175k mile jeep Loud Lifter sound on startup, Best Additive?

[Ang]

Got this thing and it needed a timing chain. (Skipped a tooth, Broken Guide, Weak Tensioner) it went from a loud tick on startup for 30 seconds before, to a very loud rattling tick for 7 seconds after the timing chain, and the first start it took 5 minutes to quiet down. from what i can tell this is a less common Hemi tick issue with one of the lifters, and im not splitting the engine apart as i just use this offroad. aside from changing off of 5W-20, what is the best additive i can add to hopefully extend its life before it blows up? Maybe some LiquiMoly Hydraulic Lifter Additive? I already have some MoS2 Anti Friction on hand.

People have hhd luck cleaning the lifter to remove noise. You could use VRP. Someone had their jeep lifter quiet after i think 300 miles. Maybe some liquimoly engine flush could speed it up more.

I forgot to add a video, Its there now. Who makes "VRP"? Im sure at 175,000 miles it could be cleaned, but i don't know that cleaning it will fix this startup issue?

Rislone Engine Treatment claims to quiet noisy lifters.

Looks like thats a Cleaner? which would mean throwing out my new oil. i didn't think about a cleaner though, would cleaning make more sense over covering up with an additive?

The whole lifter or maybe just the check valve is likely clogged and it only gets a trickle of oil and takes a long time at startup to get lubricated. vrp is valvoline restore and protect.

It didn't do this before the Timing chain replacement though, Just a very loud tick on startup that lasted way longer. if one is dirty, i doubt the timing chain replacement should have changed what happened from it being clogged..

Doesn't sound awful to me (your video), they do make a bit of noise before everything has pressure, just the nature of the beast.

That said, if it is varnish-related (which is possible), then I'd give Valvoline R&P a shot, see if that makes a difference. I personally avoid any flushes or additives and prefer to just use better oil.

Rislone has stopped a scary loud lifter noise on my F-150. My noise was much louder than yours.

It worked beautifully and inexpensively in my case.

Per their FAQ:

Do I have to flush my oil after using Rislone Engine Treatment?​

No, Rislone Engine Treatment is formulated to be left safely in the crankcase for the life of the oil change for maximum performance. It is not an engine flush and does not require draining.

I used Liqui Moly MoS2 part # 2009 in my 2015 Honda CRV that at about 60,000 miles started a cold start tick for a few seconds every morning. The MoS2 eliminated that issue. My noise was coming from a failing VVT actuator. Your issue is a little different. I would do a fresh oil change, replace some oil with a bottle of Rislone Engine treatment and the MoS2 Liqui Moly, forever. Will it work? I doubt it, you probably need parts, but it is worth a try.

You can use Rislone Engine treatment at every oil change on any engine forever. It is a good slow cleaner, amongst other things. In some cases, it helps. The purists will complain, as it is considered an "additive" and does alter the chemistry of your engine oil, in some cases for the better, I am sure. LOL! Anyhow, you can run it all the time, and it does not need to be flushed out. Just read and follow the directions on the bottle. Rislone part # 4102, if you are wondering which one, as they make a few products.

I would also consider an upper cylinder lubricant fuel additive in addition to whatever you do to the oil.

That does remind me that it now has Valvoline Synthetic blend over whatever potentially full synthetic that it came to me with. That's the only difference I can think of besides the new timing chain.

No additive or oil is going to fix a failed lifter, but if it is just a dirty/partially clogged lifter Rislone is one of the few additives/treatments that has been proven to work.

Me personally instead of any additive I would just run Valvoline Restore & Protect.

Well I just put in Valvoline Synthetic blend, and the rislone is $6 vs VRP costing $20 more than full synthetic oil. I suppose I will have to try that. It's cheaper than liquimoly too.

I'd go with Rislone. It worked very well in quieting down lifter in an Olds V8

Well Valvoline Restore and Protect (R&P) is the only OTS available oil that's proven to actually clean, which is why I recommended it. I'm not going to recommend something like HPL for a 15 year old vehicle with 175K miles on it in a state of unknown health, but VRP isn't any more expensive than anything else off the shelf, so it would make sense to give that a shot.
