Re: Diesel noise explanation
Aren't motors designed to run efficiently at pretty high temperatures? So when you start up a cold motor it is not running efficiently and a motor that is not running efficiently will not sound like a motor that is running efficiently. Basically when you start your motor up and it is completely cold it is out of whack until it figures everything out and can calm down again. I think thats a pretty simple way to explain it. Good thing you don't have aftermarket cams or you would really be hearing stuff haha.
