If it ain't broke, don't fix it. If it is broke, make the repairs/modifications that make sense at the time. Sure, I have concerns about the complexity and longevity of the exhaust system, but it isn't going to stop me from enjoying the characteristics of a diesel Wrangler when rock crawling and exploring the North American continent. I've got ~10K trouble-free miles on the odometer, recently lifted on 37's and still enjoying 23+ mpg at 75 mph cruising speed. In my region, diesel is 5 cents cheaper per gallon than regular unleaded. What's not to like?So I had been looking at the diesel for a while and it seems like the way people talk about the Engine/Exhaust system these have a limited lifespan until costly repairs are expected. What is everyone’s plan as these start getting into the 70-100k mile range?
