Can You Install a New Engine in a Car by Yourself?
Changing a car engine is one of the more challenging tasks a home mechanic may ever face. Replacing the engine requires different approaches for every year, make, and model, making it essential to utilize a service manual specific to your vehicle when taking on such a significant project.
My Personal Experience
I have done it. Way back when I was around nine years old, me and my younger brother used to remove the engine from my mother’s Morris Eight Series E and my eldest brother’s Ford Ten so my dad could grind the valves. We left the gearbox in the car, and when Dad had sorted the valve problem, we reassembled the motors and refitted them. It didn’t take a lot of equipment, and I can do the same job today on my own. You just have to know every plug that you undid and every fastener is back in the right place. It’s not rocket science.
The Right Equipment and Tools
Me, yes, I can. With the cars I've had to work on, I have a sturdy Australian Ash tree and a Kelly come along. This rig is good for 1,500 pounds, and most smaller engines and transmissions don’t weigh more than this. However, these were usually fairly easy - inline 4, rear-wheel-drive engines.
Consider getting a Haynes manual, and a quick search on YouTube can provide you with invaluable information. Some engines are a bitch to reassemble, so be careful not to bend an input shaft or something similar. A used Kelly is about $25, and a used chain fall is about $35. Do NOT get under the motor at any time while it is suspended!
Effective DIY Techniques
It is a lot of work, but with some mechanical experience, it can definitely be done with the right tools and a lot of patience. However, if you do not have experience in this, I suggest getting help from someone who does or having it done for you to avoid potential issues. If you have a problem after installing a used engine, the seller may claim that you caused the issue. If you hire a professional, they are typically responsible for any issues.
Expert Advice
There are certain types of jobs with modern cars that require expert attention. In such cases, please call your expert mechanic or the dealer to do the job for you to avoid any regret later. It’s always better to be safe than sorry.
Cheers!
