Yea its definitely louder in a drive thru line next to the wall.. its very annoying. Im thinking the oil pump as well, oil pressure does sit a little low (for my liking) at idle. if the guage is correct. The motor is noisy as well, alot of ticking from top and bottom end. i was told it normal, they used noisy pumps and they all sound like that i might change oil brands and a better filter to see if anything changes, if not i guess im stuck with a 2020 truck that sounds like a 95 cavalier.
