Sticky lifter?

I've got a 1990 FSJ GW with 177K miles and it's developed a noisy lifter (I think?). Are there any good remedies that will help until I can get it fixed?

Jeep gauges are for amusement only. Any correlation between them and reality is purely coincidental.

Add a pint of MMO (marvel mystery oil) to your oil. If it's not collapsed and just gunked up it should help free it in time. No it won't clean it instantly nor will it repair a collapsed lifter.

Either one of the products that Joe or Carnuck suggested should work to free up a sticky lifter. I used the Rislone when I first got my '89 and it fixed the lifter noise that I had.

I have a thread about how Seafoam made a new motor out of mine floating here somewhere. I think it's "seafoam - great googleymoogley" or something. But yeah it really opened mine up nicely. I don't go for snake oil but that stuff really actually works. Dump it in just before your oil change, maybe drive it up to the store and back, it cleaned my up w/in a few blocks of driving.
