plug for intake

[fromthehills]

I need to find a plug to fit the hole on the front of the intake. What size is it? Also what is the hole for on the left side of the oil pan. There is a plastic cap there. This is on a 604. Thanks

the hole in the front of the intake is 3/8NPT---we like to use a brass pipe plug

the hole you are refering to in the pan is a port for your oil temperature probe it is 1/2 npt if need the size
