93 lesabre makes noise after starting cold

My lesabre (135K) makes a weird noise for a few minutes when I start it after it hasn’t been running for at least a few hours.

It sounds a little like a diesel, like a chuka chuka chuka noise. It is not a sharp pop noise or a metallic noise, it sounds a little like a soft scraping. It goes away after about 5 minutes. Everything else is good with my car except no ac. it always starts fast and runs good with no burning/leaking/smoking.
My dad has a newer impala with a 3800 and it doesn’t do this. I don’t remember hearing any other car do this.
I always noticed this noise in winter, but I’m not sure if I am just noticing it more now since I have been working on the car, does anyone else have this noise

and it is definitely NOT LIKE THIS
