Q: Possible siezed up engine. on 2001 Nissan Frontier

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
If I had a truck and it will still start but idles rough and blowing smoke out the tailpipe, the engine light is on and a friend (ex mechanic) thinks I seized up the engine due to bad oil (been a while since I had it changed-like 3 yrs). If i have to replace the engine how much would that cost.

But I don't think the engine is siezed if it runs... Unless there's more to tell, it seems to me that an oil change and diagnosing the check engine light is in order first. I assume you're talking about the check engine light and not the oil pressure light, of course. The oil pressure light being on would be a bad sign. Does the engine make knocking noises when it's running? Also a bad sign.
You can do a leakdown test to see if there is compression leakage. In engines that have sticking piston rings due to running on dirty oil, I've had good sccess freeing them by removing the sparkplugs and adding a few ounces of solvent (like paint thinner) to the cylinder and letting it sit for a few days. Then drain the oil, change the filter and run the engine. That may stop the smoke if you're lucky. The check engine light would indicate that the computer detects a malfunction in the engine control system, it's worth the trouble of scanning for trouble codes and data which would be stored in the computer..
