2001 Wrangler Lifter Noise

I had a 1990 XJ with the 4.0 that started the ticking sound around 60,000. It never got any worse, and was still doing it when I sold it at 276,000 miles.

Dennis did pass the time by typing:

The first thing I would check for is a craked exhaust pipe. Lifters usually don't go bad that quickly, but a cracked header will make noise like you describe.

Another possibility is a cheap Fram(R) filter without an anti-drain valve in it.

Thanks to all who wrote. I will check the exhaust which is something that would have never entered my mind, and I do use Fram filters so I'll check that out also. Thanks again, Dennis

I only use AC Delco oil filters in my baby. It's worth the extra dollar to know I've got a quality item removing the particles.

replace fram with a wix or motorcraft, your noise will be gone.

Easy enough to do. Thanks for the information.

Let us know what you do and what fixes your problem.

If it's actually the lifters, You can live with it until the cam needs replacing.

One of those telescoping magnetic retrieval tools (with the biggest magnet I could find at autozone) easilly lifted my lifters, in a few months when I go back in to replace my cam I will use 6 of the suckers to suspend the lifters off the cam so I don't have to remove my freshly installed 4.0 head (this is an 88 YJ with a 4.2 bottom end).

I put Crane anti-pump up lifters in It's quiet as a new engine now, (helped certainly by the new valve train). But I wouldn't go through all that just to do the lifters.

Definitely try some light mobil 1 for a few changes before you go digging in.

Are we talking about terrorists again.....

Hello, I changed to an AC Delco filter and Mobile 1 oil. Started the engine first thing this morning and it still made the noise, only this time instead of lasting 4 or 5 minutes it stopped after a couple of seconds. It definitely sounds internal.When I got off work and started the engine it was quiet. I can't tell if the exhaust manifolds are cracked the intake is in the way. Next time I have to get under it I'll see if I can get a better look. For now I'm just going to drive it and see how it goes. Thank you all for taking the time to help.
