Connecting rod squirt holes?
This is one of the first things I was taught when I worked in a machine shop when I was a kid. The squirt hole is called a pee hole. The following is the formula to remember. "Pee-hole to the cam, numbers/locks to the outside." Now back in the 60's when I was taught this, we didn't see many or any 4 banger stuff, so can't say for sure on those engines.
