I'm putting in a new upgraded 4.7l reman engine from Powertrains into my 01 Dodge Dakota. Everything is pretty much in order for the instal, except there are two holes in the block near the oil dipstick mount. The smallest expansion plug they make for this engine is too big. Which is .703", I'm not sure if these holes even have to be sealed off or not but better safe than sorry. Plz help if you have any knowledge about this
