How long does a Chevy engine last?

Depends on how the engine was treated and how well it was maintained.

Mine’s a 2002 and I’ve got about 230,000 kms on it so far with no issues. Runs great, still got decent power and doesn’t use any oil. Hope that helps!

I have had several friends with Cavaliers and they pretty much suck for lasting a long time. Im not sure about the newer models (02-05) but I know the models in the 90s and early 2000s break down alot, which probably why parts are cheap. However a chevy engine (V-8) last very long and are reliable. Any car, as long as you maintain it (oil, tune ups, ect..) it should last for a pretty long time.

depending on how well it was taken care of, my 89′ 4×4 had 270,000 miles on it until the block cracked.

If you take care of it properly and dont abuse it will last a long time. Ive seen many chevy motors work well in the high 200,000 mile ranges.

if they are maintained right they last about 160,000 miles, well at least the never once but the older once don’t last as much.

After 150,000 miles you can expect break downs with any vehicle
If the oil has been changed and the rest of the car has been well taken care of you could get 300,000 miles
BUT not trouble free
You will have repairs in any vehicle with such mileage
