Jeep Runs Great - What Am I Doing Wrong?

Other than a minor oil leak from the rear main seal or oil pan gasket and the oil fill cap my Jeep runs great. Should I be concerned?

Yes. Something is definitely wrong here. To correct the problem and feel better about your situation, I would at minimum, disconnect one plug wire. If you are still concerned, disconnect two.

But you shouldn't be overly worried. You have your oil leaks to fall back on.

Hang in there! Remember: Great Running is no more than a passing phase.

nah. i never had a problem with jeeps not running great. every once in a while you have to change an alternator or water pump, sometimes the starter too but for the most part, they always run great

I would start by randomly replacing parts that could easily be tested to see if they are working. Nothing beats throwing money at the problem of a perfectly good running jeep.

Now, go fix that troublesome squeak, or that annoying rattle!

I'm really in trouble, I replaced my rear main seal so my jeep doesn't even leak oil. I go out every day and look underneath, but no drips, I need to replace something or I feel unwanted.

You can fix this problem with a V8 project, or at least an axle swap. Then you'll have plenty to work on!

Buy another Jeep.

The first one will be jealous soon enough and start acting up just for attention.

I'm sorry you have a great running Jeep YJ. It does happen to the best of us. My advice is that you need to plan ahead to keep your Jeep barely running and in need of replacement parts. Here's the YJ Forum Top 5 Tips to help ensure you always have either a poorly running YJ or at least something that needs doing daily:

1. Throw Out Your Multimeter - not having a basic electrical analysis tool like this will help ensure that when you suspect something is wrong, you can go down the list of sensors and fuses, replacing them one at a time, until you sense something is right.

2. Use Cheap Parts - there is no better way to ensure that the throw out bearing you just replaced will need to be replaced within the year than using the absolute cheapest parts. This holds true for after market sensors and grade 5 bolts as well. If you always want something to do (again) use cheap parts.

3. Mod Madness - many here suffer from this debilitating disease, upgrading or modifying for the sake of upgrading or modifying. Do you absolutely need angry eyes? Naw.. but they look soo cool! How about playing the Treasure Hunt game at the local pic-a-parts to cobble together a Taurs fan mod? That will definitely occupy your time. Now mind you, some (but not all) of these favorite mods are useful and practical, but what you really get is the continual tweaking, adjusting, and scrounging - and that's what keeps you busy. Your jeep may run just fine, but as long as you have something to mod or replace, it's as if it runs horribly.

4. Don't Listen - If you insist upon only doing what's necessary to fit your style/terrain off roading and you refuse to use cheap parts, your only other hope to keep yourself busy with projects and a poorly running YJ is to post up questions here on the forums and then insist on replacing parts that are unrelated to the fixes posted in response. If everyone is telling you to test your TPS, simply state you are replacing your O2 sensor. When that doesn't work, replace random parts - avoiding the actual fix - and you'll be busy for decades.

I know what it's like to have a sound, well running YJ. I was forced to drive it nearly every day. I solved my issue in a rather unique way - I bought a basket case XJ to fix and flip.. two months later and I haven't had a spare minute for my YJ.

I don't even have an oil leak.

My problem? My windshield washer reservoir. It build up pressure on warm days and pushes washer fluid all over the hood. Not sure how to fix. Was thinking of putting a pin hole in the cap.

That is my main issue right now.

Wow! your jeep is peeing on your hood? You must really have pissed it off, that or it's marking it's territory in an original way.

If my Jeep is not leaking oil from somewhere I know something is wrong. I just grab a hammer and screw driver and punch a hole in the oil pan....she always runs so much better.

Tired of my friends saying, "dude, your Jeep is leaking sumthin" and it turns out to be washer fluid.

What kind of mod to fix this? maybe a part from a Yugo?
