honeywell CH valve leaking after motor change

[londonpuma]

Hi there,my CH stopped working so i changed the motor on my 2 port honeywell valve.

CH works fine now but the valve does not close fully now and leaks a bit when the CH is off and cools down,does not leak when CH is on and heating the house.
Did i miss something when i replaced the motor as no leaks before i changed it out.[hard to see where the leak is coming from exactly but deffo not the nuts that connect the valve to the pipes]

I cant remember but should the lever be set in a certain position before swapping,power was turned off to replace motor.
many thanks with any ideas

Ive got a new motor and will change tomorrow to see if it stops the leak,if not then its a full flush and change the whole valve.

PS: the complete valve was changed about 2 years ago

Replacing the syncron motor shouldn't cause a leak. Do you have the version where the whole actuator head can be replaced without draining? (Raised round dimple on the head). If so remove the head from the body and check the spindle for leakage. If you have the old non removeable version then it is probably leaking from seal between the head and the body.

cheers ,i took some pics and dont see raised dimples on the top so looks like a complete valve change,will take the motor off tomorrow and get a better look,what u think

latest update,so this morning i shut down the CH,when it cooled down i got the drip again,i took of the excisting motor and the drip stopped
i rewired and put a new motor in and it started dripping again so must be the valve not closing properly,i hit the valve a couple of good whacks with a hammer and guess what,it hasent dripped since,althought im keeping a close eye on it,so hopefully it was only a bit of grit or something that somehow got into the valve and the whack knocked it loose.
fingers crossed.
