I think you are making too much of nothing here. That is normal sounding to me. The noises might be coming from cold belts and other things.

My Mazda has some kind of quick warm up mode that make the engine sound loud when it's cold. I think it's part of the exhaust system but I cannot remember the details. Yours might be using a similar type of setup.
 
My 2015 Caravan makes a similar noise on a cold start. I'm using Valvoline Synpower 5w-20. If I use the block heater the noise will go away faster. When using the block heater, I set the timer to only come on for 60 mins before I leave in the morning. No need to run it for any longer, you're just making the Hydro Company more $$$.

Exactly.
 
No it's not captured well in this video it does sound like marbles. The whine / groan is normal for these engines but the Marble sound which isn't easy to hear in the video isn't normal and happens only for the first few seconds...

I'll see if I can capture it better.
 
I thought I was obsessive. But Stevie, reading your posts makes me realize you take it to a whole other level. All this overthinking, experimenting and "fixing" must be exhausting - it's even tiresome to read about all the "issues" with your vehicles. You must have a very understanding partner to put up with all this nonsense.

Mine makes the rattle/marble like noise if it hasn't been driven in awhile (3-4+ days) or if it's really cold out. It goes away after a few seconds, I generally let it idle for a minute or so before taking off anyway.
 
The 3.6 in my wife's 2012 Grand Caravan doesn't make a bad sound on startup, but the transmission does. It whines for a few minutes when it's below freezing. I just changed the fluid with fresh ATF+4 last year.
 
Thanks Kris. Just hadn't made the noises this winter so far on the 20wt but did with the 30wt so I was concerned. My dad's on conventional 30wt doesn't make the noise at all and hasn't in 300K although his cylinder heads are the older design.

I do a ton of miles and need my vehicles to last and yes I have had my share of issues in the past with vehicles (bad luck maybe) as well I have seen a lot of issues with vehicles come through my dads shop so it has skewed my view a bit and yes it does create obsession to try and catch things before they are a major problem. This whole forum is about taking things to the next level over using a the quick oil change place at the corner so i'm not sure why me stating an experience with changing over to 30wt in the winter is a problem.

I said I wasn't worried about it up above, but am I going to monitor it to see if I can make it go away by choosing something less viscous in the winter? Maybe, but it's not like I drained the oil out and was freaking out about it. I was just trying to figure out why it decided to have a marble sound on start-up which doesn't sound like the conventional lifter sound as in Krisz's video. That's all. It's about learning through experiences.

The other ones in the family haven't although they are on 20wt, my dad's which was spec'ed for 30wt and he uses conventional doesn't either that is why I found it odd that mine did and the only thing that changed was going from 20wt to 30wt.

It's supposed to be -7c (19F) tonight and I intend on not plugging it in to see if the noise returns as it made the noise on the day after the oil change sitting at -2c (28F) the previous night.

Just trying to figure out why is all. It's interesting to me.

You might go nuts trying. It could be a lot of things that are normal. Valve timing mechanisms for example, or maybe one of the bolt ons like a alternator? Maybe some specific forums to this brand might shed some light?

Mine sounds nice and healthy running Pennzoil Ultra 5W30. Even if it sits for a couple of weeks. If it sits three or more weeks I'll hear a little noise from the valve train, but it is gone in a second or two, if that, even in very cold weather.

Based on the sounds you've posted I think you're driving yourself nuts over nothing, looking for a problem that doesn't exist. Your engine is fine!
 
I might add...I'm currently running Mobil 1 Annual Protection 0w20. It has done this on the factory fill, which I'm guessing was Pennzoil Gold 0w20, and it did it on Mobil 1 Extended Performance 0w20. It has sounded exactly the same on all 3. I've got Pennzoil Ultra Platinum 0w20 on deck. I'm at about 5,500 miles on the current fill and will probably change it between 6k and 7500.
 
My wife has a 2014 Wrangler with 60k on it, we bought it new. I have always run the 5w20 and it does have a lot of valvetrain clack at cold start. I do notice it is quieter using Quaker State Ultimate Durability or Castrol EDGE compared to Pennzoil Platinum, but in terms of longevity I doubt it makes really any difference. I just follow the OLM and change around 10-15% remaining which is usually about 6.5 - 7k miles.
 
Well it was -7c (19F) overnight and I started it this morning with no marble or noisy lifter sounds at all. So it must have been related to having just changed the oil I guess or fluke. All good it seems.

It does glide along quite nicely on the highway and very quiet I might add on the 30wt versus the 20wt. So looks like I might stick with this and try a 40wt in the summer.

I did notice a decrease in fully warmed up oil temperatures of 7c (12.6F) (same temperatures were shown across the +10c day and the -7c day we had in between the -2c days since the oil change),
I also noticed that the 30wt seems to come up to temperature faster than the 20wt did as well.

Interesting observations considering it has an engine oil to coolant heat exchanger on this engine.
