Just curious of who here has done the DIY highline mod where you move the front fender up and cut the hood. If you've done it, what are your thoughts on the project? Is it worth it? Would you do it again? Is there a real gain of doing it? Thanks, Kevin

2000 4.0 with 187,000 miles. Here's my issue. I have the check gauge light/low oil pressure when engine is hot and at idle. I replaced the sending unit with a Mopar sending unit and still had the issue. Last night, I put in a T fitting and ran a manual gauge with the dash gauge. The...

I have a 2000 TJ 4.0 with the single cat. I had what I believed was a heat soak issue. I installed the DEI insulation kit and things seemed to be better. But here is my current issue. When my engine gets hot, I notice a rough idle and a loss of power at higher speed/higher RPMs. I also...

I posted last month about a possible cracked head. Thanks to everyone's help, I was able to determine that my 0331 head was in fact cracked. I was out of town for a few weeks so I dropped the jeep of at the shop to have the head replaced. I had a new clearwater head for it. I picked it up...
