Another Water Pump Leaking Thread- stop leak?

87 quad. Put in my new water pump, GF threw away the paper gasket it comes with so used permatex blue to create a gasket. I THOUGHT I had it perfect. Once I got everything together, there is a drop coming from the bottom of the water pump, off of the lowest bolt that connect the metal cover to the oil area. Maybe one drop every second, so enough to leak a small puddle over night, No oil is present, so I know it's not the metal cover. Went ahead and ordered the correct gasket off centerline.

Question is: Should I try to use a coolant stop leak to see if that fixes the leak? Or just rip everything out again and put on the correct gasket with some gasket sealant? Have always been weary about coolant stop leak, but don't really want to tear everything out again.

It is a new water pump from centerline and it visually looked OK. Old water pump was trash. I am assuming this is a gasket issue, but what other causes could it be, if any?

I would get a new gasket (and a new GF for that matter)
plus use thin spread sealant on both sides of gasket

when the pump is off check it (cleaned up) against the (cleaned up) front cover.....any wobble at all and the pump is poorly manufactured.

Bar's leaks liquid would also work I'm sure, but I hate any gunge like that in my block, unless a get-u-home emergency calls for it.

Yeah... Wasn't too happy, but to be fair, I had the "empty" box laying around and she cleaned up... so at $3 gasket and $8 shipping from centerline is gonna have to do :/

Agreed on the leak fix. Never worth a risk, just REALLY don't want to spend 3 hours doing this again. Oh well.

What type of sealant do your recommend so spread on both sides? I have permatext grey and blue, but heard the spray works great for this type of application.

On a side note- these new water pumps are pretty sturdy right? Let's say someone... forgot the spacer and bolted up the fan and the bolts went too far. Don't believe they got close to the actual housing, but theoretically, would they be strong enough to puncture that or is the metal pretty thick? Just going through every option here.

on something like the WP gasket I use Hylomar blue (blob on your fingers and feed the gasket thru your fingers spreading it lightly, then a minute to cure a little before fitting)
It is just to take up any micro differences in the surfaces.

But anything that is coolant resistant would do, permatex etc.

Those 3 hours work might just be 1 1/2, now you know how it goes.

not sure about the bolts, how far they would go w/o spacer (yes, read your thread where you forgot the spacer)

If its really only a drop or two leaking, just keep an eye on levels, drive it and enjoy the rest of the season...

Much appreciated. I turned the water pump when i screwed up and it turned freely... so highly doubt that it cracked the housing. But who knows, ill get it figured out.

Season might be over already up in DC, but hey the heater works. FINALLY fixed the starter after 15 years, so might just keep it filled up and drive it around this week.

It's about a drop every second, might just keep a few gallons of water in there until I get the issue fixed.

Appreciate all the help. Car is a learning curve for sure, but enjoyable. Sitting for 15 years did a number on it but it's getting there.

Alright so got the new gasket:

put permatex blue on both sides and got everything back in. Waited 24 hours to dry and...

Still minor drip at the same exact location. Bottom bolt where the oil cover for the water gasket goes on. No other leaks all around the water pump.

Is there anywhere else that coolant could be leaking out? What are the chances it is a faulty water pump (from centerline). Just doesn't make sense that both times I have put this on, there is the same minor leak in what seems to be the same exact spot. All hoses are tight. All bolts around the pump are tight.

Really debating taking it to a specialist but he moved locations and can't look at it until december. Really frustrated.
