My 2005 4runner with 150,000 miles makes the same normal noises with the hood up.
You all worry about nothing. Wait until something breaks. Why spend money on service repairs and parts for nothing.
Geeze....
The Making of "Full Metal Jacket" - YouTube
Basic at USAF outside of San Antonio - about the same BS.
The best part of "basic" is getting to fire 90 rounds out of an M-16 in three positions (i.e., prone, sitting, standing). Remember?
Standing is the hardest. I shot 80 out of 90. Two in my platoon shot 90 out of 90 bulls eyes.
Very good weapon is the M-16.
I think the targets were 100 yards away.
