Bad Lifters?

OK, my engine, 4.0L 6 cylinder 2000 Wrangler, was making a horrible racket so I took it in and they replaced my lifters, and it fixed the problem. I won’t tell a DIY crowd how much it cost but my question is why. I baby this thing, it only has 25K miles on it, no high revving, very minimal off-roading, no extreme driving what so ever. I just want to make sure it doesn’t happen again $$$. I actually wonder if I don’t drive it enough – get the oil moving around.

Could be a defective rig right off the manufacturing line. It is a heep however. Unless it comes right outta japan/china, and right off the boat, american rigs will always be less quality. HOWEVER, parts/labor costs less on our rigs then theirs.

The lifters in the engine are "pumped up" by oil pressure. If they're not pre-filled before running the engine the first time, they can be damaged. This may have been what happened with yours, a bad day at the factory or something.

I wouldn't worry about it, things should be good to go from here on. However, if the same thing happens again I'd suspect a different problem and would ask them for a new engine.

Make sure that the warranty is extended also, from the date of repair. Don't know if this is possible, but worth it to ask.
