Can you get oil pump out of time on 1992 Nissan truck?
The oil pump on a 1992 Nissan Truck cannot get out of time or sync with the engine. It physically locks into position and will constantly pump oil unless the shaft break or becomes detached.
Simply loosten the line, pump it one time , tighten it let your foot off of the brake and loosten it again and pump it one time etc until no more air comes out then do the same for the slave cylinder.Sometimes it is hard to get all of the air out but persistance will prevail. DON'T PUMP THE PEDAL as that muxes the air in the fluid.
That is the weep hole for the water pump. It means the seals are bad in the pump, and it has to be replaced. Most water pumps do have a weep hole on the pump itself. If it leaks from there it usually means that the water pump seal is going bad and soon you will need to replace the waterpump. At least that has been my experience. :-( Some water pumps do have holes…
