1996 S10 4.3L Cooling System Help!

I realize I posted this in the 4.3L section, but I'm hoping it will get some good traffic and advice in here. i need the truck for tomorrow and was going through roughly 1+ gallons a week.

Had a coolant leak from the front of the truck, saw a couple of cracks in the radiator so I went ahead and replaced the radiator and the upper and lower hoses. Now I have a leak from somewhere in the back of the block, it runs down the transmission. It's not a drip but a steady stream, someone help me quick. Any help PLEASE!

Well, it sounds like an intake gasket to me.

intake gasket?

i believe coolant in the back is a symptom of that but I could be (and most likely) wrong

edit: damn you jason haha

not off the top of my head

also check the heater core lines, I thought i needed a new intake gasket but I actually had a cut in the line going into the heater core and it blow out coolant under load.

It leaks with just the truck running, no extra load needed, and the heater core was just replaced 2 winters ago, with new lines and everything so not that.

check your oil to see if theres coolant in your oilpan

if there is it's 99% likely your intake gasket, which is a $30 dollar fix (if you do it yourself)

No coolant in the oil, just changed that last weekend (August 7) and it was clean as a whistle.

Its impossible to diagnose over the internet. You need a pressure tester and a good set of eyes. The replies give you a few places to start looking though.

I didnt even think of heater lines/core, but all that is right there also.
