I replaced the radiator, heater core (ugh) and coolant hoses in my 86 GT. Went to cycle water and cleaner through because the coolant was *quite* rusty when I drained it, and immediately after starting up had a pretty steady flow coming from the weep hole on the water pump and didn’t before. So, I bought a new water pump, went to move the car over in the garage (car ran for about 5 minutes) and had no leak.

Is intermittent leaking from the weep hole a thing?

I’m going to replace the water pump anyways and hopefully not break any bolts off in the block, but I was just curious why I would have a weep hole leak and then not. (And yes, there’s still water in the car, it didn’t all leak out the first time)

I’ve not seen one be intermittent. I’d replace as well. Just me but if it’s original to the car I would think about ordering a set of water pump bolts before doing the job.
