Coolant pooling on rotor housings

Hi guys

Iíve recently had my engine rebuilt and Iíve put it all back together and thereís coolant leaking on top of the rotor houses on the intake manifold side .

The coolant line to the throttle body is blocked up but I donít know what else would be causing it to leak like that . Ive checked on the coolant diagrams but canít see anything

Any help would be appreciated, Iím having a melt down right now

Do you still have your rear iron coolant nipple? I would check around there. Could be a leak from the rear of your water pump housing too

I would mop up all that coolant then get a coolant pressure tester that can pressurize the coolant system. Then see where the coolant is coming from.

Hopefully it's just an external hose that's leaking or something. Worst case would be a pinched water seal in the engine.

There are so many things it could be. Tiny pinhole leak somewhere will spray a tiny stream that can be pretty well directed to a place like this from further away than you might think.
As Dale said, pressure test it.

Housing to intake manifold O-rings are common failure too.
