehicle. The easiest way to get this done is through a dealership, where they may re-sale it or auction it off. They can help you find a plan and new vehicle for your lifestyle.
