Coolant is SPRAYING, like a straight pin point shot from under the intake manifold on the thermostat side, under the 2nd bottom bolt over for the IM... Sprays straight back towards the firewall. Its in a spot where I cannot see where it is coming from... when feeling around all i can find is the line that goes into the block that runs straight into the the black oil seperator box... ANY IDEA ON WHAT IT IS?

Just put the motor together...

 

after further investigation with the help of a mirror I have found the problem... THERE IS A SMALL PINHOLE IN THE BLOCK!! must have been there from the kid i bought it from... anyway... JBWELD?

 

man i would beat his ***. yes jb weld should work if its not too big or a hole. make sure you get it dried off really well.

 

sure it's from the block? engine block casting voids can look like pinholes at times but harmless. i had a coolant spray under my hood after a long drive at 5krpm. minor coolant hoses around the thermostat housing area (about the same place where yours sprayed) worn out and gave way under pressure. changed those and good to go.

 

nope def from the block... i can see exactly where it is coming from when i stick a mirror down there... i had a couple people look at it and they say the same thing
