It’s about 28° today and I haven’t started the Jeep in about two weeks and it’s sitting outside. Started it up and there’s a pretty good tick while running until it hits about 150 to 160° and then it becomes nice and smooth with no noise the way it should be. Offhand I’m thinking sticky lifter, but someone might have also run into this problem before please let me know your thoughts.
06 4.0 ticking noise
- Thread starter Maddart
- Start date
Classic signs and what I'd assume. There are a few tricks for that, but I'd start with oil viscosity.
Start it , if it starts clicking shut it off , wait 10 seconds and restart it. If the click goes away it is a sticky lifter. Our 99 never does this , but our 04 does it about 1/4 of the starts in the winter. They both get the same maintenance and the 99 has about 50,000 more miles on it . 10W-30 Mobile 1 HM and Wix filters.

If it ticks on a cold start-up, try shutting it off and then restarting it. I have to do it more often in the winter (1-3 cycles).
I couldn’t tell you if my tick would eventually go away without shutting it off (not worth finding out).
Synthetic 5w30 improved things for me compared to 10w30.
I would run a HM oil or the new M1 Advanced Clean to clean up the lifters.
Had a sticky lifter in my YJ, a run of HM back then cleaned it up. No problems since.

Wondering if I should try liquid Molly hydraulic lifter additive
I had a sticky lifter once at 170,000 that ticked when cold. The Jeep had sat for a bit before I started it. I tossed in some seafoam, drove it 100 miles. Changed the oil with 10W30 oil (I run synthetic none high mileage oil). It hasn’t ticked in 40,000+ miles.
Sometimes they get sticky. Sometimes it’s a problem, sometimes they just need love.

You are going to hear about varying results from folks...I've seen plenty of people have their tick to go away (by adding products like Seafoam or MMO), while others like myself were able to lesson the occurrence or didn't get much improvement at all.
The biggest improvement for me was going to an off-the-shelf synthetic 5w30 and then adding Marvel Mystery Oil. I had similar results when I changed to Redline 5w30 (for unrelated reasons). I thought about trying Redline 0w30 (or blending it with 5w30 for the winter), but I couldn't get myself to do it.
I recently watched a video that showed liquid moly and other additives allegedly making the oil acidic when combined with the oil's detergents. I'm not saying not to use LM, but you should be aware that you are mixing cocktails and their can be unexpected consequences. I'd probably try MMO again if I had this happen on a non-turbo rig.

Try using a 5-30 oil in the winter. It will flow better cold and will still protect to a 30 weight. If it keeps ticking, then you can try one o the "oil system cleaners", but I'd stay away from additives-in-a-bottle. Not all additive packages work together, and some fight each other. Also, don't blend different oil types/brands for that same reason. Mixing different viscosities from the same is fine.

Update: 40 degrees today, jeep sat for 3 days started up with no ticking. Only when its below about 35 degrees
