Motor leaking and hope its not a cracked block

I suppose I have to guess this is a coolant leak. That is common on any engine, and a cracked block, while always a possibility, is by far the last thing to suspect. There can be loose or rusted hose clamps, a ruptured hose, leaking water pump, leaking radiator, leaking heater core, and corroded core plugs. V-type engines usually do have one or two core plugs at the rear. You have to remove the transmission to get to them. You'll need to crawl underneath and look at them to see where the coolant is coming from. If a core plug is corroded, you'll be able to poke a hole through it with a screwdriver.
