Meant to add that the overflow hose is clear and the tank is clean.

Hello all. I have a 98 XJ 2 door with the 4.0. I recently had to replace my radiator due to a puncture and ever since then my upper radiator hose gets sucked flat (collapsed) when the engine cools off. I'm running the same radiator cap I was before this all started and it never pulled the hose...

Awesome info there! Thanks!

Thanks for the info. I ran across a set of bumpers on Craigslist for a TJ that I liked the looks of, but if it's going to take a lot of fabrication to make them fit my XJ I'll keep looking.

Does anyone know if a front and rear bumper from a TJ will fit an XJ without a crazy amount of modification?

So it turned out almost all of the catalytic honeycomb was in the muffler! I pulled the cat and turned it on its end and small slivers of metal started pouring out of the cat body. I noticed that the muffler seemed awful heavy when I pulled it so I grabbed a sawsall and chopped it in half. I...

Jeep has 217K on it and was completely stock minus the roof rack & trailer hitch. One of my prerequisites when I was looking was a stock vehicle. Is always easier to start a build form a blank canvas. This one is going to be very mild, in fact I'm going to keep it at nearly stock ride height.

So I cut the muffler off last night and dumped out what must have been half the catalyst honeycomb. The jeep sounded no different without a muffler so I knew the cat had to come the rest of the way off. Well I ditched the cat this evening and went for a quick spin with nothing but the header and...

The uniformity of carbon buildup in the spark plugs leads me to believe that the catalytic converter might be blocked or clogged up. It's a factory mopar converter leading me to believe that it's the original one installed at the factory 217,000 miles ago. The muffler and tailpipe are old and...

Yep, all six plugs are gapped at .030" and all are equally carbon fouled after less than 30 minutes in the engine. I've pulled each one and inspected it when I went back to confirm the distributor index

Plug wires are installed correctly and the distributor index is spot on. Hard to believe the O2 sensor could effect the fuel curve that much.

Hello all, time for my 1st post. I recently picked up a 1998 XJ with 4.0 and Auto trans that looks really nice on the outside, but it needs some help under the hood. The engine starts right up cold or hot and settles in a nice 1,000 rpm idle for about 30 seconds. After 30 seconds it starts to...
