The Problem with Most Used Engines

We’ve all heard the horror stories. Someone buys a used engine off a classifieds site or a sketchy online store, only to find out it’s leaking oil, missing parts, or flat-out doesn’t run.

The biggest issue! No testing. No warranty. No way to prove it’ll last more than a few days.

Used engines, when bought blindly, are a gamble. And that’s the last thing you need when your car’s already down for the count. That’s why buying used engine with warranty is not just smart—it’s essential.

What “Fully Tested” Actually Means

Let’s clear the air—“tested” doesn’t mean someone just looked at it and said, “Yup, looks okay.”

A properly tested used engine has gone through a full inspection process. That usually includes:

Compression tests on all cylinders
Leak-down tests
Visual inspection for cracks or wear
Oil condition analysis
Engine run tests (where applicable)

Some sellers even provide video proof of the engine running or written test results. That kind of transparency matters. It’s the difference between peace of mind and playing roulette with your ride.

What’s the Deal with Engine Warranties?

Used engines with warranties are like gold in the car world. They tell you two things:

The seller stands behind the engine.
You’ve got backup if something goes sideways.

Warranties usually range from 30 days to 3 months—sometimes even a full year if you're lucky and are willing to pay a little extra. They may cover parts only, or in some cases, even labor. Always read the fine print, but having any kind of warranty beats the heck out of buying blind.
