I've noticed some noise on lots of our car's on cold starts lately. Mostly when it's below freezing though. I hear some pretty awful noises on some cars after an oil change that last make me cringe. Others are pretty quiet.

This was my new engine from salvage after not being run for who knows how long (it's a 2017 w/ 20k miles, so couldn't have been too long). Lots of valve clatter for about 4 seconds until the oil pressure came up. Maybe a little more than the typical post-oil-change start.
Simplify and add lightness.
It could very well be a no-oil-rattle on startup.
Because of that I changed my OEM oilfilter to a Filtron OP525, which includes a silicone non-return valve plus bypass valve, and the rattle is gone. With the cheap little OEM filter without a non-return valve they put on during yearly serviceing, the rattle regularly comes back, so I just put another OP525 back in and the rattle is gone again.

I have decided do use a filter with an ADBV or ADV (anti-drainback valve) and change viscosity from 5-10 to 20-30 synthetic. My next oil change should determine if it will work or not.

Sorry about the typo.....I meant 10-30 synthetic. I don't want to go over that. I hadn't had my five cups of coffee yet so I was still in a brain-fog LOL.

Bringing an old thread back to life here but it seems like it's the camshaft actuator rattling on cold start all this time. https://youtu.be/gwJ5BBHb9W4
I have a 2017 G4, 53,000 miles. I have had this problem since 24,000 miles. I cured it a year ago by switching to 5W-30 Castrol Magnatec oil, and a fram tough guard oil filter.
The mitsu oil filter was strange no start up noise until I got 1,500 miles on the oil. I had this phenomenon happen to me more than once, until a made a oil filter switch. I can truthfully say it's gone now even in sub-zero temperatures.

I took my 2014 in for occasional weird start up noises awhile back to a 40 year master mechanic I trust. He basically said nothing is wrong with the engine. It's a tough but archaic, unrefined 3pot. Its going to make weird noises sometimes. Nothing to worry about.
