SOURCE: Cracked Head???
not necessarily be a cracked head but this is an indication that the head gasket is blown out
the only way to tell if its a cracked is by a machine shop milling the top layer off the head this will show in a milling that you do or you dont have a cracked head
if its cracked head you have several options dealer head brand new
remanufactured head from any auto parts store
junk yard head 50/50 chance that these heads are cracked too
mostly i think right now its just a bad head gasket have them replace both head gaskets when they do the heads better for vehicle so you dont have to run into problem again with head gaskets

take out all the spark plugs and put a radiator pressre tester on the radiator and pressurize the system, then inspect each spark plug hole for coolant. you will find out what cylinder or head will need service. How did this car run before sitting? Blue smoke is not good, although it doesnt sound like you have run it long enough to verify any real cyl problems. if its smoking it may be overhaul time. and the complete engin ewill need disassembly.

Testimonial: "Great advice, I wanted to do some initial troubleshooting before rushing in to a teardown. This is the info I needed. Thanx"
This is most likely a leak from your rear main seal. It happens and can be a pain to replace if you're a DYI kinda person without the nec. equipment.
