I recently bought my first jeep. What I thought to be a great buy turned out to be not as good as I thought. I've already fixed several problems but here a few that I can't find a straight forward answer to. It burns a decent amount of oil and on start up black soot blows out of the exhaust and leaves a mark on the ground. Another problem that has started recently is a terrible squeal coming from the motor when in neutral and given gas. I have other problems as well but these are the ones I need to get out of the way ASAP. Any help would be greatly appreciated.
belt squeal? is it a manual transmission? black soot could be running very rich. is it a carb or is it the 4 cylinder fuel injected? clogged catylic converter can cause lots of soot. cat could be clogged up and blowing out the soot. the jeep is still probably running rich. the cat got clogged up somehow if it is clogged up.
What do women and Jeeps have in common? The harder you ride them the more money it's going to cost you.

It is Carb, manual trans. If I replace the o2 sensor should it solve the problem if it is running too rich? And if the cat is clogged what do I do about it? But for the squeal, it sounds as if it is coming from the front of the motor. Idk what would of made it start all of a sudden
The previous owner told me he replaced the engine so I have no clue how many miles are on that motor. But I do believe it is stock carb. But it runs fine and have no problems, it just blows soot and burns oil. But I will check all the pulleys and see if that fixes it
The squeal might be coming from the alternator, AC compressor, or just the belt. A worn out timing chain can make noises also, but it's usually more of a grinding noise. As mentioned remove the belt, check it for obvious wear, and make sure everything turns freely. Take a picture of the engine, post it, and we can tell you what you have. If the cat is clogged I have been told it will smell like rotten eggs and/or the cat will get abnormally hot. I have never had one go bad. Finally, replacing the O2 sensor may or may not correct the problem. There are several variables that could be causing the problem. How handy are you working with cars?
Ok I'll make sure to check everything out. Not very handy but me and my dad can usually take care of everything we need to work on thanks to YouTube. He's had a jeep since he was 16 and he just recently put his in the shop 3 weeks ago for the 1st time since he's owned it
