Hey guys howdy from Texas [emoji112] I have this annoying tick tick noise coming from my 2013 jku 3.6L penstar engine I’m pretty sure it’s a bad rocker, I just thought If there’s any oil additives to help reduce the tick noise you guys might of have luck with?

Thanks for your feedback

Oil additive won’t fix it. You need to replace the lifters. If you leave it too long you’ll wipe out the cam

^^^This. Go get it fixed ASAP before you ruin the cam. No oil additive is going to fix this.

This happened twice to my jeep. Make sure they check all the rockers the first time. They questioned my service records and tried to shift the blame. They will also try to up sale everything. The dealer I took it to tried to sale me an automatic transmission filter until I reminded her I had a manual transmission.

I’ll echo this reply. While I am running some additives every few oil changes, its not so much to fix the lifter issue as it is to keep things running clean and smooth. Mine started making noise around 110,000 and I made the mistake of letting it go. Now I need cams lifters rockers etc. I’m now at the point where putting a new motor in at 157,000 makes more sense.

Any insight into why these rockers are wearing out? Seems like a common problem from these posts. I’m aware of the head issues and extended warranty, but don’t know a lot about the rocker issue. Thanks!

So far from what I’ve been hearing it’s the actual roller bearing in the rocker that is going tits up, or at least in a few cases. Maybe someone else can post up that has a little more insight. I’ve only got a sample size of about 7-8 vehicles with the penitstar, and only 4 of them being in the JK.

What I have done with my 3.8 to help fix a “lack of oil” tick at start up is run 1qt of ATF in the motor for about 30 mins. Since ATF is a detergent it will help clean the slug out of the oil galleys for cleaner passage. I would suggest doing this first to see if it’s just a lack of oil issue due to sludge.

Obviously change the oil after you let it run with the atf in it
