well it turns out my "tap" is a "rap" and i gotta either split the block and take a peek or drop a new one in, i have an opportunity to pick up a short block from an 89 Eagle premier ES with low mileage, this is a 3.0l block and i have been informed that "engine doesn't have balancer shafts" whatever that might mean, i know i have to keep my old oil pan, but will i need to do a head transplant?
