Sounds like a sewing machine?

1992 YJ with 154,000 miles on it. It's the one with the 4.0 engine.

Didn't have the ticking sewing machine sound before but now it's on there a bit more than not. It's worse at start up and sometimes it goes away, sometimes it doesn't.

Checked the oil level and it's at a pretty healthy level. I'm thinking it's the lifters needing some adjustment. Is this the case or is it something else?

Yeah, I'd say it's a sticky lifter. Have you changed the oil since you've noticed it? A lot of times running some new through there will alleviate the issues with it.

Ok, I'll stop by the auto shop and pick up a Lucas. It was the ticking that actually prompted me to change the oil. Used 20W50 hoping it would be thick enough to stick but the ticking kept up.

I'll try the Lucas oil and see if the ticking stops.

20w50 is pretty thick. i'd suggest running a can of engine flush through it, its really mainly keroscene. the stuff actually works, i was skeptic untill i've torn down a motor after doin it. and i've seen it fix noises i was makin fun of guys for tryin the stuff in. run that stuff in there for 5 mins. or whatever, drain oil for as long as you can, let it drip all day if you want, change filter, and add oil.

i am a fan of lucas, i had an old xj w/ 160k that used a qt. a month. after flushing, changing oil frequently, and using lucas, it didn't use a qt between changes. and on top of that, once it stopped using oil, i didn't use lucas either, and it never used a whole qt between oil changes.
"The danger to America is not Barack Obama but a citizenry capable of entrusting a man like him with the Presidency. It will be far easier to limit and undo the follies of an Obama presidency than to restore the necessary common sense and good judgment to a depraved electorate willing to have such a man for their president."
