Hope i did these picturs right, basicly it is a lifted type of a crack, at first i thought it was a layer of rust peeling off, but it is pretty solid

i tried to color with a crayon so you could see the darl area of the crack , it seems to run up and down along with the back side of the cylinder jacket(valley side)

its just funny it happens to be th esame side that popped the rear passenger side freeze/core plug..

here is that thread:

well guys, i really havnt seen blcok damage from expanding ice.
does this seem like it could be the result?

not sure how else to test now, short of pulling it apart and bringing it to th emachine shop

looks like a head check and new bottom end is in order

any help is greatly appreciated

well i got the links to the gallery instead using the img icon

not sure how to actually get the actual image in the post

did it before, oh well

thanks
Chris

 

When you bring up your image in your gallery , look to the right of your image and click on forum code , a little window appears, copy the top link in that little window then paste it here.. In your post..

Thanks a bunch jbrew
Chris

 

Like so

 

Hey Faster150 , heh, ya it looks that way

i guess i should came up with a different title..i have never seen an ice crack before, trying to confirm ,\
i also guess, ice or no ice , it doesnt look good, i can only assume it goes right through into the jacket

thanks
Chris

 

Fix it. Jb weld, silicone, or take it to a machine shop, and have them weld it back up. Don't give up!

 

Is it leaking anything? It may just be a casting parting line leftover from the molding process.... the only way to know for sure is if something's coming out of it (air, oil, or water) or Magna-Flux it at a machine shop.

looks like a freeze crack if u pushed out a free plug then ur looking at a new block either way.. its very dumb to well up cast iron... u can solder it but not weld it back

 

jbrew, chester8420,GIJoe Cam, faster 150,

thanks for the replies!!!!

GIJOECam, it wasnt leaking anything before the winter, but it hasnt ran since then either so the cooling system never got presurised again ..so hard to say,it started leaking out the rear freeze plug before i ever got that far and decided to pull it, and this was upon filling the system, never got to run it..
i automaticly assumed it went hand in hand with the freeze...hard to say if these cracks were there before or not..
unless i could get some proof that this is a common thing and doesnt eefect the cooling system, i am considering it junk at this point..

sealing the crack is one thing if this is the only damaged spot, but if its on adjacent cylinder walls to, well then its done ..
only way to tell now is tear her down
, i was hoping not, but it doesnt look good..160K on the clock, previous head gasket jobs, rusty gunked up coolant passages, maybe this will be a good thing ..lol

Faster150, ya, i had been told and read many times welding and cast iron is a hard task, and considering this is the result of a water freeze, i am concerned there is damage elsewhere..it is the same bank the plug popped on

thanks a bunch everyone, i am a little uncertain here, but i think i am headed in the right direction, by not trusting it..
maybe i will get lucky and th elocal machine shop will have a 4.6 block hanging around, that my rotating assembly will fit in(providing cleaning and polish is all it needs), new bearings, rings, new bottom end...if i could be that lucky
Thanks again
Chris

 

good luck on finding a used block, i had a hell of a time finding one at all, let alone one within 600miles of me.

although i may be able to entice the e-bay idea?

plus if your patient, i have hopes n dreams to have my tired 4.6 yanked and a neat lil 5.4 stuffed in there soon.

 

4.6 longblocks are easy to come accros cause its such a common motor in both the mustang F150 and crown victoria and town car.

 

looks like a crack to me, sorry.

 

hey Klitch, Faster150,golfmjs777,
thanks for the replies made a few calls today

local boneyard wants 1500 for a 109K long block

local machine shop has 2 used motors in wich he may sell me the block

other wise they will sell me a rebiult with 3 yr unlimited mile waranty for 1500

only catch is i am unsure if that was a long block price or not

so i am going to tear her down and inspect and measure everything , let the machine shop check the heads and work on the short block deal
if that doesnt work out looks like a rebiult from them is the best bet, pretty sure i can handle puting this motor together, but it is early to tell yet

thanks
Chris
