I have a 95 with a 2.5l and a broke #4 piston skirt. The cylinder shows obvious signs of wear and I’d love to just replace all 4 pistons, rods, and bearings. My question is will this just happen again eventually, or was all the piston slap just a piston manufacturing problem for Jeep and new pistons the solution. I’d appreciate hearing others’ experiences.

Sounds like a tough situation with your 2.5. When it comes to replacing the pistons and rods, it’s definitely a good idea to address the root cause of the issue. Piston skirt failures can happen for various reasons, including oil starvation, overheating, or just plain wear and tear.

If you’re planning to replace all four pistons, it’s also worth looking at the condition of the cylinder walls to make sure they can handle the new pistons. A fresh set of quality pistons should help, but be sure to also check oil pressure and cooling system efficiency to prevent future issues.

Many folks have had success with rebuilds, and if everything is done right, you should see a marked improvement. Just keep an eye on your maintenance moving forward, and hopefully, you’ll avoid running into the same issue again.

Good luck with your rebuild! Let us know how it goes!
