98 4.6W rear freeze/core plugs leaking?
Hey all, been a while...Back before winter i had posted about a blocked cooling system, mystery goo and swapping out the heater core in my 98 F-150Xl...
last i did before it got really cold was run water from top to bottom and bottom(garden hose and pipe threaded into block drain) to top, and try to get all the crap out...
this past presidents day weekend i started back on the project.i pulled the water pump to make sure there was no more major blockage, impeller was a little rust coated from the goop, but cleaned up well, inside i could see a little residue from the gunk but what i could see was pretty clean, so i reinstalled with new gasket..
I then finished the heater core job, installed new radiator,thermostat, upper and lower radiator hoses and began to fill the system..
Now the new problem!!
as i was filling the coolant and getting all excited i was finnally gonna get this thing running about the second gallon in ,i hear coolant pissing on the ground..
look around, heater conections, side of motor nothing...
its coming right from the back side of the motor, possibly intake down, or my worst fear, infront of the tranny..coming from over the starter area and right out the tranny converter drain hole
i took a mirror the best i could behind the motor, hard heater lines look dry, head to block mating surfaces look dry, side freeze plugs are all dry..
i am assuming its a crack, intake, or rear freeze plugs???
my questions are:
1) is it possible even though i had the block drain open over the winter , is it possible there was water trapped in the cylinder water jackets???
2) now i cant see anything without either pulling intake or seperating tranny/motor...is it possible to pull the tranny back just enough to check the rear of the motor???
thanks so much in advance for any info and for reading
