Default water leak after putting head back on

torqued the head down yesterday 89 civic d15b2(engine hasnt run yet)
water driping down the side of the block where timing belt goes
either water pump intake manifold or a problem with the head

was wet under the intake manifold today its dry but still driping down the side so i think its the water pump but what would cause the water pump to leak after having the head off/cleaning

Was the head mating surface and deck of the block warped at all? Is the head gasket seated properly? Is there play in the shaft of the water pump? Are all hoses connected properly? Those are the questions I would ask myself

now that i think about it whats dripping is clear(just filled the rad with water still need to flush) whats in the block is old green coolant so its on the inlet side of the system so probably the pump

changed intake manifold gasket
runs smooth now
but still leaks now only when running
did a short loop around town pulled back in my garage and was dripping
after about 6 minutes stopped dripping
was down about 700 ml


cant see the leak but dripping from timing cover and oil pan area


drips most right after stopping the engine hot

Buy a cooling system pressure tester. Check the cap and see what psi it should hold, usually like 1.1 bars so pump up like 15 psi in to the system a d see where it leaks, the pressure will force it out wherever it's coming from.
