2020 with 13,000 miles

[Slayer1962]

My truck is a 5.7 hemi and has 13,000 miles babied. towed a boat three times otherwise its a car.
Oil was changed 3 times at the dealer so far ( free)
I do not drive it daily anymore i have a car for work. I went to use the truck to pick up some bags of clothes from my parents last Saturday.
When i started it the lifters tapped. I used remote start and no throttle applied .
The truck had not been started for a couple weeks. Oil is full and clean ( only 900 miles since changed)
Is there an additive that i can add that would coat the engine better? The truck might sit 3 weeks sometimes.

I wouldn't sweat it. There's a lot of engines other than a late model hemi that will tap and clatter for a few seconds after cold start after sitting unused for weeks. If this was a more regular issue, I'd take the board's advice on oil and/or additive choice.

FWIW, for my 2019 Ram 1500 classic w/ hemi, I run supertech 5w30 synthetic and add a bottle of Lubeguard biotech, or LiquiMoly MoS2, or nothing, depending on how I feel. I kind of rotate between the 3 choices.

Isn't there an oil filter that has an anti-drainback valve that will solve this issue? I seem to remember reading about this somehwere....I could be wrong, because I normally am.

It's not something I would sweat either. There may be one lifter that may bleed down if the engine so happens to stop with that lifter on top of the cam lobe holding that valve open for the period of time before you start it again. the engine may stop on that particular place once every hundred stops. I've seen engines run hundreds of thousands of miles in that situation but I understand your concern, I wouldn't "want" mine to ever tap either!

There is nothing that can prevent this and it will happen especially with a hemi, even the fixes the forum have figured out over a decade, those are only mildly successful IF a truck sits this long. Even those of us who have solved hemi tick with a lubrication strategy, will have tick if the truck sits for weeks, if the truck is prone to tick, not all of them are, but a lot do. Furthermore, our filters are always full because they are not located on the side of an engine, as many times as I have changed my oil, the filter is always full, anti drain is supposed to keep oil in the back lines, but it doesn't regardless, why- because when you turn an engine off the engine is hot and the oil is as thin as water, no anti drain valve will keep that oil in the filter, but for us it doesn't matter because our filters aren't sideways.

Lubegard biotech can possibly help, it is esters and moly which is what the industry uses for dry starts. But when a truck sits that long those lifters are really dry, may or may not help. Also, redline 5w30 and a royal purple have proven a real answer for tick and has the most additives to prevent this, but of course is more of a commitment then just tossing lubegard biotech in there. Mos2 might help as well, but there is a downside to this product, it gels the oil in your sump, which is why every oil manufacturer that uses moly and most do, went to modtc, or oil soluble moly as the moly in redline and biotech. redline is not an api oil and fca doesn't recommend additives, so if that bothers you all you can do is look for the highest moly count in an oil that carry ms6395, likely rotella truck and gas, but I think you will have more success with what I posted earlier.

Now, if your truck warm idle ticks, as in if your engine is plenty warm and it is ticking, PM me and I will send you some ram forum links done with the help of 100's of ram forum members in 4 gen over a decade. but dry tick like this, your best defense is starting the truck once a week and run it til the idle kicks down then turn it off.

No worries, hemis are notorius for this. My 2015 Challenger Hellcat ticked on warm up. Nature of the beast.
