Smoke And Loss Of Power!!! Is This

The Catalytic Converter?


I change my oil two days ago....It recently began to smoke! Fresh tune up, and everything. But I do hear a rattle sound as if a rock is in something under the truck. When I accelerate it gets louder! PLEASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSEEEEEEEEEEEEE HEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLLPPPPPPPPPPPP

Thank you kindly!

Check your fluid levels. Sounds like an oil problem.

What color is the smoke? What Year? Engine?

if its the 93 blazer thats on your profile it could be anything, depending on milage, usage and a dozen other things, need more info.
get under the thing when its running, look DON'T TOUCH!, at the converter. if its turning red its bad. 3 options
1. remove converter and put test pipe in, will tell you if its bad but in most states that have emition standard not legal to run that way.
2. remove converter and have some one clean it out, or cut it open and clean it out and weld it back together, again not legal.
3. if you are sure it is the converter, and the only way to tell for sure is to use test pipe. replace converter, most emition equipment has at least a 10 year warrenty.

first off give us some more info

If you over filled the oil you may have blown a seal.

That will make smoke and lose compression.

DON'T DO THAT!!! Sheesh nothing could be dumber than to get under the vehicle when it running. Let it run for a while, turn the f**ker off. block it so it won't roll and then slide under it.
