Saw this on YouTube, probably the best explanation I’ve seen on this issue so far. Thoughts from people smarter than I?

I wonder if it’s ultimately due to the changes they did when they added VCT, as I don’t really remember there being issues with pre-2009 hemi’s.

That video was added to this thread earlier today. It's interesting to say the least.

Uncle Tony has lots of good and interesting info. My favorite is turning pistons around to get more power. Makes sense with offset piston pins.

Your 2019 most likely has updated parts. I have a good friend who is a Hyundai certified master tech and is certified to work on Chrysler products. He owns two Rams with the 5.7 Hemi. One is a 2011 Laramie and the other is a 2018 Rebel. He hasn’t had any problems. However, he runs 5W30 Mobil original instead of the recommended 5W20.

I’m not worried, it just got my attention. I’ve been debating running 5w30 instead of 5w20 though

Note that the issue has presented on engines that do not have MDS.

We covered the oiling system relatively extensively in the previous thread BTW.

I think he is right. My hemi ticks at low rpm when the engine is cold, exactly when cam lubrication is at it's lowest.

There were these issues dating back to 2004. It's a rare enough problem I would not sweat it. I'm on my 3rd Ram with a HEMI without the problem since 2004.


make the inside of your engine oil cap white.
don't use.

That's usually exhaust manifold studs.

If he’s right about it being caused by a design flaw then it doesn’t seem like we, as owners of HEMI equipped vehicles, can do much about it is there? If oil isn’t reaching the cam then how can using a different viscosity than what’s recommended by FCA going to help?

It wouldn't, as you astutely determined. Also, in the plenty of HEMI lifters that Iv'e seen pictures of, I've not, from failed examples, seen ones with the deposits and scuffs that his had. The bores are pressure lubed, not splash, it's the cam/roller interface that's primarily lubed via splash and it's certainly possible that extensive idling with low levels of oil sling could contribute to roller failure if insufficient oil is leaking past the lifter body and onto the lobe.

That's usually exhaust manifold studs.



It's definitely a mechanical tick. Manifold gaskets and studs replaced on both sides. The tick goes away when revved as the pressure comes up and oil is thrown around more.

May just be a sticky HLA then.

That's possible. I have Valvoline Premium Blue Restore in the sump. Trying to clean things but hasn't been in there long. Tic is more or less the same so far.

Excellent choice! Hopefully that helps.
