Where is this coolant leak coming from?

[g356spd]

I have a large coolant leak from the rear freeze plug on the block. I removed the trans and freeze plug, but then i saw that some coolant was also leaking from higher up. heres a rough picture of what i am talking about.

i cant tell what im looking at. I dont see any coolant leaking from that plug. If its leaking from the rear as you said its probably either the head or the coolant port in your intake manifold. Is it coming from the middle, or off to the side?

If thats the cps near the top of the pic (look like youre pointing at it) then it looks like your intake manifolds leaking.

the leak was from the block freeze plug which i already removed in that photo. It appears to be coming from what i think is the coolant temp sensor area and running down the rear of the pass head/block junction. When i was under the truck with the trans removed, there was a flow of water from the middle of the block (middle freeze plug) and one that was leaking from the far pass side of the block

The coolant temp sensors are all at the front of the engine

a head gasket is a high order possibility. particularly near the rear of the passenger side cyl head.

The Picture in the post above is the REAR of the engine, you can see the Cam syncronizer at the top of the pic and the bellhousing bolt holes.

It is a pic of the passenger side head from the REAR

The water pump is at the FRONT
