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
|
started the engine today
no vacuum so its the intake manifold gasket |
Good deal. Glad to see the answer was found
|
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.

went out for a longer drive and lost the same amount as i did on the short drive
|
changed the water pump didn't leak at all running in the garage
short country road drive tonight pupped the hood something was glowing red under exhaust manifold heat shield lots of water leaking pretty sure its the head now going to try retorque if that dosent fix it ill have to put my winter car on the road so i can take the engine apart |
retorque fixed the leak
other thing is hesitating throttle car dosent move for a few seconds then the rps go way up thought it was the choke staying closed but taped it open didnt work once i get moving everythings good no power brakes when this is happening so im going to try the throttle body gasket |
