[Mando]

Heres my problem. Ive got a 3 piece intake manifold where water exits through 4 -12 fittings, 2 at the front and 2 at the rear. I have diverted one at the rear to the heater which then exits the heater and loops around to the top connection on the water pump.
I have blocked off the lower connection.

Do I have a problem?????

Regards.
